(Not used in Dial-in mode)
:
These are for the GPRS or NextG network that the
SIM card connects to
– they are related to the APN server, not the FTP server. Many network providers
allow these to be blank. For correct settings, contact your network provider.
The
Command strings
are used to control the modem during each stage of the Sentek PLUS system
upload process. Sentek provides configuration files on the Sentek website to restore the network strings for
modems sold by Sentek. Generally, the settings should not be altered from the default settings provided by
Sentek in these files.
Dial-in Enable:
In Dial-in mode, after every Sample Count interval has been reached the telemetry power
is turned on and this string (up to 80 characters) is sent to the modem. The telemetry remains powered for
the time specified in Dial-in Uptime, and then the Dial-in Disable string is sent.
In normal (not Dial-in) mode, this string (up to 80 characters) is sent upon completion of an upload unless
the Dial-in Uptime is set to zero
– in this case, the dial-in feature is inactive.
This field can be used to command the modem to auto-answer incoming calls, for the uptime period, after
the sample count scheduled time.
Dial-in Disable:
In Dial-in mode, after a Dial-in Enable is sent, and when the end of the Dial-in Uptime has
been reached, this string (up to 80 characters) is sent, and then the power is removed from the telemetry.
This field can be used to prevent the modem auto-answering incoming messages at times other than the
sample count scheduled time.
In normal (not Dial-in) mode, this string (up to 80 characters) is sent before starting an upload. The Dial-in
Enable is sent at the completion of the upload. The telemetry remains powered for the time specified in
Dial-in Uptime, and then the Dial-in Disable string is sent.
If the Dial-in Uptime is zero the dial-in feature is inactive.
Init String:
This string (up to 80 characters) configures the modem for communication, after it has been
powered on.
Connect:
(Not used in Dial-in mode) This string (up to 80 characters) supplied by your Network provider, is
the command needed to connect to the network. It generally initiates the dialing of a specific telephone
number.
Disconnect:
(Not used in Dial-in mode) This string, up to 80 characters, is sent to the modem after the
probe has sent the data to the network. It will disconnect the modem from the network.
Response(s):
After being sent a command the modem replies with a response. If the specified response
string is not received within the timeout period (\
T…) set in the corresponding Network field, the will probe
abandon communication until the next scheduled time. This includes responses that do not match the
response string. The Dial-in Enable and Disable timeout is not dependent on the Connection Timeout
value. A reply is considered matching when the start of the reply exactly matches the response string (up to
40 characters).
