NOTES: 1) If your transmitter (TD) system contains an Optional ASI to S310 Converter,
connect the ASI output of the STL to the ASI in jack on the rear panel of the
converter. Connect the SMPTE-310 Output from the SMPTE 310 Out jack on the
rear panel of the converter module to the input jack J1 on the rear panel of the
CU0TD/RD-1 thru CU0TD/RD-5 drawer or the driver drawer for the CU1TD/RD-1
and higher power systems. 2) If your transmitter (TD) system contains an
Optional K-Tech receiver, connect the RF from the receive antenna or one output
of the splitter to the input jack J1 on the rear panel of the K-Tech receiver.
Connect the SMPTE-310 Output from the SMPTE 310 Out jack J2 on the rear
panel of the K-Tech receiver to the input jack J5 on the rear panel of the
CU0TD/RD-1 thru CU0TD/RD-5 or the driver for the CU1TD/RD-1 and higher
power systems. 3) If the system contains the optional K-Tech back up system,
the K-Tech receiver is bypassed by using the second output of the splitter that
connects to J1 on the rear panel of the CU0TD/RD-1 thru CU0TD/RD-5 or the
driver drawer and connecting a jumper from J4 to J5, after removing the cable
from the K-Tech receiver, on the rear panel of the CU0TD/RD-1 thru CU0TD/RD-5
or the driver drawer. This configuration uses the 8VSB demodulator board in the
CU0TD/RD-1 thru CU0TD/RD-5 or the driver drawer to produce the SEMTE-310
signal. 4) If the system contains an optional preamp it connects to the output of
the receive antenna and to J1 on the rear panel of the CU0TD/RD-1 thru
CU0TD/RD-5 drawer.
J11 Power Monitoring Connections
In systems with one or more external amplifiers, J11 is used to communicate the output
forward and reflected metering voltages back to the driver. J11 is connected directly to
the external amplifier when there is only one external amplifier and is connected through
the system metering module when multiple external amplifiers are used. In multiple
external amplifier systems there are thermal switches mounted on the reject loads of the
combiner, and the Reject load interlock is connected to the thermal switches and is used
to shut down the system if the reject load overheats. In systems with no external
amplifier, the only connection used is the Reject Load Interlock, which must be connected
to Supply Return using a jumper from J11-6 to J11-9.
