Before getting started
Typically the purpose of using the GPRS SLL is to provide internet services to an RTU
and hence the LAN is not available and not used, but during initial testing setup it’s very
convenient to take advantage of it. The problem is that if the internal LAN is turned on
then GPRS messages will be sent using the LAN and not the GPRS device. To avoid this
you should just go to the LAN Settings Setup entry and turn it off.

Configuring the serial ports for GPRS operation may require changes to the registry that
will require a reboot before they take effect. When this situation can be detected, you will
be notified of the need to reboot. However, it cannot always be detected. If you
experience any difficulties establishing a connection when setting up a port for the first
time, try rebooting the Xpert.
