By SMS command
By GPIO status change
Enter/exit the offline mode on call
For this option to work, enable switching to network mode on call or switching to the offline mode on call. Al-
so, an authorized phone No. group must be assigned to each of the options.
If you have both the switch to offline mode on call and network access on call configured, the device will
change its status
– if the device has been in the offline mode, it switches to the network access, and vice versa,
if internet connection has been established, it switches to the offline mode.
Exiting the offline mode by SMS
SMS command format:
XXXX wait on
– to switch to the offline mode (disconnect from network)
XXXX wait off
– to exit the offline mode (connect to network)
Where XXXX
– password for SMS message (four digits or Latin letters, case-sensitive). Default password –
5492. There must be a space after the password in the message.
Switch to the offline mode by a code word
When detecting a set of characters in data stream with the sequence corresponding to the sequence speci-
fied in the settings, the modem terminates connection and switches to the offline mode.
The code word can be a sequence of any symbols from 1 to 32 and from 0x00 to 0xFF. When entering the
code word, it is recommended to use non-printable characters in addition to ASCII-symbols, since in this case
the coincidence probability of the code word with payload is reduced.
It is not recommended to specify the commands used by the 3-G module and the commands used in the
communications protocol between the ATM modem and the iRZ Collector software as well as sequences that
are parts of these commands.
The following commands are not to be used as a code word:
NO CARRIER
CONNECT
SISW (^SISW; SISW:)
SISR (^SISR; SISR:)
RING
ERROR
OK
\xB5\xBC\xBD\xBE\xBF (\x indicates hexadecimal notation)
