MS/TP MAC Address
Each device on a BACnet MS/TP network must be assigned a unique physical address. This is
referred to as the Media Access Control (MAC) address. The BACnet Standard defines the valid
address range of a MS/TP master device as zero (0) to 127. All Trane devices are master devices.
When a Tracer SC device is present on the MS/TP network, Trane restricts the use of the zero (0)
MAC address. This address is assigned to the Tracer SC and cannot be changed. All other
BACnet MS/TP master devices, including the UC600, must have a MAC addresses within the
range of 1 to 127. The three (3) rotary switches on the front of the UC600 device are used to set
the MAC address.
Failure to assign a unique address to each device on the network will cause network
communication failure.
