5 FAQ AND SUPPORT

If no communication is seen or bad data is displayed, please refer to the FAQs below which cover the
most common configuration problems.
Is the attached device sending data over RS232, RS422 or RS485?
Check which serial mode your sensor has been designed or configured for, RS422, RS232 or RS485.
The receiving comport on the SMC Display must match the sending data.
Check the wiring as per the Manufacturers guide to see which output is being used.
Data is being received but is either seen as bad data or wrong data.
Verify that there is a signal ground connected for RS232, if not the data would not be readable.
Are the cables connected correctly, Note: RS422 uses a cross over Tx+ to Rx+, Tx- to Rx- etc.
Check the wiring continuity through to the sensor.
