Use MTCHIO RS422 without Mykerinos

You can use the RS422 port of the MTCHIO without any Mykerinos connected.
Note that the other connectors, Video Ref, Wordclocka and LTC can only work with a Mykerinos.

To be able to use MTCHIO 9 pin module without Mykerinos, you must remove the jumper from JP3 ( 5V from the Mykerinos board through the 16pins ribbon cable connected to the Video/TC header ) and put it on JP2 (5V from the PC power supply through a Molex connector)

See the detailed picture below to locate exactly these I/Os:

 

WARNING: Never connect both JP2 and JP3 at the same time.
