APPENDIX D — 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
us
er 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
Devi
ce 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.
