Tracker3 User’s Manual 36
CUSTSYM on|off
Enables the use of custom symbols if they have been uploaded to a
compatible Garmin GPS receiver (using the Garmin xImage utility).
CWBEACON <text> (local only)
Sends <text> as a Morse code beacon.
DAO on|off
Enables transmission of the !DAO! extended-precision construct. This
provides an extra digit of precision over the standard APRS position
format, but results in a longer packet and may not be supported by all
APRS clients.
DEVLIST (local only)
Lists addresses of all connected 1-wire devices.
Return value: Number of devices detected
DIGI on|off
When enabled, the tracker will digipeat packets having its own callsign
( MYCALL ) in the next digipeater address field.
DIGIID <n> on|off
Enables callsign substitution for digipeater alias <n> (1 to 8). This should
normally be enabled.
DISPLAY (local only)
Lists all configuration parameters.
DOUBLE <n> on|off
When enabled, two identical copies of the position packet are sent with
each transmission. This should only be used with short packets when
extra redundancy is required.
DUMP (local only)
Displays the tracker’s memory contents for troubleshooting purposes. By
default only RAM contents are displayed. DUMP CONFIG displays
configuration memory contents, and DUMP ALL displays everything.
DUPETIME <0-255> (seconds)
Sets digipeating duplicate suppression period.
