Port 2: RS-232 or MIDI
Port 2 is factory configured as a MIDI port, but can be reconfigured as an RS-
232C serial port. For RS-232 use the connections are provided on a male DB-9
connector. For MIDI, they are provided on three 5-pin DIN connectors. When
configured for MIDI, MIDI Input is received by the MIDI IN port, and MIDI
Output is sent out the MIDI OUT port. The MIDI Thru port echoes the data
received on MIDI IN.
