The ETS PV891 is an RGB video balun with 4 BNC female connectors to an RJ45 jack.
The ETS PV890 Series of RGB Video Baluns enable sending RGB video signals over standard telecom wiring (UTP), of Category 3 or better quality. The PV890 supports RGB with SOG (sync on green), using 3 pairs of UTP. The PV891 enables RGB with separate sync to be run using 4 pairs.
Both baluns support monitors with resolutions up to 1024 x 768 pixels, at refresh rates of up to 75Hz. The RGB Baluns enable the user or installer to take advantage of pre-installed telecom wiring, or to gain the cost advantage of wiring with UTP instead of coax.
