Mitsubishi Electronics MAM-GM24 Activating/deactivating Modem Mode, Sending commands to the MAM

Operating modes: Modem Mode and TiXML Mode Configuration and projects

7.5.5Activating/deactivating Modem Mode

In Modem Mode, a MAM operates like a normal modem and establishes connections with the conventional AT command: “ATDT 0123456789”.

The MAM must, however, be switched beforehand from TiXML Mode to Modem Mode.

Activating Modem Mode

The following TiXML command can be used to switch the device to Modem Mode via COM1:

AT+TMode="ModemMode"

The device will send back the following acknowledgment:

OK

Once this command has been sent, the MAM will only recognize AT commands and will respond to these, for example, with OK.

Deactivating Modem Mode, activating TiXML Mode

If the device is in Modem Mode, it can be switched back to TiXML Mode using the following AT command:

AT+T Mode="TiXMLMode"

Response from MAM:

OK

Once this command has been sent, the MAM will only recognize TiXML commands and no AT commands.

E ATTENTION:

The MAM cannot send or receive messages if the red Modem Mode LED is lit. Alt- hough the MAM will continue processing the tasks, message jobs cannot be execu- ted until the modem is free again and the Modem Mode LED is off.

NOTE

AT commands are only processed by Mitsubishi Alarm Modems in Modem Mode. TiXML commands are only recognized in TiXML Mode.

7.5.6Sending commands to the MAM

Any terminal program, such as Windows Hyperterminal, can normally be used for entering and transferring TiXML and AT commands.

The following COM port settings are recommended:

115.200 Bit/s and 8N1 (8 data bits, no parity, 1 Stop bit, Hardware Handshake)
