PREFACE
The video twisted-pair receiver TRM 101C is a
correction amplifier with symmetrical input and
standard asymmetrical video output. Standard
cable with BNC type output connector enables the
TRM 101C to be used with other CCTV amplifiers,
switchers, cameras, monitors and digital video
recorders All adjustments are available with only
two jumpers to adjust the video signal gain on
whole frequency range.
FEATURES
very small dimensions
simple installation
AC/DC power supply
very low power consumption
over-voltage protection

(1) JUMPER J2
Jumper to adjust the video signal gain for
distances of the twisted-pair cable from 750m to
900m. When the jumper J2 is inserted the jumper
J1 has to be removed.
(2) JUMPER J1
Jumper to adjust the video signal gain for
distances of the twisted-pair cable from 450m to
750m. When the jumper J1 is inserted the jumper
J2 has to be removed.
(3) AC/DC POWER SUPPLY
Terminal block to connect the AC or DC power
supply from 12V to 24V.
(4) TWISTED-PAIR INPUT
Terminal block to connect the twisted-pair cable.
CONNECTIONS
Be sure to switch-off the power supply unit
before connecting to other equipment.
Also refer to the instruction manual of the
equipment to be connected.

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 video output BNC connector with cable to the video monitor.
(2) Connect the twisted-pair cable to the video input terminal block connector.
(3) Connect the power supply unit. (AC or DC)
(4) Remove the jumper J1, for the distances up to 450m.
(5) Switch-on the video monitor.
(6) Switch-on the power supply unit.
(7) Check the video signal on the video monitor.
(8) If there is too much noise in the signal, for the distances longer than 100m, set the pre-emphasis to
10 dB in the video twisted-pair transmitter.
(9) Check the video signal on the video monitor.
(10) If there is still too much noise in the signal, for the distances from 450m to 750m insert the jumper J1.
For the distances longer than 750m, remove the jumper J1 and insert the jumper J2.
Maximum distances (CAT 5 UTP Cable) between different models of video twisted-pair transmitters and
receivers:
