Introduction

The AVS2 is a two input, one output, stereo video switch incorporating automatic programmable sync detection on either

video source.

NOTE: Source A will ALWAYS be routed to the output in the absence of power to the AVS2.

Modes

The AVS2 is designed to be set up in one of two primary modes:

MODE 1:

Input A is the primary source, input B is the backup source. In the presence of valid video on input A, source A will be
routed to the output. In the absence of valid video on input A, source B will be routed to the output channel.

The jumper configuration for this mode is as follows:
J4 - Out
JPR1 - A

(The location of the jumpers is shown in Figure 1A)

MODE 2: (Factory Default)

Input A is the backup source. input B is the primary source. In the presence of valid video on input B, source B will be
routed to the output. In the absence of valid video on input B, source A will be routed to the output.

The jumper configuration for this mode is as follows:

J4 - In
JPR1 - B
