Wiring a Serial EIA-485 Network
Do not route network wires with power wires. Con-
nect network wires in daisy-chain fashion when con-
necting multiple devices in a network.
A termination resistor may be required. Place a
120 Ω resistor across T+/R+ and T-/R- of the last con-
troller on a on a network.
Note:
Termination resistors when used, require a termina-
tion resistor at both ends of the network.
A network using Watlow's Standard Bus and an RUI/Gateway .
