APPENDIX B — OPTIONAL BACNET COMMUNICATIONS WIRING

Optional BACnet* Communications Wiring —

The following section is used to configure the UPC Open con- troller which is used when the BACnet communications option is selected. The UPC Open controller is mounted in a separate enclosure below the main control box.

TO ADDRESS THE UPC OPEN CONTROLLER — The user must give the UPC Open controller an address that is unique on the BACnet network. Perform the following proce- dure to assign an address:

1.If the UPC Open controller is powered, pull the screw ter- minal connector from the controller's power terminals la- beled Gnd and HOT. The controller reads the address each time power is applied to it.

2.Using the rotary switches (see Fig. A and B), set the con- troller's address. Set the Tens (10's) switch to the tens dig- it of the address, and set the Ones (1's) switch to the ones digit.

As an example in Fig. B, if the controller’s address is 25, point the arrow on the Tens (10's) switch to 2 and the arrow on the Ones (1's) switch to 5.

BACNET DEVICE INSTANCE ADDRESS — The UPC Open controller also has a BACnet Device Instance address. This Device Instance MUST be unique for the complete BAC- net system in which the UPC Open controller is installed. The Device Instance is auto generated by default and is derived by adding the MAC address to the end of the Network Number. The Network Number of a new UPC Open controller is 16101, but it can be changed using i-Vu®Tools or BACView device. By default, a MAC address of 20 will result in a Device In- stance of 16101 + 20 which would be a Device Instance of 1610120.
