Hello,
I’m using 2 x K8056 relay card to control an other hardware through RS232.
One of the cards is not working anymore, I tried with the the diagnostic tool to see if it’s working but for one of the card the communication can’t be done.
Can you please help me with this problem.
Thank you!
Try putting the PIC from the working card into the card that does not work, to determine if the PIC is the problem.
If the PIC is the problem, check if it has not accidentally been set to address 0.
If so, change the address.
If not, PIC is defective (unlikely but possible), in that case, return PIC for examination/exchange.
If the problem is not related to the PIC, please check assembly. You have a working item to compare voltages.
Hello, I already tried this(excange the PIC and I have the same setting for both cards ) seems that the PIC is the problem.
So, where I have to send the PIC?
I was thinking to buy another PIC but then I need the programming code, can I get this?
Thank you for your response!
Are you sure the PIC is not set to address 0?
This is a very common problem and many people think the IC is defective.
Does the manual mode work? If it does, then most likely the PIC is not defective
Sorry, for copyright reasons we do not supply source code or hex files.
You can return the PIC for inspection/exchange to:
Velleman Projects Tech. Dept.
Legen Heirweg 33

Hello,
not even the manual way is working.
I will send the PIC for inspection.
Thanks,
Meli
