COM300 Voice Communication Modem

8.2 For Problems Encountered When Making Data Calls
1) Verify you have selected the correct calling modem from PC208W's setup
screen.
2) Verify the COM port you are using is activated. As a power saving
feature, some notebook computers do not automatically activate the COM
ports.
3) Verify nothing else is using the same COM port on the computer. Even if
a program is minimized in Windows, it may have a lock on the COM port.
4) PC208W, Campbell Scientific's communication software, has a log level
I/O log that will display an activity of communication as the link is being
established. Assuming the above items are O.K., the software log should
display something such as “ATDT#######”. Where the #### is the
telephone number listed in the dialing path of the software for the
datalogger you are trying to call. As you are connected to each device in
the communications link, this will be reflected in the activity screen. This
may help to pinpoint which device in the communications link is failing.
To comply with FCC Rules and Regulations, all repairs on the COM300
modem must be performed by Campbell Scientific, Inc. or an authorized agent
