The 20-550-001 Balanced Line driver provides protection against ground loops and RF
interference for long cable runs. The 20-550-001 driver works in conjunction with the 20-550-002
receiver or the 20-550-003 Driver/Receiver. The driver converts a standard unbalanced baseband video
signal to a balanced video signal that is transmitted over two coax cables. The 12VAC wall transformer
provides isolated power to the Brick to control ground loops
