USER MANUAL

Single Channel Active Video Balun Transmitter

Model: VAB100T

The VAB100T video transmitter is an active device that allows the transmission of real-time monochrome (B/W) or color video via Unshielded Twisted Pair
(UTP) cable. Baseband (composite) signals of any type are supported. The unit receives one channel of video from camera using coaxial cable and sends
out one channel of UTP signal with screw terminals as the connection. The VAB100T is compatible with active or passive receivers (e.g. VAB100R or
VAB400R) with transmission distance of up to 1200 m / 4000 ft. Each switch can be independently adjusted for the different transmission distances and
image quality based upon the type and quality of the cable being used. With interference rejection, the VAB100T allow video signals to co-exist in the same
wire bundle as telephone, datacom, or low voltage power circuits. This allows the use of a shared or existing cable infrastructure.

Features:

• Transmit a full motion color video signal up to 1200 m / 4000 ft and a
B/W video signal up to 2400 m / 8000 ft.

• Supports all bandbase signals including PAL, NTSC, SECAM.

• Signal Transmission via UTP cable.

• Transmission Signal 1Vp-p Composite Video.

• Built-in transient protection and ground lifting, which eliminates

damaging voltage spike problems.

• Built-in Filter: 0~6MHz

• Can work with 4-channel Hub or 1U rack mounting receiver panel.

• BNC Video Input

• Red LED: Power on/off

• Yellow LED: Signal

• Power supplied 12V DC

Switch Chart: Each switch can be independently adjusted for the different

transmission distances and image quality based upon the type and quality of
the cable being used.

Troubleshooting:

All transmission distances mentioned above are without connecting image processors (e.g. Quad, Multiplexer, or DVR). The transmission range would
be reduced 100~200m / 300~600 ft upon different camera, cable, DVR … etc.
These products are designed for long range transmission, utilizing the built-in video amplifier function. If your transmission range is under
100 m / 300 ft, setting the video gain function too high will result in snowy, wavy, or overly bright images. It is recommended that this product be used for
long transmission distances over 100 m / 300 ft. For shorter distances use an alternate passive video transceiver such as the VB100 series.
Both of the active transmitter and receiver have "4 position distance range switch" for different range transmission. Please adjust to appropriate range
upon your application to avoid any weak or bad image.
