Emerge EMS 2000 series Installer/User Guide

To Connect Cascaded Transmitters

1.  Attach a suitable video cable between the socket labelled 

RGBHV OUT

 

on the primary transmitter and the socket labelled 

RGBHV IN

 

on the secondary transmitter. (Cable specification: Fully 
shielded with 15 way male D-type connectors at 
both ends, 6 feet or less).

2.  Attach a stereo audio cable between the socket 

labelled 

 on the primary transmitter 

and the socket labelled 

 on the secondary 

transmitter. (Cable specification: Shielded 
with three way 3.5mm jack plugs at both 
ends).
