Before proceeding please check which Module-X model is being connected.

This chapter is about Module-X3 [GK_MX3]

 

Module-X3 with pigtail:

 

The Module-X comes with a pigtail existing of:

 

1.I/O cable

2.Ethernet cable

Module-X3 with dual pigtail

 

 

 

 

Wiring diagram of the Module-X3 - I/O cable

 

To connect the Symmetry controller, follow the schematic below:
 

•D0 → D0 terminal

•D1 → D1 terminal

•GND → Common ground
 

The Module X3 may come with different harness colour variants, but this has no impact on the Wiegand wiring.

 

The Wiegand signal wires (D0, D1, and GND) are consistently coloured across both versions, so you can safely follow the standard colour coding in the schematic.

If other wires differ in colour, this is expected and does not affect the Wiegand connection.

Below are the two tables for your reference.
