Tracer BACnet Terminator
A Tracer BACnet
®
terminator is placed at the end of each communication link in order to
decrease communication signal degradation. Refer to the
BACnet

Wiring Best Practices and
Troubleshooting Guide,
(BAS-SVX51).

LonTalk Network Configuration
The Tracer USB LonTalk module (U60) connects to any one of the four USB ports on the Symbio
800 controller. It is configured from the factory to the default DSN A (ZL-255-004) and DSN B (11-
255- 004) on power up by the Symbio 800 controller. The Rover service tool is used to configure
the DSNs.
Modbus TCP/RTU
The Symbio 800 controller can be configured to be a Modbus RTU or Modbus TCP server.
Common applications using Symbio 800 Modbus communications are to communicate to an
industrial front end or SCADA (Supervisory Control and Data Acquisition).
Modbus RTU uses 2-wire TIA/EIA-485 communications on the Symbio 800 P1 link. The additional
+ and – terminals are used to make it easier to daisy chain wire additional Modbus TIA/EIA-485
devices. As per Modbus TIA/EIA communications, only one Modbus RTU client can communicate
to the Symbio 800 controller.
Modbus TCP uses Ethernet communications on the Ethernet port 1 of the Symbio 800 controller.
Multiple Modbus TCP clients can communicate to the Symbio 800 controller.

Setting Up a Trane Wi-Fi Network
Trane Wi-Fi modules are supported by Symbio 800 and setup via Symbio UI. Wi-Fi modules only
operate as an access point. This can be useful if connecting to the Symbio 800 via Tracer TU or
Symbio UI wirelessly.
