AMX VSS2 Installation Manual

Overview
The VSS2 Video Sync Sensor (FG5916-10) is equipped with two independent signal
detection channels. When a signal is present, each detection channel initiates a logic-level
output, and dual video jacks for each channel allow loop-through operation. The VSS2 is an
ideal power sensor for DVDs and other video sources, or to provide a warning on loss of
audio, video or RGB signal.
FIG. 1 VSS2
Common Application
Use the VSS2 to monitor the true power status of a VCR, tuner or satellite receiver and track
the video output of each source, sending a logic signal to an input port.
The output can also be used to control other AMX closure-driven peripherals, such as the
PC1 Power Controller.
Features
• Detects presence of signal from 1 kHz to greater than 100 kHz
• 2 independent video sync sensing channels
• 2 RCA jacks for each channel to allow loop-through operation
• 2 solid-state outputs that send a logic low signal when sync is present
• Front-panel LEDs that display on/off status for each channel
• Compatible with all AMX solid-state and closure input ports
• Detection of audio, video, and high-resolution RGB signals

Installation
You can install the VSS2 on any flat surface that has unobstructed access to the rear panel
connectors. The following describes how to set up and install the VSS2.
Connecting the Wiring
You can connect up to two video devices to the RCA plug-in connectors on the VSS2. Once
attached, you can connect up to two external sensing devices, a television manager, or a
AMX control system to the four-pin Sense out connector on the rear panel.
The following sections describe how to connect your video devices, external equipment, and
the 12 VDC power supply
