4.24 IS15 Instrument

For installation and operation of the IS15 instruments refer to separate
manuals.
NMEA In
This connection will provide speed and depth input to the autopilot. If an
IS15 Wind Transducer is connected to the system, wind information will
also be transferred to the autopilot.
The connection is made by a Roblink cable from the instrument NMEA
socket (4) to the J3xx Junction Unit Main Board, Terminal RX1+ and RX1-.
See Figure 4-25.
NMEA Out
This will provide the instrument system with heading data.
The connection is made by a Roblink cable from J3xx Junction Unit Main
Board, terminal TX1+ and TX1– to the instrument NMEA socket (4). See
Figure 4-25.
You will need a minimum of two instrument heads to make the system both
'listen' and 'talk' (I/O).
If IS15 Expander is used in the instrument system, the NMEA connections
are made to this unit. See Figure 4-26.
