Automatic TCP/UPD connection

(This does not apply to the Eco model)

The Auto TCP/UDP connection feature is defined for accessing serial devices over the Internet. Maestro 100 can be configured that after power up it will connect to a remote TCP/UDP socket (client mode) or to wait for the TCP/UDP socket connection request from remote peer (server mode).

If the socket connection is unsuccessful or disconnected it will repeat the connection request and back to waiting stage. This make remote peer can access serial device connected to Maestro 100.

Remote AT Commands by SMS

This feature is to control the modem to interpret AT command from incoming SMS, executing it, and return the result to sender by SMS.

The user can enable the modem to receive AT command by incoming SMS.

I/O Triggered AT Command

This feature makes use of the Maestro 100 Input/Output port as a sensor. If the signal to the port match the pre-defined condition a stored AT command will be executed.

Call Screening

This feature enables the Maestro 100 to reject incoming call if the phone number does not match one of the entries of authorized phone number list. Unauthorized incoming call will be hanged up within one ring.

Up to 10 authorized phone numbers can be stored. Each number can be as long as characters. Waiting call can also be rejected.

Modem status check and monitoring

The Modem Status Check and Monitoring feature makes the modem can check the status of the modem in either "one shot" or periodic (per minute) mode. Modem will also report check result by SMS if result is beyond preset limit, and reset automatically if losing network connection.

Following items will be checked:

network registration (periodic mode only, triggering reset)
rom test
signal strength (can trigger reporting)
IP address of modem (only when GPRS connection activated)
module battery voltage (can trigger reporting)
