Raven110 GPRS/EDGE AirLink Cellular Modem
7. Troubleshooting
If LoggerNet/PC400W software is unable to establish a connection with the
modem:
7.1 Check the Modem Configuration
Check the GPRS cellular account information, and verify there is GPRS
coverage at the site. Dynamic IP accounts require a Dynamic Domain Name
Server (DDNS) (Section 5).
If the cellular account is with CrossBridge Solutions, then CrossBridge’s
tunnel software must be running on the host computer for communications to
be established with the datalogger.
