Overview
Overview
The Model 7780 Distributed Lighting Control Unit (DLCU) from Control Systems
International (CSI) is a high-speed, fully-distributed, microprocessor-based controller
used with the I/NET integrated network system. The 7780 connects directly to the
controller LAN and works in conjunction with other controllers and workstations on the
LAN.
The 7780 is a specialized DCU that controls up to 64 lighting control relays in its
maximum configuration. The 7780 is similar to the 7716 controller, but is designed
specifically for lighting control. The 7780 has the following features:
✦
✦
✦
✦
✦
✦
I/NET Lighting Control editor. The 7780 has a related I/NET editor you use to
define each point controlled by the 7780. The point definition includes creating a
time schedule, entering the zone, circuit, override switch names, zone schedules,
zone wink parameters, and zone override times.
Trending. Select an internal maximum sample register of up to 1440 samples on a
database point.
Support for up to 64 relays.
Definable inputs. The base card has eight universal inputs which you can define as
analog, discrete, or pulse.
Input Filtering. The 7780 firmware employs analog scan techniques and
processing to minimize the effects of noise on the analog signal input.
Input Transient Suppression. All inputs on the base card are equipped with transient suppression components.
Controller
The 7780 combines processing, memory management, communication, and field
input/output functions on a single printed circuit board. The controller board features
quick-disconnect terminal blocks, firmware you can download, onboard modem
drivers, and a direct-connect RS232 port. The inherent reliability of this design is
enhanced with extensive transient protection, automatic self-test features, and a fiber
optic communication option.
Microprocessor
The 7780 controller is based on the Zilog Z181™ microprocessor. This new, highly integrated, high speed microprocessor supplies a number of on-board functions and
features along with expanded memory access.
The on-chip integration of asynchronous and synchronous communication, Memory
Management Unit (MMU), Direct Memory Access (DMA), multiple timers, interrupt
control and parallel I/O, coupled with the increased processor speed and an enhanced
instruction set, provides an efficient and powerful package well suited for data acquisition and control applications.
7780 DLCU

Overview
Installation Guide
Communication
The 7780 has these communication ports:
✦
✦
✦
✦
One standard synchronous RS485 LAN port
One asynchronous serial port for PC or auto-answer (i.e., Integrated Dial) modem.
When connected to a PC, the 7780 has the function of a 7801 Tap, but does not
consume a second LAN address. When connected to a Hayes-compatible modem,
the 7780 provides one-way dialing from the host PC to the controller LAN.
One asynchronous port provides a modular TTL-level interface for a standard
HC7410 hand-held console and operates at 1200 baud.
An optional plug-on board provides an RS232 synchronous (SDLC) or asynchronous serial port. Use this port for an external auto-dial/auto-answer (AD/AA) or
direct-connect modem, or one of several other RS232 communication devices.
Inputs
The 7780 base card has eight universal inputs. These can be defined as discrete, pulse, or
analog inputs. If you define a contact switch as a discrete input, you can use it for
ON/OFF or override control. If you define an external sensor such as a photoelectric cell
as an analog input, you may use it to influence output control strategy.
Input Expansion Cards
The 7780 can be expanded to provide a total of 32 inputs by adding up to three DLCU
Input Expansion Boards (Model L8UI). Each card provides eight universal inputs on two
8-position terminal blocks. If you add more than one input expansion card, each additional card is attached to the previous card with a ribbon cable, creating a “daisy chain”
of expansion cards.
Outputs
The lighting control outputs are provided by the base card and are distributed through
matrix cards to the lighting control relays. These relays are General Electric RR7P3 relays,
typically available from General Electric distributors. The relays mount on panels in the
upper right and left portions of the enclosure. You may mount up to 32 relays in the basic
enclosure. If you need more than 32 relays, you must purchase the expansion enclosure
that allows you to add an additional 32 relays for a total of 64 relays.
Matrix Cards
The relays do not connect directly to the base card. Instead, each relay is plugged into a
DLCU Matrix card (L16DO). You may attach up to 16 relays to each matrix card. There
is a maximum of two matrix cards in the basic enclosure and an additional two cards in
the expansion enclosure. The first matrix card in each enclosure attaches to the base card
with a ribbon cable. The second matrix card in each enclosure is attached to the first card
with a 3" (7.6 cm) ribbon cable.
Self-Test
When the power is restored after a power loss, the 7780 executes an automatic test of
RAM, EPROM, and NOVRAM. If the memory check is successful, control and execution
is passed to programmed RAM memory.

