The basic VBS/VBL-250 configuration
consists of the video transmitter, Vidi-Wire
Antenna, and DTC cable part number

4045170-024. 

This cable is connected to the

multi I/O port of the transmitter, and is
configured to supply:

•

The video signal from the camera to the
transmitter.

•

Power to the transmitter through the
internal battery pack.

NOTE: You will need external camera

power if voltage to the transmitter is not

compatible with your camera’s operating

voltage, and/or you need greater battery
life, and/or your camera draws more than

200mA.
