The MA 50 has a built-in serial RS 232 PC-interface for data transfer to a
connected PC. The serial cable to connect the MA 50 with the PC should be
a normal, non twisted 9-pin extension cable. It has a male and a female
connector and all wires are direct 1:1 connected. It is also sold as monitor
extension cable.
