Sutron Corporation 8310 & 7310 Users Manual 8800-1125Rev. 2.7 (BETA) 4/16/2014 pg. 111
will offer different connection ports, based on the function they perform:
Message Port – used to receive self-timed and alarm transmissions from the
8310 in ASCII data
Command Port – used for SSP/CL command processing, so that the user can
change the setup, and view data in the 8310 directly through something like
Tempest.
Redirector Port – used for third-party SSP/CL communications redirected to
8310, so the user can change the setup, and view data. An example would be if
the user could not log onto Tempest directly, he or she can use something like a
HyperTerminal session to communicate to the Tempest to contact the 8310 unit.
ServerPassword
If not blank the GPRS Modem will use the password when accessing the server. This is used for
authentication purposes.
CSDShoulderTap
When enabled, CSDShoulderTap allows the user to call the modem using the phone number
given to the GPRS sim card. The modem then will connect to what’s set to “Command Port” as
long the modem can connect to the “PrimaryIP” or “SecondaryIP”. This gives the user another
way of making the GPRS modem connect to a master station such as Tempest.
The reason we have this settings is because if the user did not have a static ip address of the
GPRS modem but had the phone number of the GPRS, he or she can call the number, or send a
text with the command “STAP”. By calling the number, or sending the text, and the 8310 is
powering the GPRS using PwrOnTime, PwrOnInterval, and PwrOnDuration the GPRS will create a
SSP/CL connection to the master station even if the GPRS’s PwrOnAction = Listen. If sending a
text the user will receive a text message saying “Created SSP/CL session to PrimaryIP(user set)”
SMSTxmode
SMSTxMode allows the user to receive self-timed transmissions using SMS communication. An
example of this is when wanting to receive self-timed transmissions through your phone.
When SMSTxMode is set to “Scheduled”, and SMSTxList has a phone number in it the user will
receive text messages with self-timed transmissions every time a self-timed transmission is
supposed to occur based on TxInterval, and TxTime in GPRS settings. If the self-timed
transmission does not get through to the master station, the SMS self-timed transmission will
not occur either.
When SMSTxMode is set to “Fallback”, and SMSTxList has a phone number in it the user will
receive text messages with self-timed transmissions every time a self-timed transmission
doesn’t get through to the master station using the GPRS link.
Also the format of the SMS self-timed transmission will be based on the TxFormat set in GPRS
settings. Expect if the format is “SSP” due to it being in binary
CAUTION: SMS transmissions whether scheduled or fallback are limited to 160 bytes of data.
Users will have to limit their data sent per transmission or else the SMS message may not be
able to contain it all.
SMSTxList
Allows to user to choose what phone numbers get the self-timed, and alarm transmissions
based on what SMSTxMode, and/or SMSAlarmEnable is set too.
