3.3 COMMUNICATION
3. 3. 1 Port 1 configuration
The TR80 wall module is a Modbus slave on its port 1.
3. 3. 2 Port 2 configuration
Port 2 on the TR80 wall module has two functions. It can act as a repeater between a master
controller and a downstream DALI64 sensor. Secondly, it can send basic light level and scene
commands of the user directly to a DALI64MOD sensor. These two functions do not conflict,
they can be used simultaneously.
*
Baud rate and parity enumerations are same as
Port 1 configuration.
If a DALI64 sensor is connected on port2, the DALI64 device's slave address must be set on
configuration parameter 12.
