Once you click on that bar a serial communication activity windows appears
as shown below. By clicking on the icons below this window you can save
the contents of the window to a file or the clipboard so the information can
be captured for sending in with a support request.
When this window is opened on the home screen an additional entry window
appears below the activity window that lets you send commands directly to
the modem. This can be used to send diagnostic commands to the modem
and also to send non-standard configuration commands. Prior to using this
make sure the COM port and baud rate are selected correctly to match the
connection and setup of the modem.
7.4 Changing the modem and logger settings without Mobile
Data Assistant
The COM111 can be configured, as most such modems, using a terminal
emulator program by sending a series of “AT” commands to it. Please
contact Campbell Scientific for details of those commands if required.
The setup of the data logger can also be done using the Campbell Scientific
Device Configuration program. This can be used to manually enter the PPP
settings, change the communications port or its baud rate and also to control
the automatic call-back option. This tool may still need to be used if you are
running the logger’s TCP/IP stack and you wish to change the IP services it
supports as a server, e.g. http, ftp etc. These are accessed via Network
Services tab.
There are some other settings supported in the Modem which are not
changeable via the Mobile Data Assistant program. The modem supports the
dynamic DNS service for instance which can be used on some networks with
SIM cards that have dynamic IP addresses but which are public.
