APPENDIX E — UPC OPEN CONTROLLER
The following section is used to configure the UPC Open. 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
1
network. Perform the following proce-
dure to assign an address:
1. If the UPC Open controller is powered, pull the screw termi-
nal connector from the controller's power terminals labeled
Gnd and HOT. The controller reads the address each time
power is applied to it.
2. Using the rotary switches (see Fig. G and H), set the control-
ler's address. Set the Tens (10's) switch to the tens digit of the
address, and set the Ones (1's) switch to the ones digit.
As an example in Fig. G, 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 com-
plete BACnet system in which the UPC Open controller is in-
stalled. 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
Instance of 16101 + 20 which would be a Device Instance of
1610120.
