5.15.1 RS232C Input and Output Configuration

The Hercules Performance Unit has two serial input output
channels, one is used just for NMEA and the other can be
configured for NMEA or RS232C.

5.15.2 Changing NMEA/RS232 Configuration

Adjusting two calibration values (CAL VALs) on the Cross
Track Error function changes the NMEA/RS232
configuration. The first of these determines if RS232C can
be used and the second determines the RS232C baud rate
and format.

To configure the Performance Unit for RS232C, NMEA
MDE must be set to 0 (default). NMEA MDE can be found
as follows:

WAYPOINT

CROSS TR, CALBRATE

CAL VAL1 (NMEA MDE)

Full details of the meaning of other values of NMEA MDE
are given in the NMEA interfacing Para 5.14.1

To adjust the RS232C baud rate and format select BAUD
RTE as follows:

WAYPOINT

CROSS TR, CALBRATE

CAL VAL2 (BAUD RTE)

The units digit is the Baud Rate as follows:

1 = 300 Baud
2 = 600 Baud
3 = 1200 Baud
4 = 2400 Baud
5 = 4800 Baud
6 = 9600 Baud
7 = 19200 Baud

The tenths digit controls the format for input as well as
output as given in Table 6. The default setting is 6.2 (9600
Baud, 7 data bits, RTS/CTS). All data has at least 1 stop bit.
