ABL-1A01-R, Single Port Active Video Balun
Active UTP Video Balun Receiver
Active Visions active video balun receiver conditions balanced signal and converts it into an amplified unbalanced signal with no video distortion, which can be applied in applications such as video monitoring and video meeting. It can transmit four channels of video simultaneously on a single CAT-5 twisted pair wire. It can simplify wiring and lower expenses.
Connect the white striped wire of a pair from the CAT-5 unshielded twisted pair cable to the + terminal of the green socket and connect the solid color wire to the - terminal. Connect the BNC interface of the video balun receiver to your monitor or recording equipment. If there is a splice in the circuit, please use a splice block or termination strip to ensure perfect contact at the splice.
Type of required wire:
Only use standard unshielded CAT-5 or better twisted pair wire. The wire quality will directly affect the transmitted image and transmission distance.
Characteristic impedance: 100Ω20Ω
DC loop resistance: 18Ω/100m
Differential capacitance: 62pf/m (Maximum)
Adjust the BRIGHTNESS knob to adjust the image brightness, then adjust the SHARPNESS switches to adjust the image sharpness and color. Adjust the switches according to the transmission distance. Use the diagram below for your reference.
Frequently Asked Questions
Why does my video look like a scrambled TV signal?
This typically indicates reversed polarity.
Can shielded twisted pair be used?
Shielded wire can be used up to a few hundred feet. However we do not recommend it. Its high-frequency roll-off will severely degrade the transmission distance and performance.
Can Category 6 wire be used?
Yes. Unshielded Twisted Pair wire, Category 5 or better, can be used with UTP video transceivers.
Can I transmit more than one video signal in a multi-pair wire bundle?
Yes. One of the benefits of using Active Vision video transceivers is the interference rejection. UTP video signals can reside in the same wire bundle as multiple video signals, ringing telephones, Ethernet, low voltage power, RS-422, RS-485, etc.
