Reciter Auxiliary DC
Input
The system interface PCB in the reciter has an auxiliary DC input
connector. DC from the auxiliary DC output on the PMU (see “PMU
Auxiliary DC Output” below) can be supplied to the +AUX_V pin on the
system interface connector via this input.
The pin allocations for the auxiliary DC input on the system interface PCB
are given in the following table. Note that pins 1 & 3 and pins 2 & 4 on this
connector are linked. Refer to “System Connections” on page 60 for the
pin allocations for +AUX_V on each system interface PCB.
The DC output from the PMU is 12VDC. Although this power output is
isolated, the negative side of the supply is grounded on the system interface
PCB to give a +V output.
PMU Auxiliary DC
Output
The PMU can provide an auxiliary DC output when it is fitted with the
optional 40W auxiliary power supply PCB. This power supply is current
limited to 3A and is available on the auxiliary DC output connector on the
rear panel. DC from this output can be supplied to the +AUX_V pin on
the system interface connector on the reciter via the auxiliary DC input
connector on the system interface PCB (see “Reciter Auxiliary DC Input”
above).
The pin allocations for the auxiliary DC output on the PMU are given in
the following table. Note that pins 1 to 4 and pins 5 to 8 on this connector
are linked.
