Does anyone have any experience running an LC-20AT pump via Chromeleon? I have a couple of AD and AB series pumps that work fine via serial connection but I'll likely need to use the ethernet style connection for the AT pump based on the computer hardware. (All of my serial ports are filled.)

The AB pump had to be run as a 10 series AD in order for Chromeleon to recognize it. Any tricks that might help make installation easier are appreciated. Also, the pump specs describe it as being able to do 2 or 3 solvents. Is the 3rd solvent line an add or or standard issue with all ATs?

Thanks!
