Reciter Auxiliary DC
Input from PMU
The system interface board in the reciter has an auxiliary DC input
connector. DC from the auxiliary DC output on the PMU can be supplied
to the +AUX_V pin on the system interface connector via this input (see
“PMU Auxiliary DC Output” on page 16
).
The pin allocations for the auxiliary DC input on the system interface board
are given in the following table. Older boards use the 4-way connector,
while the TaitNet RS-232 board and all other boards manufactured after
March 2005 use the 2-way connector. Note that pins 1 & 3 and pins 2 & 4
on the 4-way connector are linked. Refer to
“System Connections” on
page 20
for the pin allocations for +AUX_V on each system interface board.
The DC output from the PMU is 13.65VDC, 27.3VDC, or 54.6 VDC
(depending on the model). Although this power output is isolated, the
negative side of the supply is grounded on the system interface board to give
a +V output.

12V PA Power Saving Control Connection
To enable Power Saving in the 12 V PA, you must connect digital out 1 on
the reciter’s system interface connector to pin 1 of the Power Saving control
connector on the rear panel of the PA. Once this connection is made, the
PA will shut down whenever the reciter goes into Deep Sleep mode. For
more information on the operation and configuration of Power Saving, refer
to “Power Saving” in the Installation and Operation Manual.
Note
When a base station with a 12 V PA is configured for Deep Sleep,
digital out 1 is dedicated to Power Saving control and should not
be used for any other Task Manager function.
Two ways of making the Power Saving control connection between the 12V
PA and reciter are described below. The circled numbers in the following
instructions refer to
Figure 2.2 on page 19
