To wire an RS-232 device to provide input to an NMEA device:
1.
Connect the RS-232 Device’s
Tx
lead to the NMEA
Device’s
Rx+
lead.
2.
Connect the RS-232 Device’s
SGnd
lead to the NMEA
Device’s
Rx-
lead.
To wire an RS-232 device to receive input from an NMEA device:
1.
Connect the RS-232 Device’s
Rx
lead to the NMEA
Device’s
Tx+
lead.
2.
Connect the RS-232 Device’s
SGnd
lead to the NMEA
Device’s
Tx-
lead.
To wire an RS-232 device to provide input to
and
receive input from
an NMEA device:
1.
Connect the RS-232 Device’s
Tx
lead to the NMEA
Device’s
Rx+
lead.
2.
Connect the RS-232 Device’s
Rx
lead to the NMEA
Device’s
Tx+
lead.
3.
Connect the RS-232 Device’s
SGnd
lead to the NMEA
Device’s
Tx-
and
Rx-
leads.
There are some infrequent cases where binding the NMEA device’s
Tx-
and
Rx-
leads together may cause difficulties. If you do encounter
problems, you’ll need to use an RS-232-to-NMEA converter between
the two devices. A converter is typically required very rarely (in less
than 1% of applications; however, the modern Furuno radar systems,
for example, do require them), but is still a good place to begin trouble-
shooting if problems arise with the RS-232/NMEA interconnection.
