ROBERTS GORDON CORAYVAC
Wire Specifications
18–28 AWG; twisted pair preferable
50' (15.24 m) maximum length
Note: Do not power the device from the same
transformer that powers the I/O Pro 812u controller.
8. Turn on power to control board.
Verify accuracy of the following:
• Baud rate DIP switches 4 and 5
• Protocol DIP switches 6, 7, and 8 jumper set cor-
rectly to EIA-232 or EIA-485
• Proper connection wiring
• Unique rotary address switches 1 – 99.
• If controllers have duplicate addresses, network
communication can be lost.
NOTES: If RX LED is solid, then the terminations are
incorrect. If the network has greater than 32 devices
or exceeds 2000' (610 m) a Repeater should be
installed. If a controller begins or ends a network
segment, a terminating resistor may be needed. The
controller recognizes physical changes (DIP
switches, rotary switches, and jumpers) upon power
up.
12.6.3 To set up the Modulating Controller for
Modbus over IP
1. Turn off power to control board.
2. Check the communications wiring for shorts and

grounds.
3. Connect Port E1 to the third-party device.
Note: Port E1 will still be capable of BACnet
communication.
Wiring Specifications
• Maximum wire length, 328' (100 m)
• Use one of the following CAT5 or higher Ethernet
cables:
o
o
Note: Use the same polarity throughout the network
segment.
4. Turn on the power to the control board.
Verify accuracy of the following:
• Proper connection wiring.
• Confirm the IP address, subnet mask, and default
gateway address for your router with the manufac-
turer.
• Confirm the correct IP address through the Touch
screen.
12.7 To set up the Modulating Controller for N2
on Port 1
1. Turn off power to the control board.
2. Using the rotary switches, set the controller's
A cross-over cable to connect the
controller directly to the third-party
device
A straight-through cable to connect
the controller to a hub or switch, and a
second straight-through cable to
connect the hub or switch to the third-
party device
