Introduction
The TCF-142-RM Series slide-in modules are serial-to-fiber converters that work with the TRC-190 chassis. The modules convert from the RS-232, RS-422, or RS-485 signal to a fiber-optic signal.

Automatic Baudrate Detection
The TCF-142-RM Series can automatically detect the serial baudrate. This is an extremely convenient feature. Even if a device’s baudrate is changed, the signal will still be transmitted through the media converter without any problem.
