Interphase Proble - NMEA 0183 Interface

43
NMEA 0183 Interface
The Probe will accept navigation data from some Loran C,
Decca, and GPS receivers in the NMEA 0183 data format.
This interface has been tested and is verified to work with the
Interphase Pilot GPS. It features a unique, fully dedicated
microprocessor for the NMEA 0183 data port which provides
maximum compatibility among Loran C, Decca and GPS
receivers.
If your equipment conforms to the following NMEA 0183
Version 2.0 non-differential interface protocols, the Probe is
probably compatible- BOD, GLL, IMA, WDR, BPI, BWR,
BWC, BER, BEC, GXP, GDP, GOP, GLP, GGA, RMA,
RMB, RMC. Consult your operation manuals or contact the
manufacturer for further information on interfacing.
The Probe needs to be interfaced via the three pin jack on the
rear panel of the display unit. The pin connections are shown
at right. If using a GPS, make sure it is set to send NMEA
0183.
Interphase offers a 5-foot long interconnection cable and a
10-foot interconnect extension cable.
For reference, the internal circuity for the Probe’s NMEA
input is shown below. This technical information may be
helpful if you have difficulty with the NMEA connections.
