Gotham DMX512 / RDM Field Installation Manual

Gotham DMX512 / RDM Field Installation Manual
October 2014
Description
The Gotham Incito downlighting family utilize DMX512 protocol via a native DMX driver (eldoLED
POWERdrive) over twisted pair (120ohm), shielded recommended, and has the capability to
communicate with the lighting controller (processor, light board, controller, etc.) via RDM (Remote
Device Management). System has been designed & tested for signal integrity with all downlight &
cylinder mounting methods.
The Remote Device Management Protocol (RDM) permits intelligent bi-directional
communication between devices from multiple manufacturers utilizing a modified DMX512 data
link. RDM is an EF 1.0 implementation of ANSI E1.11. RDM permits a console or other
controlling device to discover and then configure, monitor, and manage intermediate and enddevices connected through a DMX512 network. RDM provides for intelligent control of devices on
a DMX512 network, which has not been previously available outside of proprietary networks.
This standard specifies: the physical layer and timings, device discovery process and algorithms,
message structure and communication.

Protocols Supported
Gotham luminaires with eldoLED DMX POWERdrive driver support the current DMX standard ANSI
E1.11 DMX512-A and is backwards compatible to USITT DMX512 (1990). Also supported is ANSI
E1.20 RDM (Remote Device Management).
Installation
Specifications
 Default DMX512 address – 001 (Changeable only via RDM)
 8-bit interpolation (internal smoothing algorithm for long fades)
 1-slot footprint
 Square Law Curve
 DMX start-up – 20% output on power up until DMX signal discovered
 RDM ID Behavior – steady flash
 DMX fail – Hold last look forever
 Device mode description – Gotham
Network Setup
 Use the pinout configuration on page 6 to connect to the lighting controller.
 Including the DMX512 source, a maximum of 30 Incitos per daisy chain is
allowed. Consult factory for applications requiring more than 30 Incitos per run.
Note: One universe fed into an opto-splitter creates multiple runs. See Figure 2
 DMX is a 3-wire connection. Signal common must be connected and grounded at
the controller.
 Cable needs to meet the ANSI/TIA/EIA-485 standard for DMX-512 and have
nominal characteristic impedance of 120 Ohms.
 Using the appropriate category cable, daisy chain between luminaires as shown in
Figure 2. Note: No T-TAPS, STARS (except by an RDM opto-splitter), splices, or
Ys allowed.
 A termination resistor is included with each luminaire. Ensure the termination
resistor is installed into the last luminaire in the daisy chain. If this component is
not installed the luminaires may exhibit erratic/intermittent behavior.
 Several fixtures may have the same address if desired for zoning.
 1000 feet is the maximum cable distance to the furthest luminaire from the splitter
per segment.
 Addressing via RDM only. Recommended RDM devices include:
 Axion Connectivity DXT enclosure & a computer running Pathport
Manager 5.2 software
 Goddard Design - DMXter4A RDMtm
 Swisson - RDM Controller / DMX Tester - XMT-350

Notes:
1.
Do not utilize T-TAPS, STARS or Y’s. If a STAR wiring
configuration is needed then an opto-splitter is
required.
2.
Ensure termination resistor is utilized at the end of
each daisy chain.

DMX512/RDM Pinout Configuration (ANSI E1.11)
*Shielded, twisted pair (120ohm) recommended cable specifications.
If using CAT5, CAT5E, CAT6 cable recommend splicing into XLR cable
from console or utilize 5 pin XLR to RJ45 adaptor.

Glossary of Terms
Lighting controller: is an electronic device used in theatrical lighting design to control multiple
lights at once. All lighting control consoles can control dimmers which control the intensity of the
lights. A lighting controller can be a console type processor such as the Pathway CognitoTM or a
wall controller such as an FrescoTM.
DMX512: is a standard for digital communication networks that are commonly used to control
stage lighting and effects.
Slot: is a sequentially numbered byte in a DMX512 packet. Slot 0 is the START Code. Slots 1
through 512 are data slots.
Slot Footprint: is the number of data slots used by a product in its operation. Note: A 24 way
dimmer rack may have a footprint of 24, it may be more if some slots are used to provide
additional control functions using NULL START Code packets. Automated luminaires usually
require a Slot Footprint of greater than one.
Universe: is a DMX512 data link originating from a single DMX512 source. DMX512 data slots
comprises a single universe.
Daisy chain: is a wiring scheme in which multiple devices are wired together in series.
RDM (Remote Device Management): is a protocol enhancement to USITT DMX512 that allows
bi-directional communication between a lighting or system controller and attached RDM
compliant devices over a standard DMX line. This protocol will allow configuration, status
monitoring, and management of these devices in such a way that does not disturb the normal
operation of standard DMX512 devices that do not recognize the RDM protocol.
Termination resistor: is used when you are using several DMX luminaires on a single DMX line
(Universe). It removes noise and flickering on the DMX line which improves the reliability of the
DMX system. The termination resistor will match the cable impedance.
Square Law Curve: is a dimming curve most closely correlating to that of traditional halogen
dimming performance
•DMX Fail: This parameter defines the behavior of the device when the DMX512 control signal is
lost.
•DMX Startup: This parameter defines the behavior of the device when it starts up and the
DMX512 control signal is absent.
