Addressing the MPC Open XP
The MPC Open XP's two rotary switches determine its MAC address when it is placed on a BACnet MS/TP network.
The rotary switches define the MAC address portion of the device's BACnet address, which is composed of the
network address and the MAC address.
1
Turn on the controller's power.
2
Using the rotary switches, set the controller'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.
EXAMPLE
If the controller’s address is 25, point the arrow on the
Tens
(
10's

the
Ones
(
