USB to RS-232 adapter
Since many modern motherboards do not have spare RS-232 headers MTCHIO is generally supplied from
the factory already connected to an on-board USB header via an included USB to RS-232 adapter and
cable.
The RS-232
USB converter transforms RS-232 signals to/from USB signals. It has been developed to
allow the MTCHIO RS-422 functionality to be retained with motherboards lacking an internal RS-232
connector. This converter is USB 2.0 compliant (12Mbps).
The RS-232
USB module must be inserted into the
J1
connector.
Warning!
Due to the small dimensions of the RS-232 connector, it is possible to incorrectly
insert the plug. Please ensure it is correctly aligned as in this picture:
