CAUTION ! AVOID DIRECT EXPOSURE TO BEAM.
All -7,-8, and -9 Models use laser diodes. These solid-state laser diodes
are located in the optical ports of these units. Laser diodes produce
invisible radiation that may be harmful to human eyes. Never look
directly into the optical port of any fiber optic unit designed to operate
with single-mode optical fiber.
NOT FOR LIFE SUPPORT SYSTEMS
Liteway, Inc. does not authorize or warrant any of its products or
accessories for use in critical life support systems or applications of any
kind.

MIDI-2201-x Receiver
The MIDI-2101/2201 system consists of
the MIDI-2101 transmitter and MIDI-2201
receiver. This system will transmit all
standard MIDI 1.0 data signals over
beyond the specified 50 foot (15 meter)
limit without signal loss or interference
between the two MIDI units.

Bit-error Rate 1 x 10-9 (worse case)
Signal Connectors 5 pin 180° DIN
Input Isolation Optical Isolation 10 KV/us
Output Drive 25mA maximum (5 times MIDI 1.0)
Operating Wavelength 850 (-1), 1300 (-3,-7), 1550 (-9)
Optical Output -15 dBm typical
Optical Loss Budget 0 – 10 dB
Optical Connectors Multimode fiber models (-1, -3) ST/PC,
Single-mode fiber models (-7,-9) FC/PC
Temperature Range -35º to +75ºC
Power Requirements 11-24 VAC/DC @160 mA
Physical Size (mm) 5.0”(127)L x 1.0” (25.4)W x 3.0”(7)D

Installation Instructions
The diagrams below show the location of the connectors for the MIDI2101 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
Note that you must
connect the Tx port
of one unit to the Rx
port of the other unit
with the appropriate
size fiber optic cable
