Hello, I am currently using a Questtel SDI-over-fiber extender with RS-485 data for serial control. I have recently switched to a Canon CR-N300 camera , which provides an RS-422 interface for control. Given the differences between RS-485 (2-wire, half-duplex) and RS-422 (4-wire, full-duplex), I would like to confirm whether it is feasible to implement an RS-485 to RS-422 conversion within the signal path and maintain reliable communication over the existing fiber extender. Specifically, can a protocol-transparent hardware converter be used in this scenario? Any recommendations on compatible solutions for integrating RS-422 control over the current infrastructure would be greatly appreciated.
