needed to connect the two devices.

Please review the literature for the specific interface for more details.

8 Troubleshooting

If LoggerNet/PC400W software is unable to establish a connection with the

modem:

1. Check your account information (you may have to call your provider for

this or look at your agreement).

a. Verify there is coverage at your location.

b. Check the Network light. Network – indicates a successful

connection to the cellular network with an IP Address given and a

channel acquired.

c. Make sure the modem has sufficient power.

d. Check the signal strength using AceManager (make sure your antenna

is properly connected and oriented). Signal strength should be in the -

51 to -90 range (-51 is a strong signal, -90 is a weak signal).

e. If you have a Static IP account, verify the Static IP Address.

Preceding zeros in the IP address are not entered in LoggerNet.

f. If you have a Dynamic IP account, you will need to have a DDNS

(dynamic domain name server) name that LoggerNet can reference to

make the connection.

g. Connect with the modem through the serial port using AceManager.

If the modem has been configured for “PPP” (see Appendix A), then

you may have to check the “Use SOS Mode” box.

h. From the “Status” group, make sure the “Network State” is “Network

Ready”, and note the “Network IP” address. This is the current IP address for

the modem (a dynamic IP address will change each time the modem is reset).

Try connecting to this IP address using LoggerNet. If LoggerNet connects with

the IP address, but not with the modem name.domain name, then there may be

a problem with the Dynamic IP setup in the modem.
