5.7.3 Control via SMS Messages
The PSI-DATA/FAX-MODEM/RS232 can be controlled via SMS messages. For
example, you can activate the output, reset the alarm or send the status of the
modem simply by sending an SMS message.
This mode is activated using the AT\S2 command. In this mode, the SMS message
is not forwarded to the termination equipment, but is evaluated by the modem itself.
The SMS message sent to the modem must be structured as follows:
#<Password>:<Command>
The password (AT*P=) is the password stored in the modem (maximum of seven
characters). Please note that not all characters can be sent in the SMS message.
Choose a password according to the SMS character set. If the password is set,
e.g., to AT*P=12345 the message should appear as follows:
#12345:<Command>
The following control commands are available:
RESET Resets the alarm and the switching output
(e.g., AT*AR).
SET:OUTPUT Activates the switching output ("Output").
CLR:OUTPUT Deactivates the switching output ("Output").
SEND:STATUS Sends a status SMS message to the caller.
"Text" Outputs all the characters within the inverted commas
to the RS-232 interface.
Examples #12345:SET:OUTPUT Activates the output.
#12345:SEND:STATUS Sends an SMS message (status report) to the sender.
#12345:"RST PLC" Sends the text RST PLC to the terminal equipment
(RS-232 interface).
#12345:RESET Resets the alarm function and the switching output.
