Configuring the Symbio 800 for Communications
Communication Protocols Supported
The Symbio 800 controller supports the following communication protocols:
•
BACnet TP (Default is 76,800 bps. 19,200, 38,400, 76,800 bps are available.)
•
BACnet / Air-Fi
•
BACnet / IP (Ethernet P ort 1)
•
Modbus RTU
•
Modbus TCP
•
LON via the USB U60 adapter
All Protocols can be configured through the Symbio UI.
N
No

•
Lontalk and Modbus may not be an option on all equipment types and configurations.
•
The Symbio 800 controller only supports one communication protocol at a time.
BACnet TP — Setting Addresses Using Rotary Switches
There are three rotary switches on the front of the Symbio 800 for the purpose of defining a
three-digit address when it is installed on a BACnet communications network. The three-digit
address setting is used as both the rotary switch value and the BACnet device ID.
For Trane BACnet TP systems, the rotary switch value must be between 1 and 127. Although
“0,0,0,” is a valid BACnet address, Trane reserves this address for the Tracer SC+ controller. All
device addresses on the BACnet TP link must be unique.
•
Before powering up the Symbio 800, set the rotary switch value as shown in the following
figure.
•
If the Symbio 800 was previously powered up, do the following if you wish to make changes:
–
Make the preferred changes to the rotary switch value as illustrated in .
–
Power down the Symbio 800; when re-powered the new rotary switch value should be
active.
•
For controllers that are connected through BACnet/IP, or wireless via ZigBee™, valid unit
controller rotary switch values can range from 001 to 999.
