11. FAQ and Solutions
11.1 RS232 Communication - Device Not Responding
Solution:
Device and host communication uses RS232 straight-through cable:
- RX to RX
- TX to TX
- GND to GND
11.2 Analog Input Reading Zero or Very Low
Troubleshooting:
- Check sensor wiring connections
- Verify sensor power supply
- Check if channel is configured for correct input type (4-20mA vs 0-10V)
- Test sensor output with multimeter
- Verify sensor is functioning properly
- Check for broken wires or poor connections
11.3 Analog Input Reading Maximum or Very High
Troubleshooting:
- Check for short circuits in wiring

- Check for loose connections
- Add filtering in software if necessary
- Check sensor power supply stability
- Verify proper cable termination
11.5 Multiple Devices on RS485 Bus
Important Notes:
- Each device address must be unique
