Buy a 1553 interface card?
That's a start...
MIL-STD-1553 is a balanced signal (has a + wire, a - wire and a
ground/shield) for each channel. One channel usually has DUAL REDUNDANCY,
meaning Channel 1A and channel 1B... if channel 1A fails (and the box is
programmed correctly), channel 1B will be used (why? because it isn't nice
flying home with half an airplane).
The signal strength comes in two "volumes": DIRECT COUPLED and TRANSFORMER
COUPLED. Direct is 3V to 9V p-p. Transformer is 9v - 27v p-p. When
reading these signals, clip an O-scope Channel A onto 1553 Channel 1A+ and
O-scope Channel B onto 1553 Channel 1A-. select ADD and INVERT on your
O-scope.
MIL-STD-1553 is a 20-bit stream.
Bits 0, 1, 2 are SYNC.
Bits 3, 4, 5, 6, 7 are Remote Terminal
Bit 8 is Transmit/Receive
Bits 9, 10, 11, 12, 13 are Subaddress
Bits 15,16,17, 18, 19 are Word Count/Mode Code
Bit 20 is Parity
The 1553 language is standard world-wide (yes, the same stuff from Bejing to
Hoboken). How you get it to talk, or fill data buffers, or address Remote
Terminals and Subaddresses with Mode Codes or Data is proprietary, so you
will have to surf the site of the manufacturer.
Have fun!
