PREFACE
The video twisted-pair transmitter TTR 202 is a
double correction amplifier with the standard
asymmetrical video inputs and symmetrical
outputs to connect the twisted-pair cables. It is
suitable to fit in a 19” standard rack 3U. Pre-
emphasis selection enables better video
transmission through the long distances.
FEATURES
19”/3U rack mountable
small dimensions 3U/6TE
simple connecting
low power consumption
over-voltage protection
pre-emphasis +10 dB / 5 MHz
CONTROLS AND CONNECTORS
(1) / (9) POWER
Green LEDs as power-on indicators.
(2) / (8) J1, J21
