Re: pfeiffer TPG 366 Maxiguage Epics support

Hey Vishnu,

we use a lot of Pfeiffer equipment and usually use StreamDevice + Asyn for it.
Attached are examples for the TPG 256.

HTH,

Dear All,

     I have Pfeiffer Vacuum gauge  controller TPG366. I would like to read data on serial port(RS-232). 

Any one using TPG 366 epics driver and can share with me, I will be very thankful.

Thank you
