EMU: CAEN V895 sending values on startup doesn't work consistently

[Tom-Willemsen]

As an instrument scientist on EMU, I would like the CAENV895 ioc to send the correct state on startup.

Currently it only sends the correct state for some channels (e.g. ch49 is ok, ch50 gets set to zero). I think this may be a race condition depending on the order of threshold and "enable" being sent. This results in no counts being recorded for some channels.

This is a requirement for EMU to be able to run IBEX in cycle

Acceptance criteria:

• Restarting the CAEN V895 ioc on EMU puts the CAEN into the correct state.

We should enable asyn traceIO in the driver via st.cmd and confirm all values are being sent as well as the order

questions:

• does the order of enable and threshold value matter
• are we sending all values

It may be a rate issue - labview spawned an executable each set, so was a bit slower

EMU hotfixed and looks to be OK
