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.

Installation Instructions
The block diagram below shows the MIDI- 2001 in a typical
application.
Fiber Connections;
You must connect the Fiber Tx port of one unit to the Fiber Rx port of
the other unit with the appropriate size fiber optic cable. Multimode
models,( -1,-3) require 62.5/125u multimode fiber. Single mode
models (-7,-9) require 9/125u single mode fiber.
Fiber Optic Cable Connectio ns
Power Connections;
You must power each MIDI-2001. You can use the PS-1205 wall
transformer or any 12-24 Volt source.
Terminal Block Pins;
Pin Function
Alarm output for use with optional Alarm Sensing Unit
ALM-1000. No other connections should be made to this
1
terminal.
2 +11 to 24 DC or AC Volts input
3 AC or DC return (Common to Housing)
Indicator Lights
Indicator Lights when
Pwr Proper power is present.

MIDI Connections;
The MIDI IN connector on the MIDI-2001 unit should be connected to
the standard MIDI signal that is to be transmitted over the fiber optic
cable. (the MIDI out of your device)
The MIDI OUT connector on the MIDI-2001 unit should be connected
to the standard MIDI signal that is to be received over the fiber optic
cable. (the MIDI IN of your device)
A MIDI data signal is being transmitted on to the

Link
fiber optic cable. At low data rates this indicator
may blink with data.
A valid fiber optic connection exists between the
two MIDI units connected together. If the Link light
is not on MIDI data will not be transmitted
