Warning!! Do not connect signal and GND wire reversely.
If the buttons in JoyCon Explorer are too close each other, tune the Adjustment A/B.
5. LED
For external LED, a current limit resistor(usually 330ohm) must be connected in series. Without the
current limit resistor, LED burns out. (Black wire is Ground.) LED output is 5V.
6. Factory Reset
1. Short-circuit two reset points.
2. Connect USB.
7. Operational test
To check if CarPC JoyCon Exr works properly, short-circuit the two wires of a input channel without
connecting remote controls. The red indicator must goes to the left most side by short-circuit, and
returns to the right by open-circuit.
If the red indicator does not move, the CarPC JoyCon Exr is out of order.
Goes to the left most side.
Returns to the right side.

Check Setting and click Auto Detect. After auto-detection starts, press steering wheel control but-
tons one by one. After all the buttons are detected, click Auto Detect again to nish auto-detection.
Clear button clears all the buttons detected. You can tune the Resistor Range and Position manually
by putting the values in the edit boxes. Click Save/Apply after you change the values.
If the button bars are too close each other, tune the Adjustment A/B on the Board.
(Resistor range and position of the buttons are stored in the onboard memory of CarPC JoyCon Exr.)
Button bar turns to green when the controller button
is pressed.
2. Connect function
Drag-drop Button Bar to the keyboard keys(or HID remote controller buttons). Up to 5 keyboard
keys(or HID remote controller buttons) 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 on the
CTRL rst, ALT and DEL last.

The Long Button is kept pressed while L-Hold Time.
To Short Button and Long Button, put 1~254 in S-Hold Time or L-Hold Time.
Put 0 in S-Hold Time or L-Hold Time to disable Short Button or Long Button.
If Short Button or Long Button is disabled, Short Button or Long button is kept pressed while the
steering wheel button is pressed. This is useful when you need to keep a key pressed in volume con-
trol. (C, D channel support only Short Button and S-Hold Time. Hold Time value 1 is about 10ms.)
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

4. Programmable LED control
CarPC JoyCon Exr can control one onboard LED and two external LEDs.
If you want to control LED with a preset, check Control. If Control is not checked, this preset doesn’t

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 o by another pressing the button.
5. Toggle blink by a button : LED blinks periodically by press-
ing a button, and is turned o by another pressing a button.
6. On by a button, o after a period : LED is turned on by
pressing a button, and is turned o after a period automatically.
7. On by any button, o after a period : LED is turned on by pressing any button, and is turned o
after a period automatically.
Unit of Period is millisecond. In the blink mode(3, 5), turning on is one period and turning o is an-
other 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.

The presets are switched in sequence by Preset Up/Down Button. An application which is associ-
ated with the current preset in Application Launcher is closed by Close Button, Launched by Launch
Button. Congure the Preset Button of every preset le in the preset list in the same way(S-Hold
Time, L-Hold Time and Critical Time).

There is another way to switch the presets. You can switch 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. Congure the Preset Button of every preset le in
the preset list in the same way(S-Hold Time, L-Hold Time and Critical Time).
To use Close Button or Launch Button, check Use Launch Button or Use Close Button at Appli-
cation Launcher for each preset le.