The Enclosure
Enclosures provide a protected environment in locations where dirt, dust, or other
contaminants may exist. The model used for the 7780 measures 26" H × 19" W × 5" D
(66.0 × 48.3 × 12.7 cm). The same enclosure size is used for the base assembly and the
expansion assembly. Each enclosure contains four 1/2-inch knockouts, two in each
bottom corner.
The enclosure design lets you mount the baseplate on either the door or the back panel.
This creates additional space for optional equipment such as transformers and electrical
junction boxes. The enclosure locks with a regular door key lock.
7780 Configurations
The 7780 is constructed to let you connect all field terminations quickly and easily. The
RR7P3 relays mount on two 2-tiered panels that separate the low- and high-voltage
sections of the enclosure. The relays are located in the upper left and right portions of
the enclosure. The two-tiered panels separate the low-voltage relay coils (and the rest of
the enclosure) from the high-voltage relay terminations.
The matrix cards are positioned between the relay panels. The base card is located in the
enclosure below the matrix cards. A compartment containing a 120-to-24 VAC transformer is located in the bottom right corner of the enclosure.
Figure 2, below, shows the basic enclosure containing its maximum capacity of 32 relays
and two matrix cards. An optional input expansion card can be mounted using SnapTrak™ mounting to the left of the base card. Other components are shown in their
respective locations.
The expansion enclosure assembly is identical to the base assembly, except that it does
not contain the base card or transformer. Input expansion cards, relays, and matrix cards
are available for the expansion enclosure.
Basic Configuration
The basic configuration lets you control 16 or 32 lighting circuits. Sixteen relays require
one matrix card connected to the base card with a 9" (22.8 cm) ribbon cable (part
#606105-0040). Thirty-two relays require two matrix cards with a 3" (7.6 cm) ribbon
cable (part #606105-0039) connecting the first and second matrix cards.
Configuring a Unit with 16 or Fewer Relays
If your 7780 configuration requires 16 or fewer relays, we recommend you populate only
the bottom eight (or fewer) relays on each side and connect them to a single matrix
board. However, if you must mount nine or more relays on one side of the enclosure, you
will need to use two matrix cards. This arrangement leaves a void of eight numbers in the
relay (lighting circuit) sequence between the first eight relays and the second eight relays.

Optional Expansion Configuration
If you need more than 32 relays, select the optional expanded configuration which
includes a second enclosure. This lets you control up to 32 additional relays, which
brings you to the 7780 maximum configuration of 64 relays.
In the optional configuration, the base controller is connected to an expansion enclosure, which is the same size as the basic enclosure. This expansion enclosure contains
optional input expansion cards, lighting relays, and the matrix cards. The matrix cards
in the expansion assembly are connected to the base assembly using a 72" (182.8 cm) 20conductor cable (part #606105-0041). Optional input expansion cards in the expansion
assembly connect to the base card through a 72" (182.8 cm) 10-conductor cable (part #
606105-0044).
If you are expanding with 16 or fewer relays, use one matrix card. If your expansion
requires more than 16 relays, you must add two matrix cards.
Figure 5 shows the maximum configuration with all three optional input expansion
cards, all four matrix cards, and 64 relays. The expansion assembly must be within
2 ft. (0.6 m) of the base assembly since the length of the cable connecting the two items
is 6 ft. (1.8 m). You can place a single input expansion card in the base enclosure and two
more in the expansion enclosure. If you need more than 64 relays you must purchase an
additional controller (L8UI).

NOVRAM
The 7780 also provides 256 bytes of serial nonvolatile RAM (NOVRAM) storage. This
memory holds information needed to establish basic communication with the controller
after a long term power outage when battery-backed static RAM is lost.
The base unit configuration of the 7780 provides 96 KB of battery-backed static RAM for
software data storage and imbedded 7801, 78035, and 78061 Tap functions such as
message queue, dial telephone numbers, and asynchronous/synchronous communication buffers. This memory is retained in the event of a power outage, as long as the backup battery has power. When the battery power is depleted, the static RAM is cleared.

