For installation and operation of the IS15 instruments refer to 
separate manuals. There are two options for interfacing the IS15 
SimNet (see page 69) and NMEA0183. The SimNet interface is 
recommended and you need an AT15 Active Tee as an interface 
item (page 74). 
NMEA In 
This connection will provide speed, depth and temperature 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 Autopilot Computer Main Board, 
Terminal RX1+ and RX1–. See Figure 3-26. 
NMEA Out 
This will provide the instrument system with heading data. 
The connection is made by a Roblink cable from Autopilot 
Computer Main Board, terminal TX1+ and TX1– to the 
instrument NMEA socket (4). See Figure 3-26. 
You will need a minimum of two instrument heads to make the 
system both ‘listen’ and ‘talk’ (I/O).
