I Have the Chip Max485 and don´t know how to connect it properly with the board and what do i need to change on windows registry. I´m using the ASTER board and Colibri IMX.6. When i try to make a connection between the software and the port, it shows ReadTimeout Error
I´m communicating with a weighing module, that i have already communicated with the desktop of windows 10. The error that i´m refering occurs when i send the command Readline()
and it shows serial port exception: reading timeout. But when i send : Writeline()
it works
I have already configurated the registry, but i´m not being able to communicate with the module. Is there anything else i need to configurate besides changing the registry and uses a TLL to 485 Converter?
Dear @rafagcf,
Could you please see our documentation : https://developer.toradex.com/knowledge-base/rs485, there is information about the changes required to enable RS485.
Also, please look our developer articles : https://developer.toradex.com/search?q=RS485, you would get samples for the RS485 program.
Let us know if you need any other support on this.

Could you please clarify what exactly you do to communicate with a module and what are the symptoms of “not being able to communicate with the module”?

Please send us the following information:
- Schematic diagram of your RS485 circuit (How is the MAX485 connected to the Aster board, and how is the MAX485 connected to the external connector)
- Documentation of the weiging module (The weighing module’s specifications of the RS485 connection)
- Wiring diagram between your RS485 circuit and the weighing module
