4.18. Operating with Incoming SMS Messages
Incoming SMS commands are used for pins control in this modem version (see section
) to enter and exit the offline mode (see section
) as well as for single con-
nection to the server (see section
"Connecting to the Server via SMS Commands"
).
The SMS commands, received by the modem, are displayed in the log, and the password specified in the
SMS command is not displayed in the open form. If the password or command is invalid, the modem ignores
the SMS command received. If the password is invalid, the log prompts an error message
"Password Error"
.
4.19. Modem Operation in the Server Mode
The server mode can be relevant if a company rents an access point (APN) from the mobile network carrier
(or a public static IP address is rented for each modem). When APN is rented to all devices of the system (mo-
dems and a dispatcher center), private IP addresses are set. In this case, there is no need to rent public static
IP addresses for modems or operate with modems via the iRZ Collector server (see Fig. 4.6).
