Server Hardware

We have two Dell R750 servers in B244 rack. They each serve two ORCA cameras.

Product Page

Server OS

The server runs "CentOS7 Lite"

[flaci@cpu-li20-pm05]$ uname -r
3.10.0-1160.76.1.el7.x86_64




Camera Software

We run 'orcaUsbApp' in 'ProfileMonitorApp'.

Current Issues

  • Camera software is not properly integrated into ProfileMonitorApp framework. This issue might explain some of the issues listed below.
  • Save/restore does not work. It appears that the IOC does not know the path to the data. This might be fixed?
    • Ask Jeremy
  • Some PVs readback value does not match the set value, and this can cause issues with Matlab HLAs.
    • CMOS:LI20:3505:BinX(Y)_RBV
    • CMOS:LI20:3505:DataType
    • This might be fixed? Ask Jeremy
    • ROI doesn't work with profmon_gui or DAQ
    • Need intergration into watchdog and emit IOC for new channel 3516

Less Urgent Issues and Feature requests

  • The camera serial number is hardcoded in the IOC st.cmd. This means that if you replace the camera, you have to edit the IOC at the line "epicsEnvSet("SER","305053")

  • If the camera fails or becomes disconnected from the IOC, this is not reflected by the "ASYN.CNCT" PV, but it works for the GigE cameras.
  • Event2 integration.

Bin X/Y RBVs are purple because they have been manually overwritten.
