PREFACE
The video twisted-pair receiver TR 404L is a fourchannel correction amplifier with four symmetrical
inputs and four standard asymmetrical video
outputs. Standard BNC type output connectors
enables the TR 404LP to be used with other
CCTV amplifiers, switchers, cameras, monitors
and digital video recorders All adjustments are
available with only three trimmers to adjust linear
and high frequency gain. There are green and red
LED which indicate the power-on and the video
signal error in the video input of the receiver.

INSTALLATION
The unit is suitable to use CAT 5 or other UTP (Unshielded Twisted Pair) cables, where is possible to
connect one or more units and enable to pass more than one video signal through the same cable.
(1)
Connect the power plug.
(2)
Connect the video monitor to the BNC video output connector.
(3)
Connect the twisted-pair cable to the video input terminal block connector.
(4)
Switch-on the unit.
POWER LED (green) lights, power supply is switched-on.
If there is a video signal at the input, ERROR LED (red) doesn’t light.
(5)
Switch-on the video monitor.
(6)
Set the correct output video signal (1 Vpp) - trimmer LIN.
(7)
Do the adjustment of high frequencies with trimmer HF1.
(8)
Do the fine adjustment of high frequencies with trimmer HF2.
(9)
Correct the output video signal (1 Vpp) - trimmer LIN.
(10) If there is too much noise in the signal, set the pre-emphasis to 10 dB in the video twisted-pair
transmitter and repeat the adjustments from step (6) to (9).
Maximum distances (CAT 5 UTP Cable) between different models of video twisted-pair transmitters and
receivers:
