2.9.3 Receiver Interconnect — PCL6000/606/600 Composite
PCL6000, PCL606, and PCL600 receivers used in a main/standby configuration can be
interconnected to perform automatic switchover if detectable failure occurs in the on-line
receivers. As shown in Figure 2-11, the antenna is routed to each receiver through a power
divider such as the Moseley model PD-1000. The use of a power divider is recommended so that
the impedance as seen by each receiver is approximately 50 ohms.

Main/Standby Receiver Interconnect — PCL6000 Composite
The composite and mux outputs are paralleled using a BNC Tee connector. This is permissible
since the outputs are switched internal to the receiver. Only one of the receivers at a time will
have any output. The interlock control is achieved by first interconnecting the ground (GND) on
the two receivers. The XFR IN of each receiver is wired to XFR OUT of the other receiver. GND,
XFR IN, and XFR OUT are located on the barrier strip on the rear of the receivers.
