I'm not sure where this should be posted but I have a board which is accessed via a AT683 ModBus / J-Bus Communications Card
Connection to the main board is via RS232 ribbon cable connection and connection to ModBus / J-Bus is via RS485 using a 9-pin D-type connector
I am finding it very difficult to find someone who could develop some simple VB.Net functions which will read and write to the board.
Does anyone know of someone who could help. I am based in the UK but it can be anywhere
Thanks
