4Setting up a tracking unit
Use the MapExplorer to change the settings on the unit - including recording intervals, power saving
and GPRS parameters. Map Explorer can communicate with a tracking unit in three different ways –
serial cable (COM), GSM (modem), GPRS (TCP/IP). You can also change many settings without using
Map Explorer by sending SMS messages.
GPRS communication can be changed be SMS:
Setapn apn username password
Note that all commands are case sensitive and the first character must be in upper case.
If your operator does not use username and password verification then send the word
For example for Orange send and SMS to the phone number for the SIM in the tracker:
Set_apn orangeinternet null null
Verify your APN settings with your provider as they vary between operators and even different contract
- returns and SMS with the current location of the tracker in Lat/Long
returns information about the tracker including serial number, firmware version and
permanently disconnects the GPRS connection
one time GPRS connection that updates all the history on the server and then
disconnects - useful for minimising charges when in roaming mode
SMS commands are case sensitive.
If the tracking unit is currently communicating over GPRS it may take longer to receive an SMS reply.
