Hi,
Is there any information on the modbus registers for this HAT?
This link says it is still under construction
Thanks for any assistance
Hi,
I am attempting to use the card vis RS485 directly ( not using an RPI)
ID switches are set to zero
Terminator is on
485TX, 485RX are off
I have set up a modbus scanner using a USB to RS485 using this tool
Modbus Scanner: Perfect to Discover and Test Modbus - Chipkin
set to 9600,8,N,1
I can see the RS485 signals on the RS485 input to the board
Can you suggest anything else I need to configure?
Next step is to revert to using an RPI

Hi,
The default port settings for Modbus are 38400,8,N,1.
You either use the same on your scanner or change it using the command line interface (check the online help for details).
Ok great, 38400 did the trick!
Thanks
