DN24F08 FAQ

Hello,
I purchased the following board from you:

DN24F08 300MA Darlington tube output 8AI-8DI-8DO Multifunction IO Expanding Module for ARDUINO NANO V3.0 RS485 Modbus RTU Open PLC LED Current Voltage Sensor

I would like to operate the following display with it:

DM56A04 4 Bit DC 5V 12V 24V RS485 Digital Tube Characters LED Display Module Modbus RTU for PLC Configuration Software Configuration Software

Can you send me a code example for sending numbers via RS485?

Thank you very much.

This requires debugging.
1. Use the USB to RS485 converter to debug the DM56A04.
2. Use the USB to RS485 converter to debug the DN24F08, allowing it to issue commands that can control the DM56A04.
3. Then, let the DN24F08 control the DM56A04.
