SETUP SCREENS
Tracker IIIC does. If you have a Tracker IIIC and select INTERNAL, an error message will be
displayed because an internal GPS receiver will not be found.
Data output on Tracker IIIC is limited to echoing the data input. This provides a useful
RS232 buffer for connecting other listening devices to your GPS data output.
Skymap IIIC can output standard aviation RS232 data at 9600 baud or NMEA 0183 format
RMC, GGA and RMB sentences at 4800 baud. See APPENDIX F for full details.
The AVIONICS INTERFACE output setting for Skymap IIIC is for use when connected to
the Bendix/King Avionics Interface Module (AIM). The AIM is an optional accessory
allowing you to connect your Skymap IIIC to other aircraft instruments including the
Autopilot. Key 4 will only appear if the AVIONICS INTERFACE output is selected and
calls Screen 37, the output test page (Skymap IIIC only).
The second box is for information only, and is only shown when the GPS Source is
External. The unit will automatically sense the type of incoming data. It first sets up the
default data type and then if the incoming data is not recognised, it steps through the other
data input options until it finds a format it recognises.
The data type the unit is looking for will be displayed next to the DATA INPUT heading.
Once a valid format is found, searching will be disabled. Valid data input types are NMEA,
AR-NAV (RS 232) and Northstar binary data at either 1200, 4800 or 9600 baud. See the
section on Data Input for further details.
Once a valid format is recognised and sentences are being decoded, the word YES will be
displayed next to RECEIVING DATA. If the data is not recognised or is not present, the
word NO will be displayed. If the position information in the data being received is valid
and useable, the word YES will appear next to the words DATA VALID, if not then the
word NO will be displayed.
When Skymap IIIC is used with an external GPS source, the data output will be limited to
OFF and ECHO INPUT.
