Hi Heinrich,

If the data is fixed, I would suggest to use StreamDevice (http://epics.web.psi.ch/software/streamdevice/) with a bo record or similar. The actual record type does not really matter when no changing record content should be written.

Another possibility is the attached array support that allows to initialize an array from a file.

Hi

I have an octet device. (asyn driver)
It sends commands to some hardware. Now if I send a certain sequence of
chars to the device I can perform some stuff. e.g. reset the device. Or
set a certain mode. - things that will correspond to buttons on the user
interface.

So I like to setup a waveform record with the necessary data inside as
default. And then only trigger the PROC field so that the data be
written to the device.

My only question is - how do I specify this binary data to the waveform?
for example how do I setup a waveform with CHAR data: 00 01 08  or
something like that?

does the waveform things also read once at start up with asyn? even if
it is a write only command?

thanks
-Heinrich
