Watlow EZ-ZONE RUI/Gateway - Manual (Page 10)

Ó
Warning:
Use National Electric
(NEC) or other country-
specific standard wiring
and safety practices when
wiring and connecting
this controller to a power
source and to electrical
sensors or peripheral de-
vices. Failure to do so may
result in damage to equip-
ment and property, and/or
injury or loss of life.

• Do not route network
wires with power wires.
• Connect one Ethernet
cable per device to a
10/100 mbps Ethernet
switch. Both Modbus ®
TCP and EtherNet/IP™
are available on the
network.
Note:
When changing the fixed IP address on the RUI cycle module power for new address to take ef-
fect.

• 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 Digital Ground
to the common ter-
minal of the EIA-485
port.
• Do not route network
wires with power
wires. Connect net-
work wires in daisy-
chain fashion when
connecting multiple
devices in a network.
• A termination resistor
should be used if this
controller is the last
one on the network.
• If using a 150 Ω cable
Watlow provides inter-
nal termination. Place
a jumper across pins
trB and B and trA and
A.
• If external termina-
tion is to be used with
a 150 Ω cable place a
390 Ω resistor across
pins VP and B, a 220
Ω resistor across pins
B and A, and lastly,
place a 390 Ω resistor
across pins DG and A.
• Do not connect more
than 32 EZ-ZONE
devices on any given
segment.
• Maximum EIA-485
network length: 1,200
meters (4,000 feet)
• 1/8th unit load on
EIA-485 bus.
