About KD-4AUVRX
➔Receives real-time Color or Black & White video
➔KD-AUVTX Extends video up to 4,000 ft using a standard CAT cable when used
with an Active Transmitter (Key Digital Model KD-AUVTX).
➔KD-4AUVRX extends video up to 2,600 ft when used with a Passive Transmitter
Balun (Key Digital Models KD-PVB and KD-4PUV)
➔Manual Distance Adjustment switches for optimum picture quality at any length
run up to 4,000 ft.
➔Built-in interference rejection enables wire bundling with other low-voltage lines
➔Built-in surge protection, ground loop isolation, gain and loss control, and video
detection
➔Compatible with CAT5/CAT5e/CAT6/CAT7 cabling
➔Works with generic power supplies, from DC/AC 9V to 12 V (not included)
Installation and Operation
Before permanently securing the unit for final installation of
cabling behind walls or ceilings, test for proper operation of the
unit and the cables in your system.
Video Connections
➔KD-4AUVRX features two input options for video reception; a RJ45 port labeled
“UTP In” and a Phoenix Connector labeled “UTP In”. It is recommended that only
one of the two options be utilized as the CAT5/6/7 input.
»Phoenix Connector: Secure twisted pair wires into “Video
+” and “Video -” of Phoenix Connector block by loosening
screws, inserting twisted pairs, and tightening screws until
connection is secured. If using shielded CAT cabling, you
may insert shield into Pin 3 of Phoenix Connector.
»RJ45: Terminate the incoming CAT5/6/7 twisted pair wires
into your RJ45 connector in the following fashion:

Power Connections
➔Secure + and – power wires into “Power” inputs (Pin 1 and Pin 2) of Phoenix
Connector in the same fashion as securing Video connections. Positive (+) and
Negative (-) polarity can be inserted into any of the two “Power” inputs. Insert
Ground wire into Pin 3 if desired.
Uses with Active Transmitters
➔KD-4AUVRX units can be coupled with Key Digital’s KD-AUVTX Active Video

the KD-AUVTX Active Hub will provide quality video up to 4,000 ft.
Uses with Passive Transceivers & Passive Multi-Channel Transceivers
➔KD-AUVRX units can be coupled with a passive Transmitter/Transceiver (Key
Digital model KD-PVB) or a passive Multi-Channel Transmitter/Transceiver (Key
Digital model KD-4PUV) in your application. Coupling a Passive Transmitter/
Transceiver with the KD-AUVRX Active Receiver Balun will provide quality video
up to 2,600 ft.

Uses with Passive Multi-Channel Receivers
➔KD-4PUV units can be paired with additional KD-4PUV 4-Channel Passive Video
Receiver Hubs as part of a multi-camera CCTV system. Using the KD-4PUV with
the KD-4PUV Passive Hub will provide equivalent distances as when coupled with
other Key Digital Passive Transceiver Baluns; 1,300 feet.
Uses with Active Receivers & Active Multi-Channel Receivers
➔KD-4PUV units can be used as a Transmitter and coupled with an Active Receiver
(Key Digital model KD-AUVRX) or an Active Multi-Channel Receiver (Key Digital
model KD-4AUVRX). Coupling a KD-4PUV 4-Channel Passive Transmitter with
the KD-AUVRX Active Receiver Balun or KD-4AUVRX Active 4-Channel Receiver
will provide quality video up to 2,600 ft.
Note: The usage of a KD-4PUV balun to receive video signals from an Active Transmitter
(Key Digital model KD-AUVTX) is not recommended. For best results in an active/passive
coupling, it is recommended that the KD-4PUV Passive Video Balun be used as the
Transmitter, while the KD-AUVRX or KD-4AUVRX Active Video Receiver Baluns be used as
the Receiver.