Physical Description
Installation Guide
Note:
The backup battery must be fully charged in order to provide the full span of backup power.
Due to normal discharge during product storage and shipment, the battery may not be fully
charged immediately following installation and power-up. You must allow the controller to
operate continuously for a minimum of seven days (168 hours) before depending on battery
backup.
The software may be downloaded while the 7780 is on-line with I/NET. The software
design and memory organization supports the complete download of all software. The
downloaded software is held in RAM.
EPROM
EPROM stores boot-up firmware of the controller, as well as a firmware download
handler and boot record firmware.
Memory Exhaustion Warning
The 7780 editors provide a warning message when you add a point or function that could
exceed the remaining available memory.
Memory Management Unit (MMU)
This unit provides 20-bit addressing and 1 Megabyte memory access.
Power Supply
The 7780 is powered by a single 24-volt AC 40 VA external transformer connected to a 3pin terminal block (TB5) located at the far right bottom edge of the base card (see
Figure 1 on page -3). This AC input provides power to the following internal power
supplies on the base card:
✦
✦
✦
✦
A switching power supply circuit generates the +5 VDC logic power.
+15 VDC. This supplies voltage for RS232 communications devices.
+15 VDC Ext. This regulator supplies separate current loop excitation power to
avoid communication loss due to a field sensor wiring problem.
–15 VDC supply voltage for RS232 communication.
Inputs
Eight universal signal inputs are located along the bottom left edge of the base card. Each
input can be defined as discrete (DI), analog (AI), or pulse (PI), but only one input type
can be assigned per input. These inputs typically connect discrete contacts from override
request switches at the controlled location.

Each input has a plug-on terminal block with two screw terminations (one contact and
one ground) to connect the field inputs. Pulsed signals typically originate from devices
such as electrical metering and other equipment producing signals no higher than 5 Hz.
Analog inputs allow sensing of 0–5 VDC, 0–10 VDC, and 0–20 mA analog signals (0–255
counts). This includes indoor/outdoor light levels (from photocells, etc.) used to inhibit
or enable perimeter and outside lighting, the light level setpoint for staged lighting and
miscellaneous sensor inputs used for facility control and/or monitoring.
Discrete/Pulse Input Scanning
Discrete and pulse inputs are scanned and the points are tested for a value to determine
if the device is an open or closed contact.
✦
✦
Closed contact: A value below 25% scale (64 counts) is considered a closed contact.
Open contact: A value above 75% scale (192 counts) is considered an open contact.
When the system detects a state change on a DI or PI point (within 100 milliseconds),
the 7780 immediately processes any attached event detection and sequence processing
along with state change/alarm messages.
External Analog Input Power
TB3 at the bottom center of the base card (see Figure 1 on page -3) supplies power for
any external analog sensor inputs you might have. The maximum current available from
the +15 VDC and +24 VDC supply is 160 milliamperes. There are three terminal posts.

Outputs
The 7780 offers the following output features:
✦
✦
✦
✦
✦
A maximum of 64 latching relay outputs are supported.
Hardware output point addresses are 0000–0707.
Indirect output point addresses are 0800–1107.
Zone definitions are on bits 0–7 on points 12–15.
Internal software output point addresses are on bits 8 and 9 on points 00–31 and
bits 0–7 on points 16–31.
The 7780 has two ribbon cable ports, one for each set of 32 lighting circuits, with each
cable supporting 1 or 2 matrix cards. Each matrix card supports up to 16 relay terminations. A plug-on connector connects the GE RR7P3 relays to the matrix adapter board.
The relays have three 6" (15.2 cm) leads that terminate in AMP 640432-3 connectors.
Matrices
The 7780 output configuration involves one or two matrices, depending on the number
of relays your facility requires. Each matrix consists of eight sourcing driver outputs and
eight sinking driver outputs. These groups combine to create an 8 × 8 (64 point) matrix
which controls the ON and OFF coils of 32 relays. The actual 32 relay terminations are
divided between two physically separate matrix cards. You only need one matrix card if
your installation has 16 or fewer relays.
If your facility requires more than 32 relays, you must purchase the expansion enclosure
and install one or two additional matrix cards. These matrix cards form a second matrix
that is identical to the first. There is a maximum of 64 relays per 7780 controller.
Relay Control Coils
An RR7P3 relay control coil is positioned at each cross point on the matrix. When the
7780 controls more than one relay, it sequences through the database of zones and zone
schedules you defined using the Lighting Control editor in I/NET, individually energizing the ON and OFF coils of the appropriate relays. Both sink and source drivers are
deenergized upon power-up and after any control action.
Assuming the 7780 is controlling 10 relays, the sequence takes slightly longer than one
second to accomplish if the momentary output duration is set to 0.01 seconds, and just
over two seconds if the duration is set to 2.55 seconds.
Note:
When using standard GE RR7P3 lighting control relays, the momentary duration value
should be set to a minimum value of 10 (0.1 seconds).
The momentary output duration can be set through the hand-held controller. Refer to
“Momentary Output Duration” on page -28 for more information.

