Hello Lifang,

We’ve been looking at available options of interface equipment to EPICS using serial protocols for the Diamond project. A summary of this work was presented at the last EPICS meeting by Pete Owens

http://www.jlab.org/intralab/calendar/archive02/epics/talks/owens.pdf

It includes links to the serial support we have been using. We are looking to standardise on StreamDevice for simple protocols ie not requiring a checksum and ORNL serial for more complex protocols.

Regards.

Mark

Subject: device support routines for RS232

Dear all,
 
I am developing the device support routines for RS232 Varian Multi-Gauge controller. I use the drivers drvIpac, drvVipc616.c and tyGSOctal.c. Before getting any response(value) from the controller it has to send some commands and I hope to use standard records ai/mbbi/stringin/stringout instead of writing a new record. How to attach the string command("#aa02cnt") in Ai record field to read the pressure? Is it possible that I can share somebody's experience in order to find a suitable way?
 
Any suggestion are appreciated,
 
Lifang
