RS-485 Network Wiring

Network wiring conforms to 3-wire RS-485 electrical specifi cations. Units connected in the network can be wired using one unit as a “hub” or by wiring from one unit to the next in “daisy-chain” fashion. See the fi gures for wiring options.

•Use Belden 9925 or Carol C0600 shielded cable or equivalent. Maximum wire run distance is 4000 feet.

✦NOTE: Be sure to connect the cable’s shield to one of the GND terminals.

Network Wiring with Hub

1.Mount and install the units for the network.

2.Choose one unit to be the Network Hub. Usually this would be a centrally located or “master” unit.

3.Route 3-conductor shielded cable from the hub unit to one of the other units. Repeat this step to connect the hub unit to each of the other units.

4.Connect the 3-conductor cable to each unit’s NETWORK terminals.

Network “Daisy-chain” Wiring

1.Mount and install the units for the network.

2.Route 3-conductor shielded cable from one unit to the next unit until there is cabling run to all of the units.

3.Connect the 3-conductor cable to each unit’s NETWORK terminals.
