I have a Piazetta P 963 pellet stove. We were having problems with an e12 error code and the stove shutting down. Contacted Piazetta and the tech in Santiago who came and resolved the problem. In the mean time I purchased a micronova bootloader so I could do some work myself. I received the bootloader but the only cable it came with was aTTL to TTL. I know from reading the forums that most stoves have the db9 serial port as mine does. My question is does anyone know where to get the cable for my stove.? Or would a USB to db9 serial work to upload firmware or adjust settings? Thanks