This section gives you all the information you need to install the 7780 enclosure as well
as install the inputs, outputs, and related devices. The following steps describe the 7780
installation procedure. Please follow the steps in the order listed.
Warning:
Warning:
Make sure there is no power connected to the 7780 when performing these procedures.
Failure to disconnect power from all interconnected equipment when performing electrical
installation may result in damage to the components, electrical shock, or burns.
1.
Create appropriate knockouts in the enclosure(s) if necessary. You will need to cut
an access hole for the power cable conduits feeding the lighting control relays. The
lighting circuit wiring must be in separate conduits from any inputs or control
expansion outputs or communication conductors.
2.
Mount the enclosure on a suitable wall. Refer to Figure 1 on page -3 for a keyhole
mounting diagram.
3.
Make sure there is no power connected to the 7780 or any devices you plan to
connect to the 7780.
4.
Bring the conduit(s) containing the power cables into the enclosure. You need one
conduit leading to each set of relays. Remember to keep the lighting circuit wiring
separate from input and control output wiring.
5.
Mount the baseplate with the attached base card in the enclosure using the available keyholes in the baseplate.
Route all wiring along the sides of the enclosure. Do not place any wiring across the base
card.
Installing the Optional Cards
If you purchased any optional input expansion cards (L8UI), install them now. Optional
universal input expansion cards have Snap-Trak™ mounting. You can mount them
wherever it is most convenient for you, inside or outside of the enclosure. The limiting
factor is the length (6 ft. or 1.82 m) of the cable connecting the first expansion card to
the base card.
Matrix cards are installed inside the 7780 enclosure and between the lighting relays. You
may mount up to two matrix cards in an enclosure and an additional two may be

Mount the first input expansion card using the Snap-Trak™ mounting within 6 ft.
(1.82 m) of the base card.
1.
Locate port P3 at the top left of the 7780 base card. It is to the right of the on-board
RS232 port.
2.
Locate the 9" (22.8 cm) cable (CSI part no. 606105-0043) or the 6" (15.2 cm) cable
(CSI part no. 606105-0044). Connect the cable to the first input expansion card at
P1. Connect the other end of the cable to the base card at P3.
3.
Connect any additional input expansion cards to the first using a 3" (7.6 cm) cable
(part # 606105-0042) between ports P2 and P1, creating a “daisy chain” of expansion cards.
Configuring the Jumpers
All input expansion cards are identical as shipped from the factory. Each card has a 3position plug-on jumper that must be configured to establish the address of the eight
points on the card. Configure the jumpers as shown in Table 5.
Configuring the Inputs
The input expansion cards are shipped in a discrete/pulse input (contact sensing) configuration. You may also configure the inputs for 0–5 volt high impedance, 0–10 volt analog
input range, or 0–20 mA current sensing by replacing the resistor for that input or
placing a resistor in a different position. Refer to “Input Resistor Configuration” on page
-21 for the procedure.

cable passes through each controller. Shield drain wires from each LAN cable segment must
be spliced together, insulated, and tied back such that wires do not come in contact with
ground or any conductive surface within a controller.
Connecting the Input Field Connections
The 7780 supports several types of inputs, each using different field connections. Use the
procedures shown below to connect the sensor you use to the 7780. Connections to an
L8UI Input Expansion Card are the same for like types of inputs on the 7780 base card.
Caution:
The input, output, and power wiring must be routed along the side of the controller. The
wiring is not to lay across the controller.
0–20 Milliampere Sensors
0–20 milliampere sensors can be connected as shown in Figure 14. Use a 249-ohm ,1/8
W, 0.1% resistor in the corresponding resistor position (A1 through A8). See Figure 17
for resistor installation.

