Additional Information For Registering and Going Offline
Module Activation and Registration
When you buy the module from iDEN operators your module must be registered in
the system database. Upon power up, the module is registered and a set of data
parameters is downloaded over the air into the unit. In case the module is not
registered, you will need to give to the system administrator the unit IMEI number for
registration (some operators may also need the serial number of the unit). These
numbers can be found on the unit label together with the model number, the FCC ID
number and the Canadian safety ID number.
AT-commands:
Each AT command sent is expecting its own response as an echo, or an OK.
To make the iO1500R module re-register perform these steps:
1. Send the AT+WPDEREG command to un-register the module.
2. Wait three second for the iO1500R module response.
3. Send the AT+WPREG command to register the module.
4. Wait 5 seconds. Do not check module response while waiting.
5. Poll registration status using the AT+WPREGSTATE command.
6. Wait for 2 seconds for the reply from the iO1500R.
7. Loop: If the DTE did not receive a response go back to Step 5.
8. If the “ REGISTERED” response is received, proceed to the next stage.
Monitoring The RS232 CD pin and Going Offline:
While online, the DTE should monitor the CD signal on the iO1500R to see if it went
inactive. If the iO1500R did go inactive, DTE should do the following:
1) Tear down the PPP/SLIP connection.
2) Disconnect the module using +++ string, wait one second.
3) Send an AT command. The module should respond with an OK. If the DTE is
not getting an OK it should continue sending +++ to disconnect the module.
4) Wait one second and send the AT command until an “OK” is received.
If the timeout elapsed with no module response or during wait time another massage
has been received (e.g. NO CARRIER) start to reconfigure the module all over again.
