(P/N MCBH5F-SS) and an OceanServer digital compass cable (P/N 19-00061-24)
which includes the DB9 connector and the battery pack. To fabricate the cable
harness, cut off the small connector on the compass cable and splice the cut wires
to the wires of the 5-pin bulkhead connector in accordance with Table C-1
.
