Instruction Manual, Rev. 2 24
The AC distribution panel in a CU2TD has three circuit breakers that distribute the AC to
the individual drawers, which are the Exciter and the two power amplifier drawers. The
circuit breakers, which are accessed through the rear door of the cabinet, supply the AC
though AC line cords, that connect to the AC input jacks mounted on the rear panels of
the drawers. CB1 is a 30 Amp circuit breaker which supplies the AC to the (A2), top,
Power Amplifier A drawer. CB2 is a 30 Amp circuit breaker which supplies the AC to the
(A3), bottom, Power Amplifier B drawer. CB3 is a 10 Amp circuit breaker which supplies
the AC to the (A1) Exciter/Driver drawer. A maximum of four 30 Amp circuit breakers for
four amplifier drawers and two 10 Amp circuit breakers for two Exciter/Driver drawers can
be installed in the AC Distribution Panel.

CX Exciter/Driver Input and Output Connections
The CX drawer (CU0TD/RD-1 thru CU0TD/RD-5 system as well as the CU2TD/RD-1
system and higher) rear panel includes a number of input, output and serial connectors
that require the user to connect cables to when installing the drawer.
When configured as an RD system, the drawer accepts an On Channel RF signal. When
configured as a TD system, the drawer accepts an ASI or SMPTE 310M input. In each
case, the drawer outputs a digital On Channel RF signal.
When the system had been configured as a complete rack/cabinet mounted transmitter
system, cables have been installed in the rack/cabinet and hang loosely near the rear
panel of the CX drawer when it is pushed all the way into the cabinet. Each cable has
been labeled to simplify installation. Please refer to Figure 6 and Table 3 for the locations
and information on the CX drawer rear panel 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 CX drawer.