Connecting the Lighting Circuits
Warning:
Hazardous voltages may cause severe personal injury or death!
Connecting the lighting circuits involves working with wiring which normally carries
hazardous voltages (115–277 VAC). Make sure that the 115–277 VAC source supply for
ALL lighting circuits is disconnected or switched off at the circuit breaker before you
make any output relay connections.
1.
Disconnect or switch off all 115 VAC source power.
2.
Determine which lighting circuits will be controlled from each matrix card output.
Verify that the total lighting load of each circuit does not exceed the maximum
contact rating of the RR7P3 relays.
3.
Bring in each lighting circuit wire pair (up to 16 pairs per side — 32 per enclosure)
through the dedicated wiring conduits into the high voltage areas of the RR7P3
relays.
4.
Connect each lighting circuit wire pair to the relay contacts at the base of each relay.
Make sure there is no bare wire exposed at these connections and that each is tightened securely.
5.
As you connect each lighting circuit to each relay, record this information in the
Output Description Matrix Table located on page -41 of this document. By
recording which lighting circuits connect to which relays, you simplify future
maintenance and repair.
Connecting Relays to the Matrix Card
Connecting the lighting relays to the matrix card enables the 7780 to control the operation of those relays. Use the following procedure.

Grounding Requirements
To ensure proper operation of the controller, it is imperative that the unit be correctly
grounded as follows:
✦
✦
✦
7780 DLCU
Terminal 3 of TB5 must be connected to a good earth ground through the best
means possible. This should be accomplished by connecting a 14–18 AWG
(2.081–0.897 mm2) wire from terminal 3 of TB5 to metallic structural components
known to be grounded. The controller depends on this ground path for transient
protection.
Do not connect the controller LAN shield drain to the LAN terminal block (TB4).
The controller LAN shield drain must be connected directly to earth ground at one
location only. (This may be at the DLCU.)
Shield drain wire continuity must be maintained as the LAN cable passes through
each controller. Shield drain wires from each LAN cable segment must be spliced
together, insulated, and tied back such that wires do not come in contact with
ground or any conductive surface within a controller.

are used for other hardware inputs, the lighting circuits controlled by the 7780 DLCU will
turn on/off unexpectedly.
Programming the 7780 from the Host PC
Program the 7780 from the host PC. Refer to the I/NET Operator Guide for instructions.
The I/NET installation disks provide a default save file named 7780.SAV. If the default is
supplied, and you select Database from the software restore function, and a *.SAV file
does not exist for the selected DCU, the default is copied to the DCU and to a *.SAV file
with the appropriate name.
Cold Starting the 7780
There are occasions when you may wish to perform a cold start (i.e., clear the database)
on a 7780 currently operating on the LAN. The simplest way is to reinforce the same LAN
address.
1.
Press [DCU ADDR]. The current 7780 address displays in the two right-most digits
of the HHC display.
2.
Enter the same address using the number keys. The address displays as you enter it.
3.
Press [Enter]. This clears the 7780 RAM (including all database information) and
stores the 7780 LAN address.
7780 Operation
LED Indications
The 7780 provides LED indication of transmit and receive data on the hand-held
console, LAN, and RS232 ports. The controller also provides an indication of relay
output activity with an alarm LED that blinks each time the 7780 pulses/controls a relay.
The alarm LED also indicates successful power-up and operation of self-test routines. If
the LED flashes continuously, this indicates the self-test failed. A fast flash (four times per
second) indicates a hard failure (failure of RAM, Clock/Calendar, SCC, RTC, etc.). A
slow flash (once per second) indicates a loss of RAM memory. If the alarm LED is continuously illuminated, this indicates that a point in the controller is in alarm.
The LEDs show the status of communication in the controller and other information.

