Configuring the CTM-200
If the IP address displayed is 0.0.0.0 or the online state is “NO” then the CTM-200 was unable to negotiate a
wireless connection. Check that the APN was entered correctly and the account is active.
The CTM-200 is designed to operate as an “always on, always connected” device. After successful configuration
the CTM-200 will attempt to maintain a network connection at all times. If the connection is lost due to out of
coverage or other reasons, the CTM-200 has internal logic to attempt to quickly reconnect to the network.
During loss of cellular connectivity report data destined for Fleet tracking servers is stored in non-volatile
memory. This data will be automatically forwarded when network connectivity is re-established.
Note: If the cellular device is incorrectly configured the CTM-200 will automatically power cycle approximately
every 4 minutes until it is configured for the correctly installed module.
