Appendix F:
Grounding the
Communication Cable
In this appendix, we cover grounding the DX3 / DXi communication cable.
Adequate grounding for the communication cable is essential.
The cable connecting each DX3 / DXi controller (part number EV-CAB-COMM)
contains one twisted pair and one mesh outer shield. By exposing the twisting the
mesh shield (see Prepping the Communications Cable below), it can serve as the
ground connection between controllers. The ground connection can be attached to:
• the GND input on the DX Comm board
(Method 1 - one ground wire only)
• grounding screw/s mounted in the chassis
(Methods 2 and 3).
1) Slice outer
jacket of COM
wire to reveal
wire mesh.
2) Trim away outer
layer.

3) Trim inner
jacket to expose
copper and
tinned wires.
