7.2.6 Auxiliary audio input
Note Only available on units fitted with the EHX80 expansion board.
The expansion board upgrade on the RS86/RS87 allows auxil-
iary audio input—e.g. from a radio receiver or an entertainment
system—to be fed into the intercom/loudspeaker system.
Note The auxiliary input must be a line-level signal (0.775V rms).
Connect the line out from the auxiliary source to the terminals
marked “AUX AF” as shown (Fig 7.11).
7.2.7 NMEA 0183 input
The inbuilt NMEA 0183 processor allows navigational position
information to be received from a GPS or chartplotter. The
boat’s position is automatically transmitted when a Distress
Alert is initiated.
NMEA input must be of the 0183 format, versions 2.0–3.0, out-
putting sentences GLL, RMC, and ZDA at a Baud rate of 4800.
The NMEA Out connections from the GPS/plotter should be
connected to the “NMEA In” terminals as shown (Fig 7.12).
