Hi Greg,

We are testing Andor Zyla with PCIe on Linux to capture images at 20 Hz. Although we haven't tested much yet, we can discuss what's happening.

Cheers,

Sourabh

Hi all,
We have published a new official version (v1.3) of the oac-tree bundle, referring to tagged commits of each package. See https://urldefense.us/v3/__https://github.com/oac-tree/oac-tree-bundle/blob/master/VersionInfo__;!!G_uCfscf7eWS!eilV2FSf_qJVg4nmw8S903Lp5t7bqoqVvsUYXuAUzgVvucF8o89XyH3_bc2BOyrRLDc6U3HW1eXN2ecDxICCVRC7ZIn2uA$  for all the tags of this bundle.
Documentation was also updated: https://urldefense.us/v3/__https://oac-tree.github.io/oac-tree-docs/__;!!G_uCfscf7eWS!eilV2FSf_qJVg4nmw8S903Lp5t7bqoqVvsUYXuAUzgVvucF8o89XyH3_bc2BOyrRLDc6U3HW1eXN2ecDxICCVRCHesqADQ$
This release contains:

  *   Minor fixes (e.g. compiler warnings)
  *   Support for documentation entries in variable/instruction registries, allowing user interfaces to automatically display these
  *   GUI changes:
     *   The GUI now includes a new editor that lets you view and edit multiple sequences side by side.
     *   The NodeEditor also introduces an experimental mode that visualizes the execution flow in real time.
Let us know if you encounter any issues with this release or in general.

Best wishes for the new year!

Walter

Hi William,
to communicate with BACnet we are using the epics BACnet:

Hello,

I?d like to ask the list if anyone has experience operating Andor cameras using the PCIe frame grabber card on Linux.  We are using RHEL9, but any Linux experience might be helpful.  Direct contacts with Andor have not been very fruitful in resolving the issues that we are seeing when attempting to use the PCIe card.

Best regards,
Greg Guyotte
