To prevent confusion when installing the communication cable, cut back the white with blue stripe wire
immediately after the the insulation jacket is removed. This wire is not used by DH-485.
Grounding and T erminating the DH-485 Network
Only one connector at the end of the link must have Terminals 1 and 2
jumpered together. This provides an earth ground connection for the shield
of the communication cable.
Both ends of the network must have Terminals 5 and 6 jumpered together.
This connects the termination impedance (of 120Ω) that is built into each
AIC+ as required by the DH-485 specification.
