Re: EPICS interface for Edwards nXDS scroll pump

[Florian Feldbauer via Tech-talk <tech-talk@aps.anl.gov>]

Hey Ray,

we are using an nXDS scroll pump from edwards and controll it via StreamDevice + Asyn via the RS485 interface.

I've attached protocol and database files.

HTH,

Cheers,
Florian

Hello,

Has anyone developed an EPICS interface to the Edwards nXDS scroll pump?
