Mettler M400 communication with Masterflex L/S via DB-25

[questioneronfile777]

I want to use PID control for a pH control loop. pH goes down, pump turn on. I have a Masterflex l/s with a DB-25 cable that I want to connect to a Mettler M400. The pH probe is already functional. I am not sure how to wire this pump for proper functionality, please help!

Hello,
as it turns out I'm wondering the exact same thing, and I'm having trouble reaching Mettler Toledo support. Did you ever get a working solution to your problem?

I did not. After contacting Mettler they told me that this was not possible.
