RDL TX-AVX Automatic Video Switcher - 2x1 BNC

The TX-AVX is the ideal choice in installations where automatic switchover to an alternate video source is needed when the primary signal is lost. The unique power supply input allows the TX-AVX to be powered from a wide variety of existing ac or dc power sources. Features: Automatic Switchover to a Secondary Video Source Loss of Video Detection Dry-Contact Relay Output Detection of NTSC or PAL Signals Operation from AC or DC Power The TX-AVX has two video inputs and a single output. The detection circuit bridges the INPUT line. When a valid NTSC or PAL video signal is detected, the INPUTjack is connected to the OUTPUT jack. The output is designed to connect to a 75 ohm terminated load. In the absence of video input at the INPUT jack, the AUX INPUT jack is connected to the OUTPUT jack. The switching is accomplished by means of a high-quality RF relay. If power to the TX-AVX is interrupted, then theAUX INPUT jack is connected to the OUTPUT jack. The INPUT jack is 75 ohm terminate
