Not able to access multiple devices using GSIOC drivers

[azotov]

Hi. Does anybody use LabVIEW Gilson GSIOC drivers. I'm trying to connect to and to control two Gilson pumps. Both pumps are connected to gilson 506 controller. I can access either one of the pumps separately with no problem, but if I'm trying to connect to both, only one connects and works fine, and the other times out.
Simple code attached.

I'll appreciate any help

Thanks a bunch

Hi azoton,

Instead of using one initialize VI, create another one and have the two pumps run in series.
