For this connection, attach NMEA "A" and "B" signal wires to connector terminals 1 and 2 respec-
tively. These terminals are interconnected to the appropriate terminals in the previous slot within
the Bulkhead Box. No additional jumpers are necessary.

Pigtail Connection (3 JCUs in use)

For a Voyager II confi guration with 3 JCUs and a NMEA interface, all four JCU slots are occupied.
The NMEA card will reside in the JCU slot J4. Route the NMEA interface cable up to the JCU slot
J4 and, using a cable tie, anchor the NMEA cable to the 3rd JCU cable. Cutoff the shrink wrap
insulator on the end of the wires and using in-line crimp splices and attach the NMEA talker signals
A and B to the pigtail red and yellow wires respectively.
