Installation Instructions
The diagrams below show the location of the connectors for the MIDI-
2101 and the MIDI-2201. For proper operation, the units should
always be connected as shown.
MIDI-2101 Transmitter Considerations
The MIDI IN connector on this unit should be connected to the
standard MIDI signal to be transmitted over the fiber optic cable via a
standard 5 position 180° DIN connector cable. If a MIDI Thru output
signal is required, it may be obtained from the MIDI OUT connector
on the unit.
MIDI-2201 Receiver Considerations
The MIDI OUT connector on this unit should be connected to any
device that should receive the MIDI signal being transmitted over the
fiber optic cable. A standard 5 position 180° DIN connector cable
should be used
MIDI-2101/2201 Transmitter/Receiver Considerations
When the MIDI-2101 and MIDI 2201 units are connected with fiber
optic cable the result is a one-way transmission system. MIDI signals
applied to the MIDI IN connector of the MIDI-2101 transmitter will
appear at the MIDI OUT connector on the MIDI-2201

of one unit to the Rx
port of the other unit
with the appropriate
size fiber optic cable
