Hall Research 210-LU

The Model 210-LU buffers and splits component (RGBHV, RGBS, or RGsB) video signals for display on two monitors. The unit can drive video cables up to 150 feet or longer depending on the resolution used and cable quality.

The input video signal can be RGBHV (five connections, separate syncs), or RGBS (four connections, composite sync), or RGsB (sometimes referred to RGB - three connections, with sync-on-green).
The device is capable of outputting separate, composite, or sync-on-green based on a switch setting independently for each output. For example you can set output # 1 for separate sync and output 2 for sync-on-green regardless of the type of sync at the input. The Model 210-LU can be powered from a supplied power adapter, or from customer supplied +5V DC.
