After a battle to sort out the networking issues with the APC (on loan) and PDU, able to get all working fine, and logged in separate Elog.

The ability to power cycle XRM proved essential as periodically something is happening in the tunnel which causes the network connections (both for XRM and APC) to get cycled.

While the APC can simply be logged into again, XRM requires a reprogram/reconfig cycle.  Interestingly, the link comes back and registers can be read back.

But data taking/writes either are ignored or cause the link to become bricked.  It could be an ARM stop, where some type of soft reset might work.

Anyway, without proper alignment fiducials, were scanning blind.  To try and see something, the mask was removed. hitting the detector with ribbon of x-rays.

Clearly seen in the first attachment.

A zoom in for the 4 pixels being read is shown in the second attachment. 

Obviously some signal processing is going to be needed to deal with the AC-coupled nature of this signal, and possibly induced ringing. 

However the Signal-to-Noise is encouraging, as the amp board is running at minimal gain.
