The Black Box ServSwitch Matrix Video Switch (4 x 4) allows you to electronically switch the video signals from as many as four source devices among as many as four destination devices. All of its inputs and outputs are buffered, so you always get the sharpest possible images. To top it off, it can drive those signals as far as 150' (45.7m). You can control the ServSwitch using the included standard serial numeric keypad - which is powered by the Switch. You can also control it by attaching a PC or other serial device that can send the Switch the ASCII characters or hex codes equivalent to the keypad key presses.

In the ServSwitch application, almost any video device can be involved, including TVs, VCRs, cameras, projectors, DVD players, etc. This is because the ServSwitch can handle almost any kind of video synchronization. It supports RGBHV, which is used in VGA, SVGA, and other types of computer video. It also supports RGBS, which is used in NTSC and PAL TV signals. It can support RGsB (sync on green) as well. It's also worth mentioning that the ServSwitch has an impressive amount of bandwidth that can carry video 1600 x 1280 resolution video at refresh rates up to 85 Hz.
