VBA-Programming example K8090 8-Channel Relay Card

Is a programming example available in VBA (Visual Basic for Applications as is used in MS Access or Excel) for the K8090 8-Channel Relay Card (VM8090)



Quite by chance I saw this message. In 2016 I have written an Excel VBA program to control the card. I can send you a demo excel file with the code.
I have written some remarks on the checksum on this forum.

If you are interested in the demo, please mail me at frans.westendorp@kpnmail.nl
