n
Disconnect after inactivity period
Inactivity time: n seconds :
Enables or disables the idle timeout for the Remote Manager connection between device and
server. The idle timeout is enabled by default. Specifying “ none ” disables the idle timeout.
Specifying a timeout value enables the idle timeout, which means the connection will be
dropped after the specified number of seconds. The minimum value is 300 and the maximum
43200. In contrast to TCP keep-alives, the timeout managed by the “ connidletimeout ” option
is at the Remote Manager application level. The “ connidletimeout ” option provides a way to
close the connection to the Remote Manager server if no Remote Manager protocol data is
sent or received within a specified time frame. That is, the connection is idle with no traffic in
or out for that amount of time. This capability is particularly useful for server-initiated
connections. When a user on the server side requests a connection be established to a device,
that user needs to explicitly terminate the connection when they are done with the device. This
timeout allows you to configure the device so that a “forgetful user” does not inadvertently
leave the connection in place, which could cost money on a cellular connection if Connectware
or TCP keepalives are enabled and transferred needlessly between device and server.
n
Enable protocol compression : Configures whether RCI command and response text is
compressed, when both are passed between the Digi device and the Remote Manager server.
This compression primarily affects the size of the data passed when settings or state
information are formatted as RCI and conveyed between device and server. Using compression
on this RCI text can reduce the size of passed data, and, for cellular products, reduce the cost
of reading and writing device settings. When you enable RCI compression, the RCI command
and response text is compressed using LIBZ compression when it is sent between device and
server. The protocol used to manage and pass data between devices and Remote Manager,
known as EDP, internally negotiates whether compression is applied. RCI compression is
enabled, or “on” by default to reduce byte count and cost of sending data. As an example of
savings, typical cellular router settings will compress to about 8% of its original size, which
means that you can send data in far fewer packets and less time, than an uncompressed
version of the same data. Only disable RCI compression for technical support and
troubleshooting purposes. For example, if you want to eliminate the possibility that this
compression is causing some sort of problem.
