Recommended Tools

To connect a DH-485 network to additional devices, you need tools to strip
the shielded cable and to attach the cable to the AIC+ Advanced Interface
Converter. We recommend the following equipment (or equivalent):

DH-485 Communication Cable

The suggested DH-485 communication cable is either Belden #3106A or
#9842. The cable is jacketed and shielded with one or two twisted-wire pairs
and a drain wire.

One pair provides a balanced signal line and one additional wire is used for a
common reference line between all nodes on the network. The shield reduces
the effect of electrostatic noise from the industrial environment on network
communication.

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). However, two segments can be used to extend the DH-485
