controllers menu or via parametrization software in “provider settings”.
Alarm system (Plug & Play)
When any event or alarm is received from the meter interface, the controller sends all the data received from
the meter and the controllers information (IMEI, IP) using http protocol to the url address specified in the
settings menu “Plug&Play server address”.
Time synchronization
The controller synchronizes time with GSM network provider or NTP server. The device’s time zone can be
set and changed in the Device configuration menu. The current time is used for audit and event logging.
Passive Client (dynamic IP address)
This option is used when the client has dynamic IP SIM card or the SIM card cannot be accessed from the
server, but the modem could connect to the server. It can work in report mode or in passive client mode.
Report mode sends information about existing IP address to the server (UDP). Enabled passive client mode
requires remote server address set in the settings. In this mode, the modem connects to the remote server
and holds the open connection. This way the system should identify the connected modem and would be
able to read data using live session. Note! In passive client mode the controller always has the connection
open to the server so more mobile data can be used for upload than average.
Reports
Reports regarding signal strength , IMEI, IP address, events can be sent as an UDP message to multiple IP
addresses or phone number via SMS depending on APN and their settings.
Report interval is a configurable value.
Report example: “SQ:-51dBm IMEI:355233050381548 IP:212.47.100.164 SN:170170170170
SMS control
Depending on APN a list of allowed numbers can be set to allow parameterization by SMS or to send
periodic SMS reports with device status, SIM ID, signal strength, IP address.
SMS Parameterization
SMS parameterization command syntax is as follows below. Important! Command keys must be sent in
lower case only. MAX sms size – 160 symbols.
SMS command syntax: <keyword>:<parameters or commands key=value;><parameters or commands
key=value;> !Important. No signs ( ; = ) must be used in parameters. For example:
smscfg:dev_userpassword=PA:SS;=WORD; is not allowed.
Example: “ smscfg:dev_rebootperiod=1000;smscmd:sendreport;smscfg:dev_userpassword=asd; ”
Alternative: “ smscfg:dev_rebootperiod=1000;dev_userpassword=cccc;smscmd:sendreport; ”
If successful, the command will request the device to change the default automatic reboot value to 10
minutes and send report to data center.
Depending on the outcome the device will respond to each command in the following way:
Ok;ok;ok;
OR
Error;ok;error;
If device will not recognize the command the response will be “No valid command”.
The entire command list is displayed in the Annex A. “Controller menu and configuration settings”.