Setup and Operation
Installation Guide
Input Setup
You may configure the 7780 inputs for Discrete/Pulsed, 0–5 V, 0–10 V or 0–20 mA input
by removing or adding resistors in plug-in resistor positions A, B, or C. Refer to “Configuring the Inputs” on page -13.
Power Line Frequency Selection
Use the hand-held console (code 92) to select the power line frequency (50 or 60 Hz).
This selection is used to establish a power line frequency notch filter that reduces or eliminates random electrical noise, which normally shows up as very high or very low input
readings. The procedure is described on page 24.
All Lights On/Off
Use the Lighting Control editor in I/NET or the hand-held console to define two of the
eight universal inputs, 0000 and 0001, as the ALL LIGHTS ON and ALL LIGHTS OFF
overrides. These functions are defined in NOVRAM and are never lost because of RAM
firmware or database loss. Refer to the TCON142, I/NET Operator Guide, or TCON207,
I/NET 2000 Operator Guide, for more information on the Lighting Control editor. Use
the hand-held console (code 08/09) to select All Lights On or Off. The procedure is
described in “Setting All Lights On/Off ” on page -25.
Note:
If code 08 and/or code 09 have been used to enable the “All Lights On” and/or “All Lights
Off ” functions, input point addresses 0000 and 0001 will control the lights as desired. In
this case, do not use these input points for any other hardware inputs. If these input points
are used for other hardware inputs, the lighting circuits controlled by the 7780 DLCU will
turn on/off unexpectedly.
Momentary Output Duration
The 7780 lets you define the momentary output duration on a controller basis. This
parameter defines the duration of the momentary output controls (sink and source
drive) used to turn the lighting relays ON or OFF. The range is 0.1 (default) to 2.55
seconds. Use the hand-held console (code 7) to set the momentary duration. The procedure is described in “Setting Momentary Duration” on page -25.
Communication Ports
There are three communications ports on the 7780 board. The two asynchronous serial
ports on the 7780 base card provide access to a PC or modem and the hand-held console.
An optional communication board can be added as a plug-on daughterboard (refer to
“RS232 Serial Expansion Port” on page 30). All connections to the LAN, modems, PCs
and the hand-held console are made using these ports.
PC Port (P4)
You will normally use this port to connect a computer, but you may also connect an
external auto-answer Hayes-compatible modem.
The following cables are all six feet in length. Use cable number CBL072 for 9-pin PC
connections and CBL073 for 25-pin PC connections. Use cable number CBL074 to
connect the 7780 to a modem with a 25-pin connector.

If you connect the 7780 directly to a PC, the 7780 functions like a 7801 Tap, but does not
consume a second LAN address.
If you connect the 7780 directly to an auto-answer Hayes-compatible modem, the 7780
provides one-way dialing from the host PC to the controller LAN. The following table

LAN Port (TB4)
The 7780 controls this serial port using a Synchronous Data Link Communication
(SDLC) protocol from the microprocessor. This sets up a token passing bus that regulates
access to the controller LAN.
The normal baud rate for the controller LAN is 19.2 KB, but you may select 9600 baud
for lower-grade cable installations.
Hand-held Console Port (P10)
The hand-held console, or HHC (CSI part # HC7410), is required to complete various
aspects of the 7780 installation. You must use the HHC to set the LAN address and the
baud rates for the LAN and PC/modem ports before you connect the 7780 to any of these
items. You must select an address between 0 and 63 that is not already used by any other
device on the LAN. Two devices sharing a LAN address results in severe operational error
and/or loss of system communication and subsequent system failure.
You may also use the HHC to select the host port. You have the following tap communications options:

