TTU-2900 Hardware & Installation Guide - PULS Wiki
This configuration process is accomplished via a series of SMS Commands:
1.
Power up the TTU-2900
™
and your handset
2.
From the handset, send an SMS message to the TTU-2900
™
phone number:
Where ddd.ddd.ddd.ddd is the publicly addressable IPV4 address of your LM Direct
™
server and ppppp is the UDP port number
3.
Alternatively if a URL has been set up for your LM Direct
™
server, the LMU may be programmed with:
Where myURL.MyCompany.com is the URL assigned to the server
4.
Verify your settings by sending the commands:

Activating LTE Using AT Commands
There are two variants of LTE modems; LTE AT&T and LTE Verizon. Both variants require a SIM card to be inserted.
If you get an LMU without a SIM card (which is the typical case), the operator will simply ask for the IMEI of the LMU. The IMEI (International
Mobile Equipment Identifier) is printed on the label of the LMU. Again, DO NOT give the operator the CalAmp ESN of the LMU.
The operator will provide you with a SIM card for each account activated. If they are especially nice (or you are especially persistent) they will
also give you a list tying the IMSI (International Subscriber Identifier) of the SIM to the phone number assigned to it. Please note that the operator
will likely tie the IMSI (i.e. the SIM) to a specific IMEI. Making sure the specific SIM matches to the right IMEI isn’t strictly necessary, but it
will keep everyone’s book-keeping a little cleaner. You may also obtain this information by running a CSV report in PULS (after the devices have
connected to the network and sent in their first ID Report). See the PULS Users Guide for more information.
If you do happen to have a SIM card, the operator will ask for the IMSI and ICC-ID (Integrated Circuit Card Identifier) along with the IMEI of the
LMU. Again, in return you should get a list of IMSIs and Phone Numbers.
The IMEI, IMSI and ICC-ID are all available through the
ATI1
command. The IMEI should also be printed on the label of the LMU.
Operators can offer more than one type of APN and can even set up a custom APN just for your devices. The rates they charge will vary
depending on the APN service you want. Operators may also request you use a blank APN. With the APN, you may also receive a username and
password combination.
The last item an operator may provide is a SIM PIN. The PIN is effectively a password to the device. The main difference here is that the PIN will
restrict all the capabilities of the device, where the SPC is used just for configuration.
The activation sequence for an
LTE AT&T
modem would therefore look as follows:
To clear the APN, the following command can be used:
Only enter this next command if you have been given a non-zero PIN as any errors may lock you out of the modem.
