Pinout and I/O specification

Signal connector pinout

Below are specified currently active cable variants.

S04

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

Pin detailed specifications

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.

Constant on

• The device turns on when power is applied and off when removed.

Internal HW configuration for this variant:

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

Flip-flop

• 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 disengaged.
• The device turns off once a voltage below 1V is applied to the power pin.
• It is also possible to turn off the device by FW.

Internal HW configuration for this variant:

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

Flip-flop with button

• 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 disengaged.
• 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

Activation input

• The device turns on once a voltage above 10V is permanently applied to the power pin.

• The device turns off once the voltage is removed from the power pin.

Internal HW configuration for this variant:

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

Scheme

Specification

Name	Function	Operating range	Maximum rating	Protection
KEY	power input for control electronics	0 .. 76 V		one-time fuse
POWER	power control input (switches device on/off), min. 10 V for on, max. 1 V for off	0 .. 76 V		high impedance
POWER GND	power input ground		100 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 analogue 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

Analogue inputs are not galvanically isolated from the power GND

Scheme

Specification

Name	Function	Operating range	Maximum rating
GPIO GND	GND, internally connected POWER GND		50 mA
+5V	5 V power supply		5 V / 50 mA
GPIO0	Input, max. 2% measurement error	0 .. 12 V	0 V .. 16 V
GPIO1	Input, max. 2% measurement error	0 .. 12 V	0 V .. 16 V
GPIO3	Input, max. 2% measurement error	0 .. 12 V	0 V .. 16 V

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.

Specification

Name	Function	Operating range	Maximum rating
LED GND	GND, isolated from POWER GND		50 mA
LED TURN	Input for Turn LED	0 .. 12 V	16 V
LED LIGHTS	Input for Hi-Beam LED	0 .. 12 V	16 V

CAN communication interface

Function

CAN communication interface is not galvanically isolated from the main POWER GND. The 120-ohm terminator can be activated/deactivated by the CAN terminator internal jumper.

Scheme

Specification

Number	Name	Function	Operating range	Maximum rating
1	CAN GND	GND, internally connected POWER GND		50 mA
2	CANL	CAN communication	0 - 5 V	+/- 70 V*
3	CANH	CAN communication	0 - 5 V	+/- 70 V*

Note *: +/- 70V between CANL and CANH only when CAN_GND is connected to neither of these two pins. Other possibilities have not been tested. Contact siliXcon for more information.