Installation Guide
RS232 Serial Expansion Port
The RS232 serial expansion port is an optional serial interface that supports userselected data rates up to 9600 baud. This optional interface can be connected to any of
the following devices:
✦
External auto-dial/auto-answer (AD/AA) modem — When connected to a Hayescompatible AD/AA modem, the 7780 will provide the functionality of the 78061
Tap. The following types of modems are supported:
✧ Synchronous — Use a synchronous modem when the controller is loaded with
an I/NET version 4.x or earlier binary file. The controller must also have
I/NET version 4.x boot firmware (EPROM).
✧
✦
✦
Asynchronous — Use an asynchronous modem when the controller is loaded
with an I/NET 2000 binary file. The controller must also have I/NET 2000
boot firmware (EPROM).
Use cable number CBL048 for connecting to either of these modems. Refer to
TCON145, I/NET Technical Reference Guide, or TCON209, I/NET 2000 Technical
Reference Guide, for more AD/AA information.
External synchronous dedicated line modem — When connected to an external
Hayes-compatible dedicated line modem, the 7780 provides the functionality of a
CSI 78035 Tap. Use cable number CBL048 for this connection. Refer to TCON101,
I/NET Tap and Repeater Installation Guide, for a complete description the 78035
Tap function.
Another RS232 data communications device.
Refer to TCON101, 7800 Series Tap and Repeater Installation Guide, for details about CSI
Taps.
Tap Emulation
The 7780 controller can be configured to emulate several types of CSI Taps, as follows:
✦
7801 Host Tap — Using this emulated Tap, you can connect the following devices
directly to the 7780 controller at port P4:
✧ Host Workstation — This connection supports the “Direct-connect” function
of the 7801 host Tap.
✧
✦
✦
30
Asynchronous Hayes-compatible Modem — When the modem is configured
to auto-answer incoming calls, this connection supports the “Integrated Dial”
function of the 7801 host Tap. This configuration allows you to use voicegrade phone lines to communicate with the controller LAN from a remote PC.
78035 Site (LAN) Tap — This emulated Tap requires the use of an optional RS232
expansion module. Using this Tap function, you can connect a synchronous dedicated-line (i.e., leased-line) modem to port P2 of the RS232 expansion module.
78061 Dial Site (LAN) Tap — This emulated Tap requires the use of an optional
RS232 expansion module. Using this Tap function, you can connect a Hayescompatible modem to port P2 of the RS232 expansion module. You may then
7780 DLCU
Installation Guide
Setup and Operation
configure the modem for auto-dial/auto-answer (AD/AA) operation (refer to
“Modem Switch Settings” on page 33).
Note:
Ensure that all AD/AA Taps within your I/NET system are configured to use the same
communication protocol — either synchronous, or asynchronous. Mixing AD/AA protocols
will cause communication errors. Refer to the communication chapter in TCON145,
“I/NET Technical Reference Guide,” or TCON209, “I/NET 2000 Technical Reference
Guide,” for more information about AD/AA communication.
I/NET 2000 is compatible with I/NET version 4.x Tap and controller binary loads. Therefore, when synchronous AD/AA communication is required on an I/NET 2000 system (for
example, when using a 78040, 78050, or 78060 Tap), you must continue to use I/NET
version 4.x Tap and controller binary loads.
If Tap emulation is used, the total memory available in the 7780 is reduced by 8K bytes.
When the 7780 is emulating a 78061 Tap, it can store telephone numbers. You can store
up to eight telephone numbers of up to 25 digits each. You may also use the 78061 Tap
emulation in conjunction with beeper and pager operation.
78061 Tap Emulation and Beeper Operation
Beeper calls are used to notify a user of a specific condition occurring in the I/NET
system. This condition is user-definable using message masking and priorities. The
beeper is only a notification tool. It contains no originating code or phone number. It
issues either a tone or vibrates the beeper. To specify a beeper call, select Beeper in the
Type field of the 7806 Configuration editor. If a beeper service is used, enter the beeper
service phone number. If a human response is expected, enter an @ symbol at the end of
the beeper number. This will allow the 78061 Tap emulation to retry on busy and noanswer conditions.
The @ symbol will cause the modem to listen for a 5-second period of silence after the
first ring is detected. The length of time that the modem will listen for this period of
silence is established by the Timeout field in the editor. If a period of silence is detected,
the call will be considered complete.
Note:
Some experimentation with the timeout period that is set in the Tap editor may be
required. This timeout period should be set long enough to cause the modem to “hang on
the line” until the 5-second period of silence can be detected.
Since this beeper function is used internationally to dial out to numbers that must have
a human response, it is necessary to accommodate differences in the manner in which
beeper systems and humans respond. When using an external modem (78061 Tap
emulation) you should initialize your Hayes-compatible modem with the X4 command
(factory default), which enables your modem to return the busy response code if it is
expected that a person will answer (or not answer) the telephone. This will provide a
rapid response to a busy error.
Note:
It is imperative that any modem used for beeper interfacing operate as described above.
The 78061 emulation will alter the modem initialization timing sequence to always
initialize at a 2400 baud data rate.

Installation Guide
Note:
The 7780 DLCU will send a setup string to the modem to place it in the auto-answer mode.
This auto-answer function will be set to answer on the first ring.
78061 Tap Emulation and Pager Operation
Select pager operation in the I/NET software by selecting Beeper from the Type field.
Pager operation is used to notify a user of a specific condition occurring in the I/NET
system. This condition is user-definable using message masking and priorities. The pager
is designed to receive a string of characters that are displayed on the recipients pager. This
string could represent a phone number or a recognizable warning code. You may call a
pager using the 78061 Tap emulation. The current version of I/NET adds several additional phone number characters for use with dial strings. Table 12 shows the additional
characters and their definitions.
Table 12. Pager Character Definition
Pager Character

