Troubleshooting
If the communication module does not respond, here is a list of general troubleshooting tips:
1. Check the wiring connection. Ensure the wiring is correctly connected and the connector is not loose.
2. Check the power to the CoreSense module. Check the power supply line and ensure the power is on and
the green LED is on.
3. Check the module network address. The address should match the address that the master has requested.
The valid addresses are 1 to 31. “0” is not a valid address.
4. Check your master data format setting. Ensure the master node data format setting to: RTU mode, 1 start
bit, 8 data bits, no parity bit, and 2 stop bits.
5. Check the master node baud rate setting. Set your master node baud rate as 19200 and then try to
communicate with the module. If the module does not respond, then set to 9600 baud rate and try it again.
Any third party PC debugging tool can also be used by sending a query for getting the firmware version number.
The response indicates the version number as 1.01R00 (this number is only an example and may change
according to models).
