Abstract

A communications interconnect between the countermeasure controller of a countermeasure system and the dispenser containing the countermeasure payloads therein. Additionally, the present disclosure provides a power connection between the countermeasure controller and the countermeasure dispenser to deliver power to the countermeasure payloads, including smart payloads, utilizing existing vehicle wiring harnesses and wiring kits.

First claim

The invention claimed is:

1 . An enhanced fire select multiplexing (EFSM) assembly for a countermeasure dispenser system comprising:
at least one sequencer; a 28V power control module; a first magazine identification line operable to connect the at least one sequencer and the 28V power control module to a first transceiver and a first 28V bus; a second magazine identification line operable to connect the at least one sequencer and the 28V power control module to a second transceiver and a second 28V bus; a first countermeasure expendable payload connected to the first transceiver and first 28V bus; and a second countermeasure expendable payload connected to the second transceiver and second 28V bus; wherein the EFSM assembly is configured to provide power and data transmission to at least one countermeasure expendable payload from one of the first and second countermeasure expendable payloads over a single fire pin pair; and wherein the first and second transceivers and 28V busses are operable to deliver 20 W of power to the first and second countermeasure expendable payloads.

2 . The EFSM assembly of claim 1 further comprising:
a circuit card assembly having the first magazine identification line and the second magazine identification line thereon; and
a countermeasure controller containing the at least one sequencer and the 28V power control module therein.

3 . The EFSM assembly of claim 2 wherein the first transceiver and first 28V bus are operable to deliver both power and data to the first countermeasure expendable payload.

4 . The EFSM assembly of claim 3 wherein the second transceiver and second 28V bus are operable to deliver both power and data to the second countermeasure expendable payload.

5 . The EFSM assembly of claim 1 wherein the first and second transceivers and 28V busses are operable to deliver data at a 500k baud rate to the first and second countermeasure expendable payloads.

6 . The EFSM assembly of claim 1 wherein the countermeasure dispensing system further comprises:
a vehicle carrying a countermeasure dispenser containing the at least one expendable payload therein.

7 . The EFSM assembly of claim 6 wherein the at least one expendable payload further comprises:
at least one of flares, chaff, and steerable decoys.

8 . The EFSM assembly of claim 6 wherein the vehicle further comprises:
an aircraft having an A-kit wiring harness therein.

9 . The EFSM assembly of claim 8 further comprising:
a wiring harness operable to connect the at least one sequencer and the 28V power control module to the A-kit wiring harness of the aircraft.
