K
Adding a user
To add a user to the device, you use the command K. For example the command
K1,+3581234567890
adds
a user named K1 or if there is already a user on the same name, the command changes the phone number
for that user. Only the phone number for users K1 to K9 can be added or changed. You can add or change
only one user per one SMS command. The user is added to the SIM card of the device.
5.2.2
R
Resetting the motion detection information
The command resets the motion detection information and re-enables the use of “GPS STOP” for the
device (the device will send the “GPS STOP” message if the device has not moved for a certain amount of
time). The device can send the ”GPS STOP” message only once and after that it has to be reset with the R-
command.
5.2.3
SMS
Locating with SMS
The commands set the device to use SMS locating instead of data. Using SMS based locating consumes less
power and can work in poor reception where normal data tracking does not work. Note that the command
is in capital letters.
Note!
When using the Ultracom Global SIM Powered by Telia SIM card, changing the locating method (SMS
or data) can be limited.
5.2.4
GPRS
Locating with data (GPRS)
The command sets the device to use data to send the location. Note that the command is in capital letters.
5.2.5
GPRS+
Locating with data (GPRS) and SMS
The command sets the device to use both data and SMS to send the location. If the device is unable to send
the location with data, it will try to send the location with SMS. This is the default setting for the the device.
Note that the command is in capital letters.
5.2.6
APN
Setting the access point name (APN)
With the APN command you can define a carrier APN to the device, if it is not an APN that the device
automatically has stored in its memory. After the APN command is a comma or space and then the APN of
the carrier. The APN must be re-sent to the device if the SIM card of the device is changed. The command
must be written in capital letters, for example
APN,
internet
where internet is the example APN of a carrier.
Note!
When using the Ultracom Global SIM Powered by Telia -card, the APN must not be sent to the device
using the APN command. The device will automatically recognize the card and change the APN to the
correct one.

Replies to commands
5.3.1
P, T, M, V, G and R
The device replies with an SMS to P-, T-, M-, V-, G- and R commands. The device replies with a message,
from which the user can see the current settings and other information, for example
(5) P,4,6!,12,16
GMT+2 V632 T21 G23 L3,0 -PGPS3 U3.0 snro:1431234
.
To an unknown or incorrect command, the device
will reply with a similar message, but in front of the message is an error text.
•
(5)
Fifth reply message. All of the reply messages have numbers so that the user knows what
message is the latest and which settings are currently in use. Sometimes the replies to commands
don’t come in the arrival order, so the current settings that are in use can be seen by looking which
message is the latest (has the highest reply message number). The reply message number is reset
when the device is restarted.
