5.14 Performance Processor NMEA Input and
Output Configuration
The Performance Processor has two NMEA inputs and two
NMEA outputs. However if the RS232 interface is required
then only one NMEA input and output can be used. The
inputs are optically isolated, as required by the standard, so
there is no direct electrical connection between the talker
device and the Hercules System. The input requirement is
half the minimum drive capacity of a standard NMEA
output.
The two outputs are identical and are capable of driving at
least two NMEA inputs each (four in total). If data is
available then NMEA information is output once a second.
5.14.1 Changing NMEA/RS232 Configuration
Changing the NMEA/RS232 configuration is carried out by
adjusting the calibration on Cross Track Error as follows:
1. Select Cross Track Error on the display. If a page
has not already been set up to display cross track
error, then it can be found by cycling through the
options in the WAYPOINT Menu.
2. Using the Scroll Up and Scroll Down Keys scroll
to "CALBRATE" on the other half of the display.
Press Enter twice to show the current
configuration number (NMEA MDE).
3. Press Enter, the configuration number flashes.
4. Use the Scroll Up and Scroll Down Keys to
change the number as follows:
Mode Input 1 Output 1 Input 2 Output 2
0 183 183 RS232 RS232
1 183 183 - 183
4 - 183 183 183
The default setting is 0 for RS232 capability.
