Troubleshooting Communication
►
To troubleshoot a communication problem:
1
Check that the modem or switch/router is functioning properly.
2
Check that the connection to the internal connector on the SMI communication board is properly
done.
3
Check that the selected communication option is properly configured.
4
Check whether a firewall or another type of network filter is blocking communication.
5
Verify that the Status field in the Server Communication Status window displays OK. It indicates that
the SMI has established a successful connection and communication with the specified server
port/device (LAN, RS485, internal ZigBee module or external GSM modem).
If the status is not OK, a text message is displayed:

For RS485 slave devices: No Master Found: The master device is not responding or the RS485
cable is not connected.

For GSM modem and ZigBee module errors, refer to their relevant manual.
►
To troubleshoot Ethernet communication:
When Ethernet communication is used, use the Server Communication Status , as described on page 25, to
identify the location of the error.
