3.1  About the WP-27 / WP-28 

The Kramer 

WP-27

 and the 

WP-28

 constitute a twisted pair transmitter and 

receiver system for component/composite

1

 or Y/C video, as well as stereo 

analog / S/PDIF audio signals. Each unit can power or be powered by the other 

unit over the same CAT5 cable. 
The 

WP-27

 transmitter converts the selected

2

 video and audio signals into a 

twisted pair signal and the 

WP-28

 receiver decodes that signal back to its initial 

stage. The 

WP-27

 accepts either a component video, composite video or s-

Video source. The selected video source, as well as the selected audio source

3

 is 

transmitted to the 

WP-28

, which outputs that source accordingly

4

 

If CV-Y/C is selected, the 

WP-27

 accepts a CV

5

 or Y/C

6

 signal

7

 and 

transmits it over the CAT5 cable to the CV or Y/C output on the 

WP-28

 

receiver 

 

If component video is selected

8

, the component video signal

7

 is transmitted 

over the CAT5 cable to the COMP output on the 

WP-28

 receiver 

 

If the ANALOG stereo audio source is selected via the AUDIO button, the 

WP-27

 converts it to a digital 48kHz 24 bit signal which is transmitted, 

together with the video signal, over the CAT5 cable to the 

WP-28

 receiver 

 

If S/PDIF (digital audio) is selected via the AUDIO button, it is transmitted 

together with the video signal over the CAT5 cable to the 

WP-28

 receiver 

                                                       

 

1 Either s-Video or composite video (both inputs cannot be connected simultaneously) 
2 Via two INPUT select buttons letting you choose the video signal input and the audio signal input 
3 The audio signal is outputted to both outputs simultaneously 
4 The WP-27 and WP-28 do not perform any video signal format conversion. A composite video source would need to be 
routed  to  a  composite  video  output  or  an  s-Video  source  would  need  to  be  routed  to  an  s-Video  output.  Similarly,  a 
component video source would need to be routed to a component video output 
5 By connecting only a CV input and releasing the Y/C-CV COMP VIDEO INPUT button 
6 By connecting only a Y/C input and releasing the Y/C-CV COMP VIDEO INPUT button 
7 And audio signal 
8 By pressing the Y/C-CV COMP VIDEO INPUT button
