The A-PNL-AUX96-3 option provides convenient
access to all signals on the motherboard auxiliary
control connector. This is accomplished with two circuit
boards: the Terminal Block board and the Connector
board. The Terminal Block board mounts to the subrack
rear panel and has six 16 pin headers that mate with 16
position plug-in screw connectors. The plug-in screw
connectors use a clamping action to secure stranded or
solid conductor wires from 22 AWG to 16 AWG and have
locking screws to ensure the connector does not loosen
due to vibration. A label on the back of the subrack
rear panel lists the signals at their respective positions.
The Connector board is soldered to the Terminal Block
board and provides the interconnection between the
auxiliary control connector on the motherboard and the
Terminal Block board.
A close-up view of the auxiliary connector
label shows the short signal name for
each connection point. Defi nitions for
these signals can be found in the SR-
39-1 subrack manual. Extra General
Purpose Input / Output connectors
(GPIO) that can be used for diff erent
functions depending on the control card
are listed to the right of the connectors.
For example, the AC-3E audio control
card uses these lines for auxiliary audio
inputs / outputs and auxiliary COR /
PTT connections. The CI-PM-3 paging
modulator uses these signal lines for
connecting A/D select lines, 2-level and
4-level data, etc. The custom functions
of these connectors will be marked in the
blank space next to the signal name.
See Table 1 and Table 2 for a list of
connector names by control card and by
transmitter and receiver series.
