Set Controller Address —
The UC Open XP control-
ler’s rotary switches determine the UC open XP’s MAC ad-
dress when it is placed on a BACnet MS/TP network. The rota-
ry switches define the MAC address portion of the device’s
BACnet address, which is composed of the network address
and MAC address.
Perform the following procedure to assign an address:
1. Turn off the UPC Open XP power switch.
2. Using the rotary switches, set the controller 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. For example, if
the controller address is 25, point the arrow on the 10’s
switch to 2 and the aroow on the 1’s switch to 5. See Fig.
7.
3. Turn on the UPC Open XP power switch. The controller
reads the address each time power is applied.
50XJ Variable Frequency Drive (VFD) Control
