ioLogik W5300
Utility: ioAdmin
3-33
Cellular Reconnection
Carriers disconnect idle mobile device connections in order to save bandwidth for other on-line users and
applications. To keep the ioLogik W5300
Always On
, the ioLogik W5340 must not only have the capability to
detect the cellular connection and reconnect to the network once it is disconnected, but also needs to send out
signals (ICMP package) to notify carriers that the ioLogik W5340 is still alive.
NOTE
The default setting of the Cellular Reconnection function is
disabled
, which prevents it from producing extra
packets. If the Cellular Operation Mode is set to
On-Demand
, we recommended
NOT
activating the Cellular
Reconnection function.
Carrier Check before system restart:
Carrier Check settings define the timeout for detecting the physical
cellular connection. Once the ioLogik reaches the timeout, it will perform a system restart.
•
GSM Timeout:
When you turn on the ioLogik W5300, the device will continue to connect to the GSM for a
period of 60 seconds (the default setting). If it fails to connect, the device will automatically restart the
modem board after sixty seconds.
•
GPRS Retry:
After the connection between the device and GSM (carrier) has been made. The device will try
to connect with the Internet. After XX time of failed retry, the W5300 will restart the modem board.
The Chart below shows the Carrier Check behavior:
PING Check before system restart:
A remote destination is used in this setting to indicate if the Internet
connection is still alive. The user can specify a public IP or URL and the number of retries that are allowed.
•
Dest IP/URL:
Can either be an AOPC server IP or any public URL for the device to check its connection with
the internet.
•
Auto Retry:
Will be activated when the AOPC can’t connect with the AOPC server. The W5300 will tell the
machine to ping the Dest IP/URL to check for an Internet connection.
