INSTALLATION
Wiring - continued
Prerequisite: A nearby earth grounding point.
1. Install the included earth ground wire (1) to the controller’s earth ground spade lug (2), and terminate the
other end to a nearby earth ground (3).
2. Unplug the controller’s 2-position power connector (4) and terminate a 24 V supply source (5) to the connec-
tor. Leave connector unplugged for now.
RS485 Wiring
On the controller’s top side, a single, non-isolated, RS485 port provides connection to IO-R-34 module or to
other RS-485 devices (NRIO, BACnet MS/TP, MODBUS). Do not use this port to connect to other controllers.
Use shielded, twisted-pair, 18-22 AWG cabling to wire in a continuous multidrop fashion to other RS485 devices:
“minus to minus”, “plus to plus,” and “shield to shield”. 10K bias resistors are permanently connected. There is no
built in termination resistor. Maximum total cable length is 1,000 feet (304.8 meters).
Connect the shield wire to earth ground at the MS-E10 Controller end only. The following image shows example
wiring.

NOTE: Do not mix an IO-R-34 with other types of RS485 devices on the same RS485 trunk.
NOTE: RS485 devices on the same network should use the same protocol and baud rate. Up to 50 total external points across
3 external devices are supported.
