PwrOnInterval + PwrOnTime + PwrOnDuration
PwrOnTime, PwrOnInterval, and PwrOnDuration are used to specify when the modem is
powered PwrOnInterval specifies how often to power on, PwrOnTime specifies an offset to the
interval, and PwrOnDuration specifies how long to stay powered.
For example, with PwrOnInterval = “01:00:00”, PwrOnTime = “00:30:00”, and PwrOnDuration =
“00:15:00”, the modem will be powered on every hour at half-past the hour, and will stay
powered for 15 minutes.
By powering on the LAN the user is given the ability to communicate with the 8310 over the
TELNET, TCP/IP, HTTP protocols. As well as send self-timed, and/ or alarm transmissions (this
can be done without the power mode settings enabled too)
The reason we give the user the ability to choose these settings is because by leaving it to be
powered all the time, for instance, would not be a cost efficient way of handling the modem.
PrimaryIP and SecondaryIP
When the LAN device attempts to send a selftimed or alarm message to the master station, the
8310 shall try using “PrimaryIP” up to a certain number of times, and then try “SecondaryIP” up
to a certain number of times, with a few seconds pause between each attempt. The 8310 shall
repeat this cycle until a connection succeeds.
MessagePort
Message Port is the port number the mater station will be listening on for self-timed
and alarm transmissions from the 8310.
ServerPassword
If not blank the LAN device will use the password when accessing the server. This is used for
authentication purposes.
Use DHCP – When Yes, the 8310 uses the DHCP service provider on your LAN to obtain an IP
address at boot-time. Set this to No to specify a static IP (an IP that does not change with each
boot), as well as other advanced configuration data like Subnet Mask, Default Gateway, and DNS
and WINS servers.
Note: when DHCP is set to Yes, the other settings are not displayed.
Station Setup/Communications/COMx GPRS
This menu provides access to all GPRS settings needed to configure the GPRS modem for self-timed
and/or alarm transmissions via GPRS and/or SMS communication, as well as command processing. A
typical GPRS Settings menu is shown below followed by a description of all the fields.
