Hi. I’m trying to work with this relay card trough the serial port.I have noticed that there is no microcontroller or RS232 connection in this card.However i’ve seen one kit (k8056) that works alon, and other interface card to connect trough USB to vm129, but recently i bought 3 of them.There is any kit with all pieces and electrical scheme that vm129 needs to work with RS232)
Thanks.
VM129 is a non-intelligent card.
Parts for modification are not sold separately.
If you require RS232 control, you can return the card and get a K8056 kit, this one contains all parts for RS232 control.
