Connector for signal output to PC plotter/NMEA equipment (J8) 
To PC plotter or NMEA equipment 
(1) NC  : Unused 
(2) RSRXD  : RXD signal input (reserved) 
(3) RSTXD  : NMEA signal output 
(4) NC  : Unused 
(5) GND  : Signal GND 
(6) NC  : Unused 
(7) RSRTS  : RTS signal output (reserved) 
(8) RSCTS  : CTS signal input 
 
 
 
(2) RSRXD and (7) RSRTS are used for special purposes. 
NMEA signals are output from (3) RSTXD and RS232C output is set at short circuit between 1 
and 2 of power terminal block jumper TB1, and RS422 (NEMA0183) is set at short circuit 
between 2 and 3.  To connect J8 and a PC plotter (RS232C port), use a commercial cross type 
DSUB9-pin cable (for RS232C). 
To connect J8 to different NMEA equipment, also obtain a commercial DSUB9-pin connector. 
In this case, make sure that the jumper of power terminal block TB1 is set between 2 and 3 
(RS422 level).
