Signal connector pinout​

Below are specified currently active cable variants.

This variant is equipped with two cables ending with JST JWPF connectors. Both cables have a length of 400 mm. The first cable is designed as an interface connection to a siliXcon controller. The second cable should be used as an interface for external components (map switch and 12V system).

Cable one​

  • The cable length is 400 mm
  • The power connector matches with the controller's Power, Key and GND pins
  • CAN connector matches with controller's CANL, CANH, and CAN GND pins

Power circuit​

Function​

The power circuit provides power to the display. The KEY input is designed to be connected to the battery voltage through the controller's KEY pin. Power to the internal SMPS (Switched-Mode Power Supply) is controlled by an electronic switch. There are several options for powering on/off, which are described below.

  • The device turns on once a voltage above 10V is applied to the power pin. The latching function of the flip-flop ensures that it remains turned on even when the voltage is disconnected.
  • The device can be alternatively turned on by a short press of the button #1.
  • The device turns off once a voltage below 1V is applied to the power pin .
  • The device can be alternatively turned off by a long press of the button #1.
  • It is also possible to turn off the device by FW.
info

All the other devices connected to the POWER pin also receive the powering signal - The device could turn on/off other devices.

Internal HW configuration for this variant:

  • Key resistor - Removed
  • Flip-flop - Attached
  • Powering by button - Attached

info

One of these jumpers must be enabled - S101 or S102. Otherwise, display will not turn on.

POWER GNDpower input ground100 mA
warning

Voltage between 1 V and 10 V is not allowed, because the device is in a non-defined state and could be damaged in such a situation.

Analog inputs​

Function​

The display is equipped with three analog inputs that can be used to connect external accessories. The reference potential is shared with the main GND. +5V source for driving external components is also available. The operating range of the inputs is 0 - 12 V.

warning

Analog inputs are not galvanically isolated from the power GND

12V inputs​

Function​

The display can process 12V signals for the Turn and Hi-beam light indicator LEDs. These inputs are galvanically isolated from the main Power GND. It is also possible to control the LEDs by firmware (FW) if the Turn LED by FW respectively Light LED by FW configuration is selected.

info

The 12V LED inputs are galvanically isolated from the POWER GND.
