GSM modem on: Yes

SIM card found: Yes

PIN set: Yes

PIN accepted: Yes

Sleepmode OK: Yes

PUK required: No

Default IMEI nr: No

GPRS: Yes

GPRS IP conn.: No

Attempts left to enter PIN: 3, PUK: 10

The above shows that:

• The GSM modem is on.

• A valid SIM card is inserted.

• The SIM card was activated with a valid PIN code.

• The GPRS feature is enabled.

• The GPRS connection is not established.

The GPRS-related lines from the above-displayed output of the GSMSTAT

command are shown only by RTU firmware versions capable of the GPRS

communication mode (for version information see below).

Other information is also listed, but it is of no concern to the user, except the PUK

required entry. If this parameter is Yes, it can be the result of entering a wrong PIN

three times in a row. You can see this also in the last string displayed by the

GSMSTAT / GPRSSTAT command (number of retries left).

To reactivate the card you will need its PUK number, which you also get from your

cellular provider with the SIM card. To reactivate the card, enter the command

GSMPUK pppppppp nnnn (where pppppppp is the PUK code and nnnn is the

new PIN). Note that the new PIN is used immediately to activate the SIM card.

The command GPRSSTAT is a synonym for GSMSTAT.

WARNING: Your A733GSM/GPRS RTU has an internationally unique identification number

(IMEI). This number is on a leaflet packaged with your device, and you will need it

if you lose the device. Please keep the number in a safe place.

2.3.1 GPRS usage of an A733GSM/GPRS RTU

Configuring the GPRS Parameters

To configure your A733GSM/GPRS RTU for usage with GPRS, ensure that the

module has firmware version 2.10 or above installed. If your A733GSM/GPRS RTU

features a Motorola GSM/GPRS module, be sure to have firmware version 2.14 or

higher installed.

Verify that you have configured the GSM Parameters as described in the previous

section (GSMPIN, GSMROAM).

Note: If you want to use only the GSM features of the RTU, you have to set “GPRSPORT

0“ to disable the GPRS capabilities. The power consumption will then be as low as

with the older GSM-only units.
