1.3.1
The “TC_link” Interface
The “TC_link” interface enables a communication between modules, even between modules
located in different frames. Electrically, it is based on an RS485 interface with a baud rate of
115,000. 256 modules at maximum are allowed to share one TC_link. External cables should
not exceed an overall length of 4000 feet (1200 m). Termination is provided at the fan
module (H1 or Q1 frame) and at the RC module (H3 frame), please refer to the related
chapters.
The communication protocol depends on the module and application.
