Chromeleon 6.8 not controlling GP50
I have a GP50 with 3.03 firmware. I put this pump in chromeleon config, but it doesn't respond to commands. I think that Chromeleon don't support my firmware version. In another same working system the GP50's firmware is 3.51.
Is it possible to download the firmware (3.51) from the pump? I know it is possible to upload, but I have not found anything about the download.
Can anyone send me a firmware compatible with my version of chromelon?
