6.6Getting to Know the TP-12N Video/Audio Twisted-Pair Line Receiver
The KRAMER TP-12NVideo/Audio Line Receiver works in conjunction with the TP-11NVideo/Audio Line Transmitter. The TP-12Nallows parallel connection of several units on the same line (one transmitter/multiple receivers), that can be tapped at any point without affecting image quality. When connecting several units, all the termination switches on the rear panel of the TP-12Nmachines, except for the last on the line, should be toggled to the Hi-Z position. The frequency response of the TP-12Nmatches that of the TP-11Ntransmitter, and it provides polarity switching on the rear panel.
NOTE
For Installation, operation, maintenance and troubleshooting instructions please refer to sections 8-13.
