D. Wiring between the AIM or NAIM and the Optional 24-bit DIP Switch Module
Connect the 24 logical inputs and two grounds from the optional switch panel to the 31-pin
connector (that mates to the connector on the AIM or NAIM) in the proper pin configuration. Table
103 contains a description of the AIM connector pin-outs. Table 104 contains a description of the
NAIM connector pin-outs.
NOTE: The optional 24-bit DIP switch module consists of a series of 24 mechanical switches,
each of which provides a logical 0 input to the AIM or NAIM with the switch open circuit
and a logical 1 input to the AIM or NAIM with a contact closure to ground using the ground
provided by the AIM or NAIM. The resistance of a contact closure to ground must be less
than 10
Ω
and the resistance of an open circuit (switch open) must be at least 100 k
Ω
. The
24-bit DIP switch module is used to input the COSPAS-SARSAT 24-bit data for the
Aircraft Address Number protocol and requires no power source to operate.
