After all the buttons are detected, click “Auto Detect” again to finish auto-detection and click “Save/Apply” to download the steeing to CPJexc. “Clear” button clears all the buttons detected. (Detected buttons are stored in the onboard memory of CPJexc.) 5. Connecting a button to the hotkey Drag-drop Button Bar to the keyboard keys(or HID remote controller buttons). Up to 5 can be connected to one button. Drag-drop sequence is same with the keyboard key stroke sequence. For example, if you want a button to generate hotkey CTRL+ALT+DEL, drag-drop the Button Bar on the CTRL first, ALT next and DEL last. Drag-Drop CarPC JoyCon Exc ChangJack.Com 15 6. Disconnecting a buttons from the function Right-click the Button Bar or keyboard key(or HID remote controller button) and click an item in the drop down menu. Or drag-drop the Button Bar to the connected keyboard key(or HID remote controller button) again. 7. Save / Restore Preset Save the hotkeys and configuration as a preset file(.prs) by Save(Save As) button. Restore the hotkeys and configuration by Open Preset button or by double-clicking a preset file(.prs) or by drag-drop of a preset file(.prs) to the preset edit view.

Save As Save Open Preset New Preset Clear Drag-Drop CarPC JoyCon Exc ChangJack.Com 16 Extended Button Setting 1. Short Button and Long Button CPJexc supports two separated functions for one steering wheel remote control button. The two functions are Short Button and Long Button. Short Button is generated when the remote control button is pressed or released before Critical Time. Long Button is generated when the remote control button is released after Critical Time. To use Long Button, set the Critical Time over than 0, then Long Button Bar will appear above the Short Button bar. Long Button Short Button 2. Separate Short and Long button When you want to generate only the long button, the short button is required not to be generated immediately by pressing the remote control button. Put 1~254 in S-Hold Time. The short button is generated when the button is released before Critical Time while S-Hold Time. The long button is generated when the button is released after Critical Time while L-Hold Time. Hold Time value 1 is about 10ms, so Hold Time value 254 is about 2540ms(2.54s). Hold Time 0 means that the button keeps being pressed while you keep pressing the remote control button. This is useful when you need to keep a key pressed in volume control. (C, D channel support only Short Button and S-Hold Time.) 3. Toggle Button If the Hold Time of a button is 255, the button is toggled. This is useful when a keyboard key need to be stroked while SHIFT, CTRL, or ALT keys are kept pressed. (For example, ALT+TAB or Window+TAB) CarPC JoyCon Exc ChangJack.Com 17 4. Cyclic Button You can rotate buttons by checking Cyclic Button. The cyclic buttons rotate by pressing any checked button. For example in the next picture, when you press A1(or A2 or A3 or A4), button works A1->A2->A3->A4->A1->A2.... 5. Programmable LED control CPJexc can control one onboard LED and two external LEDs. If you want to control LED with the current preset, check Control in the LED tab. If Control is not checked, this preset doesn’t control LED and LED keeps previous configuration. If Reverse is checked, On Off is reversed. If Turn Off on Sleep is checked, LED is turned off when the PC goes into sleep mode. LED control has 8 modes. 0. Always On : LED is turned on always 1. Always Off : LED is turned off always 2. On by a button : LED is turned on while a button is pressed. 3. Blink by a button : LED blinks periodically while a button is pressed. 4. Toggle by a button : LED is turned on by pressing a button, and is turned off by another pressing the button. 5. Toggle blink by a button : LED blinks periodically by pressing a button, and is turned off by another pressing a button. 6. On by a button, off after a period : LED is turned on by pressing a button, and is turned off after a period automatically. 7. On by any button, off after a period : LED is turned on by pressing any button, and is turned off after a period automatically. Unit of Period is millisecond. In the blink mode(3, 5), turning on is one period and turning off is another period. For example, if the Period is 500(ms), LED is turned on every 1 second(1000ms). To assign a button to LED, drag-drop a button to a LED. CarPC JoyCon Exc ChangJack.Com 18 Preset Switching A preset can be downloaded to CPJexc by Preset Button automatically, it is useful when you need to change steering wheel remote control’s configuration while driving. 1. Preset List Drag Drop preset files on the list of Preset tab. Preset is switched with the sequence of this list. Drag-Drop 2. Preset Button The presets are switched in sequence by Preset Up/Down Button. An application which is associated with the current preset in Application Launcher is closed by Close Button, Launched by Launch Button. Configure the Preset Button of every preset file in the preset list in the same way(S-Hold Time, L-Hold Time and Critical Time). CarPC JoyCon Exc ChangJack.Com 19 There is another way to switch the presets. You can download a preset and launch an application directly not in sequence with Preset Button in the preset list. The application which is associated with the preset is closed by Close Button in the Preset List. Configure the Preset Button of every preset file in the preset list in the same way(S-Hold Time, L-Hold Time and Critical Time). 3. Application Launcher An application can be launched and popped up when Preset is switched. Drag-drop (.exe) file(or shortcut file) or double-click current running application in the list box. Name is spoken when the application is launching. If the application is not running, the application is launched. If the application is already running, the application pops up. If the Track top window is checked, Preset is automatically switched by the top window. 4. Start option Check Start with Windows to run JoyCon Explorer when Windows starts. Check 1st Preset when Starting to run the first preset in the preset list when the JoyCon Explorer starts. “Run Preset” means to launch or pop up an application with opening an preset). Check Open this Preset when Starting and drag-drop a preset on the edit box, to open the preset when JoyCon Explorer starts.
