Appendix A
Setting Up the DH-485 Network
A–10
Installing the DH-485 Communication Cable
The communication cable consists of a number of cable segments
daisy–chained together. The total length of the cable segments cannot
exceed 1219 m (4000 ft).
When cutting cable segments, make them long enough to route them from
one link coupler to the next with sufficient slack to prevent strain on the
connector. Allow enough extra cable to prevent chafing and kinking in the
cable.
