When in NMEA Mode the Mega can receive and display
instrument and navigational data input via the NMEA IN ter-
minals. This data will also be re-transmitted through the
NMEA OUT terminals.
NOTE If there is more than one Mega instrument installed on the
boat, the units should be interconnected as shown in Fig 4.15 -

4.4 Electronic Interference Suppression
IS12 has been designed to minimise the effects of interference
generated by the engine alternator. However, precautions
should still be taken by routing the cables away from the
engine compartment. Do not run the cables down trunking
carrying high current cables. The transducer cable should also
be kept separate from the boat’s radio antenna cable.
Engines with spark ignition, also some refrigerators should be
fitted with suppressors. Your local agent should be able to
advise on this and supply suppression kits where necessary.
