For a suitable mating connector, use Tyco Electronics’ single-row Dualobe plug assembly
with flying leads (Tyco part number SSL015PC2DCXXXN, where XXX is length in
inches). This mating connector, with 12" leads, is available from KVH (KVH part
number 32-0780).
The next three sections explain the different interface options:
• Digital 100 Hz Asynchronous: see page 7
• Digital 1000 Hz Asynchronous: see page 12
• Digital 1000 Hz Synchronous: see page 18
• Analog: see page 24
