Input and Output Connections
The input and output connections to the system are made to the jacks mounted on the rear
panels of the CU0TD/RD-1 thru CU0TD/RD-5 systems, the drivers for the CU1TD/RD-1 and
high power systems, to the Watt amplifier drawers and to the Axciter Drawer if present in
your system. The CU0TD/RD-1 thru CU0TD/RD-5 systems and the drivers for the
CU1TD/RD-1 and higher power systems accept an On Channel RF signal (RD) or a SMPTE-
310 (TD) input and output a digital RF ON Channel signal. Refer to Figures 3 & 3A and to
Tables 2 & 2A that follow for the locations and information on the jacks and connectors. If
your system contains the Optional Internal GPS Kit, the output of the GPS Antenna
connects to the J5 TNC connector on the rear panel of the CXB drawer.
