Installing the DH 485 Cable
The DH-485 cable consists of a number of daisy-chained segments. The
total length of the combined segments must not exceed 4,000 feet. Cut the
cable segments long enough to route from one node to the next, allowing
sufficient slack to prevent strain on the connectors. Provide strain relief
for the cable after it is plugged in to prevent the cable wires from breaking.
