Integration Into Building Management System (Bms) - Roberts Gorden CORAYVAC Installation Manual

Each control board on the network must have a
unique MAC address. The IP address must be
unique on the Ethernet network. The default IP
address can be used or a custom IP address can be
assigned. In addition to these two addresses, the IP
network number must be set for each controller. Use
the touchscreen provided to set these values.
The touchscreen communicates between controllers
over an MS/TP network with network number 100.
This must not be changed. The MS/TP network
number is important for the broadcasting of Outside
Air Temperature.
Create the MS/TP network between controllers. See
Page 40, Section 5.4. Access the controller you wish
to program through the touchscreen home menu.
See Page 45, Section 5.8 for help.
Default IP Address
IP address: 192.168.168.x where x is the MAC
address
Subnet mask: 255.255.255.0
To set the MAC address on the controller, use the
rotary switches located just above the HOA switches
on the control board. Refer to the above photo. The
switches are for the 1's place and the 10's place
respectively.
Note: Changes to the switches are recognized only
after power has been cycled to the control board. To
properly cycle power to the control board and touch-
screen, turn the circuit breaker located on the termi-
nal strip above the control board off for 10 seconds
before turning it back on. To use the default IP
address, ensure DIP switch 2 is in the off position.
Custom IP Address
Assign a custom IP address using the touchscreen
located on the central control panel provided. Open
the local Menu at the bottom right of the screen scroll
to the bottom, and select IP. This opens the IP menu.
IP can be reached on Menu  IP
Enter an IP address in the Assigned IP Address
field. Click save.
On the control board, turn DIP switch 2 on. All other
DIP switches should be off. See Page 14, Figure 6 in
manual for help locating the DIP switch.
Cycle power to the control board. Allow the touch-
screen time to reload information from the board,
then navigate back to the IP menu. The Current IP
Address should now be populated with the assigned
address.
IP Network Number
Finally, set the IP network number to a value other
than 100 (i.e. 101). The IP network number must be
set for each controller with an Ethernet connection.
5.3 Integration into Building Management System
(BMS)
The controller (I/O Pro 812U) is capable of communi-
cating with a foreign BMS. Connection can be made
easily by connecting the controller to BMS by the 2-
