The CatLinc VGA-L allows VGA connection between two devices using CAT5, CAT5e, or CAT6 twisted pair cable. Connection is made to devices using standard male HD-15 connectors. CatLinc VGL-L extends VGA signals up to 91 m/300 feet. At typical distances this product will provide excellent image quality for all resolutions. It can be used for longer runs, but the image quality may be reduced (see chart below). SP Controls recommends use of shielded CAT5 cable with the CatLinc system. A single screwdriver adjustment at the Receiver allows fine-tuning for best picture detail. The CatLinc VGA-L Transmitter provides a local loop-back female VGA cable to split the signal to a local display in addition to the CAT5 connection to the receiver.
