Part Number: TPT452
Title: Twisted Pair Repeater Tap
Category: A/V Baseband
The TPT452 Twited Pair Tap Repeater is a dual channel amplifier used to equalize video over twisted pair wire gages 18 to 24 AWG. The unit has one twisted wire video input per channel, Two BNC Tap or “drops” to use for a local monitor and two twisted pair video outputs per channel ( a distribution amplifier) so that the unit can drive two separate video lines with the same camera picture. This unit is used in the middle of a long twisted pair wire installation to extend the transmission range of the video signal up to 4000 feet.
This unit is compatible with all other twisted pair sender and receiver units. The distance is set using field progragmmable jumpers and front panel adjustable equalization controls for both high and low frequency.
Each video input has a screw terminal connector for the twisted pair wire. The video drop has a female BNC connector that takes the place of a video balun. Two screw terminal connectors are used for the dual twisted pair video distribution output.
The video input uses a true common-mode rejection system that eliminates interfering signals and ground-loop problems. Controls for both video level and picture definition can be adjusted to conrrect for twited pair wire loss making the video output (BNC Drop) correct.
The TPT452 “Pre-Equalizes” the twitsted pair transmission path to reduce video noise and improve the video image. Because it is an active device it will correct the twisted pair wire impedance of the incomming video signal and produce the precise impedance to correctly match the twisted pair wire. A correct match on the twisted pair wire will prevent reflections and ghosting in the video picture.
