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.

Notes:
When using EtherNet/IP the RMA module supports implicit and unconnected explicit messaging.
