The 20-550-003 Balanced Line driver/receiver provides protection against ground loops and
RF interference for long cable runs. The 20-550-003 driver/receiver works in conjunction with another
20-550-003 driver/receiver, a 20-550-001 driver, or a 20-550-002 receiver. The 20-550-003 converts
unbalanced baseband video to/from balanced video. Two coax cables are used for the balanced video.
The 12VAC wall transformer provides isolated power to the Brick to control ground loops.
