You Need The TX-MVX!
The TX-MVX is part of the group of versatile TX series products from Radio Design Labs. TX series
features the advanced circuitry and high quality connectors for which RDL products are known. The ultracompact TX series can be mounted in limited space using the adhesive methods popularized by RDL’s
STICK-ON
brackets available from RDL. Rack-mounting is possible using the TX-RA5 Rack Mount Kit.
APPLICATION: The TX-MVX is the ideal choice in installations where either a manual switch or an opencollector must switch video signals. Video A is normally connected to Common. When the TRIG terminal
is pulled to ground, Video B is connected to Common and Video A is disconnected. The TX-MVX utilizes
a high quality RF relay allowing the module to either switch a single video source to one of two
destinations, or switch two video sources to a single video destination. The actual switch (or other module
actuating the switch action) may be located remotely from the TX-MVX.
Many RDL modules feature an open-collector TRIG control terminal. These terminals may be used to
control the TX-MVX. Alternatively, relay contacts on other equipment may also be used to control the
TX-MVX. For example when used with other RDL modules, the TX-MVX could switch video:
• Using audio detection (ST-ACR) from an external audio source
• Using video detection (TX-VCR) from another video source
• At a prescribed time during a power-up sequence (RU-SQ6)
• From logic signals (ST-LCR)
• Using wall-mounted remote controls (RT2 or RC2-ST)
Use the TX-MVX individually in NTSC or PAL systems, or combine it with other RDL RACK-UP

series. The TX-MVX may be mounted directly to a backboard using optional mounting

, TX, or FLAT-PAK™ series products as part of a complete audio/video system.
