The following section is used to configure the UPC Open con-
troller. The UPC Open controller is mounted in a separate en-
closure 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-
1
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
labeled Gnd and HOT. The controller reads the address
each time power is applied to it.
2.
Using the rotary switches (see Fig. H and I), 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. H, 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 ad-
dress. This Device Instance MUST be unique for the complete
BACnet 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
fault, a MAC address of 20 will result in a Device Instance of
16101 + 20, which would be a Device Instance of 1610120.
