EtherNet/IP™ and Modbus TCP communica-

tions to connect with a 10/100 switch.

• Do not route network wires with power

wires.

• Connect one Ethernet cable per controller

to a 10/100 mbps Ethernet switch. Both

Modbus TCP and EtherNet/IP™ are avail-

able on the network.

• Wire T-/R- to the A terminal of

the EIA-485 port.

• Wire T+/R+ to the B terminal of

the EIA-485 port.

• Wire common to the common

terminal of the EIA-485 port.

• Do not route network wires

with power wires. Connect net-

work wires in daisy-chain fash-

ion when connecting multiple

devices in a network.

• A termination resistor is re-

quired. Place a 120 Ω resistor

across T+/R+ and T-/R- of last

controller on network.

• Maximum number of devices on

a Modbus network is 247.

• maximum network length:

1,200 meters (4,000 feet)

• maximum EIA-232 network

length: 15 meters (50 feet)

• Do not connect more than one

EZ-ZONE RM controller on an

EIA-232 network.

• Do not wire to both the EIA-485

and the EIA-232 pins at the

same time.

• Two EIA-485 terminals of T/R

are provided to assist in daisy-

chain wiring.

• 1/8th unit load on EIA-485 bus.