Waits for five seconds, replaces the need for numerous commas.
;
Causes an immediate hang up, and should be used at the end of every
digital pager number dialed. (Not for use with a beeper.)
!
Issues a Hook flash, forcing the phone to go on-hook for 0.5 seconds.
W
Wait for a dial tone.
A pager differs from a beeper in that the pager sends a string of characters after a 5second period of silence. Also, beepers never use the semi-colon in their call string, while
digital pagers always require the semi-colon at the end of their call string. It is important
that you be familiar with your pager service and phone system so that you know of any
specific characters that may be required to place a successful call. For example, if you
were to enter a phone number for SWB MobileComm pagers in a 78061 Tap emulation,
using an ITT System 3100 PBX you would use the following format.
T9W8172731511#@123456;
The “T” at the beginning of the character string initiates tone dialing, the 9 obtains an
outside line. The “W” causes the Tap to wait for the modem to receive a dial tone before
dialing the pager service phone number. At the end of the phone number is a # sign that
causes this PBX to perform speed dialing, eliminating any unwanted delays.
The @ character causes the 78061 Tap emulation to wait five seconds and then sends the
code that will display on the recipient’s pager. The semi-colon causes the Tap to signal
the modem to immediately go on-hook, ending the call.
If your telephone system has no speed dial function, but has a period of silence exceeding
five seconds before the connection is made, add additional @ characters or commas to
prevent the Tap prematurely sending the pager code.
If the number being dialed is really a pager system (particularly a digital pager system),
the modem should be initialized with an X2 command. This will cause the modem to
ignore at least some of the tones presented by the digital pager system (that may be interpreted as busy) when the call is successful.
Note:
32
Some experimentation may be required to find the proper combination of characters to
make the pager call successful.
7780 DLCU
Installation Guide
Setup and Operation
Modem Switch Settings
The 7801 Integrated Dial and 78061 AD/AA emulated Tap functions require the use of
external modems. You must configure these modems for proper communication. For
modems without hardware switch settings (i.e., with software-controlled switch settings
only), a terminal emulator, such as Procom, or the communication software received
with your modem, must be used to issue command strings to the modem for proper
initialization. The modem setup requirements are described in the following paragraphs.
Auto Dial/Auto Answer
Note:
When using the emulated 78061 Tap function, the controller’s binary load (i.e., *.BIN file)
determines whether a synchronous or an asynchronous modem will be required for AD/AA
communication. For an I/NET 2000 binary load, the modem must be capable of asynchronous communication. For an I/NET revision 4.x or earlier binary load, the modem must be
capable of synchronous communication. Refer to the communications chapter in
TCON145, “I/NET Technical Reference Guide,” or TCON209, “I/NET 2000 Technical
Reference Guide,” for more information about AD/AA communications.
Ensure that all AD/AA Taps within your I/NET system are configured to use the same
communication protocol — either synchronous, or asynchronous. Mixing AD/AA protocols
will cause communication errors.
The optional RS232 expansion module (port P2) can be used as an interface for an
external Hayes-compatible auto-dial/auto-answer (AD/AA) modem. This configuration
is supported when the 7780 is set to emulate a 78061 site (LAN) Tap. Issue the following

Setup and Operation
Boot Record Firmware
The boot record firmware includes the following functions and capabilities:
✦
✦
✦
✦
basic self-test functions
communication capabilities (LAN and HHC address setting)
default control of outputs based on NOVRAM stored states
manual interrogate and control of I/O and firmware download
The firmware design and memory organization make sure the 7780 always receives a
complete firmware download, including revised LAN drivers.
Self-Test
When the microprocessor resets, a collection of memory tests are executed. If the
memory is corrupted, the controller restricts execution to the boot record firmware. An
alarm message is sent to the host PC and the appropriate LED lights up. If a hand-held
console is connected, it also receives an error message indicating that the controller firmware must be downloaded.
When the microprocessor begins a firmware download, it stops all control operations
and outputs are left in their last (latched) state. All commands coming over the LAN to
the controller during the download period are acknowledged with an error response and
ignored by the 7780.
Firmware Data Transfer
The communication packets used to carry firmware download data from the PC to the
controller pass through all upstream devices on the LAN or PC/modem port. In addition, the controller and intermediate devices allow memory array upload, including
firmware data. All I/NET Taps support firmware data transfer for the download/upload
functions.
