Appendix B: Bi-Directional Cable Schematic
The important thing to remember when making these cables is that standard MIDI cables only use pins 4 and 5 for MIDI
traffic.
To make the MIDIjet Pros able to function with regular cables, pins 4 and 5 on the transmitter (black) unit, are MIDI In and
on the receiver (grey/white) unit, pins 4 and 5 are MIDI out.
So then pins 1 and 3 on the transmitter are MIDI out and 1 and 3 on the receiver are MIDI in
