Grounding and Terminating 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.
