Hardware Reset Thresholds: You can configure these settings to clear any error states that
n
were resident in the Digi device's cellular module, so the device can once again connect to the
network, if the connection is lost. It does this by first resetting the cellular module after a
default or specified number of consecutive failed connection attempts, and then resetting the
Digi device after a default or specified number of failed consecutive connection attempts. You
can also disable each of these connection-failure settings.
Link Integrity Monitoring settings: You can configure these settings to perform a selected
n
test that examines the functional integrity of the network connection, and take action to
recover the connection in the event that it is lost.
Hardware reset thresholds
Hard reset the modem module after the following number of consecutive failed
n
connections: Enables or disables a hard reset of the cellular modem module after the specified
number of failed connection attempts. Specify a value between 1 and 255. The default is 3.

n
Enables or disables a power-cycle of the Digi device after the specified number of failed
connection attempts. Specify a value between 1 and 255. The default is 0, or off.
Link integrity monitoring settings
Enable Link Integrity Monitoring using the test method selected below: Enables or
n
disables the link integrity monitoring tests. If this setting is enabled, the other Link Integrity
Monitoring settings may be configured and verify the functional integrity of the mobile
connection. The default is off (disabled).
There are three tests available:
Ping Test
l
TCP Connection Test
l
DNS Lookup Test
l
You can use these tests to demonstrate that two-way communication is working over the
mobile connection. Several tests are provided because different mobile networks or firewalls
may allow or block Internet packets for various services. Select the appropriate test may be
selected according to mobile network constraints and your preferences.
The link integrity tests are performed only while the mobile connection is established. If the
mobile connection is disconnected, the link integrity tests are suspended until the connection
is established again.
For the link integrity tests to provide meaningful results, the remote or target hosts must be
accessible over the mobile connection and not through the LAN interface of the device (if it has
one). That is, the configure the settings to guarantee that the mobile connection is actually
tested.
The link integrity test settings may be modified at any time. The changes are used at the start
of the next test interval.
