Setting the Address

The three (3) rotary address dials on the Symbio 210 serve one or two purposes depending upon
the network: they are always used for the MAC Address, which is sometimes all or part of the
BACnet Device ID.
Figure 5.
MAC Address
The MAC Address is required by the RS-485 communication protocol on which BACnet operates.
Valid MAC addresses are 001 to 127 for BACnet.
Important:
BACnet Device ID
The BACnet Device ID is required by the BACnet network. Each device must have a unique number
from 001 to 4094302.
18
Use 18 AWG shielded communication wire for BACnet MS/TP installations.
Limit BACnet MS/TP wiring links to 4,000 ft. There is a maximum of 60 devices per link.
Note: Three (3) BACnet MS/TP links are available on the Tracer SC+.
Connect the BACnet link to the Symbio 210 controller terminals labeled Link on the lower-right
corner of the Symbio 210. Incoming wires can be connected to the first two terminals, and the
outgoing wires can be connected to the second set of terminals, so there is only one wire per
termination. For more details, refer to the BACnet Best Practices and Troubleshooting Guide
(BAS-SVX51-EN).

x100 x10 x1
Each device on the link must have a unique MAC Address/Device ID. A duplicate
address or a 000 address setting will interrupt communications and cause the Tracer
SC device installation process to fail.
Use a 1/8 in. (3 mm) flathead screwdriver
to set rotary switches. Switches rotate
in either direction.
