Hello,
I try to drive a K8056 relay card under labview 8 via serial (rs232) connexion.
The test software given on your website is running well, but I didn’t manage to drive the card with labview. I’m using the VISA serial VIs. I think there is a problem of syntax for the instructions or maybe i’m wrong with the checksum.
I’m trying to toggle the first relay :
chr$(13)
1
T
1
255-(13+49+84+49)+1=61
Here are the bytes i send. I’m not sure for the separation and end caracters, so i tried \ and \n.
The problem is that if these bytes are right or wrong. There are too many possibilities.
Thanks for your help !!
