RE: BiRa Ethernet Power Supply Controllers

["Allison, Stephanie" <saa@slac.stanford.edu>]

Hi Rod,

At SPEAR, we use the EPSCs for our main power supplies (unipolar power supplies for quads, bends, etc, that don't need fast control).  The EPICS driver/device support is a bit non-standard (ie, doesn't use asyn - note the controller uses UDP) but works OK, at least on epics 3.14.11, RHEL6-64bit.  The software we use is here in case you want to take a look:
ftp://ftp.slac.stanford.edu/groups/controls/soft/epics/etherPSC.tar.gz
Sorry - there is no documentation in that tar file.  Maybe BiRa provides some documentation.
(I don't know if this is the same software that BiRa provides).

I will forward your email to the SPEAR power supply engineer who can fill you in on more detail.
