Configuration
Before it can be used on-air, the Tracker needs to be connected to a PC, to set up its
configuration (once these are set, they are stored in non-volatile memory).
The PC connection is made via the serial “COM” port – a 9-way D-type. Some newer laptop PCs
don’t have these, so a “USB/RS-232” COM-port adapter will be required.
The connection to the PC must be by a “Null-modem” lead or adaptor, which has the following
connections:
There are a number of different parameters which need to be set.
In some cases, the terminology is slightly different between the two Trackers:
TinyTrak OpenTracker
Setting
Callsign
Usually add a -9 SSID suffix after your callsign
(this is a convention for mobile stations)
Digi Path Path
“RELAY,TRACE2-2” (this governs how your signals will be
digipeated by other stations)

Auto TX Delay TX Delay
the time between PTT enable and sending data (if your radio
has a slow-locking synthesizer, or transmit/receive relay, you
may need to increase this to ~ 500ms)
Auto Transmit
Rate
TX Interval
how often do you want your beacons to be transmitted? (Set a
fixed interval, or use SmartBeaconing, where the rate depends
on your speed)
Status Text Text
space for your own comment.
(keep this brief, or your packets will become too long)
It’s best to send the text separately after every few (3 or 5)
position beacons.
Send Altitude Altitude
if your GPS reports altitude, this can be included in your
position beacon (but it increases the length of the packet)
Only send Valid
(Don’t) require
GPS fix
prevents transmission of position packets if the GPS loses lock.
MIC-E Compressed
encodes the position in a compressed format, to reduce the
packet length
SmartBeaconing
allows you to change the rate of beacon transmissions
depending on your speed, and when turning corners

Note that both Configuration programs suggest a default path of “WIDE,WIDE”: this setting is used in
the USA, but not in Europe.
