Hello all. Asking for some troubleshooting help, DIY Analytical chemistry, close enough for DIYBio as I'm at my wits end messing with cables and baud rates.
Stringing together an HPLC system and could type out a story or attach my sweet MS Paint diagram of how things are connected, but the real question is, what would cause a machine to respond with gibberish characters when asked it's name in a command line as seen in the picture below?
GSIOC may be Gilson's own serial communication setup, and I know next to nothing about coding etc.
However when I ping the liquid handler or the UV/Vis machine with a "%" command, it returns the modules name and software version number, when I ping the HPLC Pumps with the same command, it returns a different array of gibberish characters each time, or an #error.
I've set baud rates on everything to 19200 which it's defaulted to, or Externally set on the HPLC pumps, no difference.
Perhaps a long shot but didn't know if people that new older serial port machines knew if random giberish was coming up, it's just a bad baud rate somewhere along the line, or something might be out of order.
