Camera Hardware

FACET-II has 6 ORCA-Flash4.0 V3 Digital CMOS cameras (C13440-20CU):

Tech Note

The camera connects to the server via a USB-to-fiber link:

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.
