3.1 Introduction

The Video and Stereo Audio Fiber Optic Transmission System is normally preset
for immediate use with audio input circuitry set for balanced 600-ohm input
impedance and output set for balanced audio. If a different protocol is desired,
it can be easily selected using the DIP switches located on the back panel
of the unit. (See Table 3-1.) There are indicator LEDs on the units for monitoring
purposes and various user-selectable options for the various signal types. The
following instructions describe the typical installation procedure and the function
of the LED indicators.
1. The various options, as already mentioned, have been preset. If unbalanced
high-input impedance or unbalanced output is desired, refer to instructions in
Tables 3-1 and 3-2.
2. Connect the fiber optic cable or cables between the transmitter and receiver
units. See Section 2.3 for a list of cables provided and Section 2.2 for the types
of signals they support.
3. Apply power to both transmitter and receiver units.
4. When power is applied, the green POWER LED will light, indicating the
presence of operating power. The green VIDEO LED(s) and AUDIO LED(s)
will light as described in Table 4-1.
5. Connect the audio input cables to the proper positions on the removable
terminal blocks. Be certain to check all connections and ensure that inputs
and outputs are not intermixed. Refer to Table 3-3, which describes the various
connections.
6. The system should now be operational.

3.2 System Switch Settings

The audio interface circuit used in this product has external switches that are used
