&lt;br /&gt;
Notes of the C-RED simulator installation.&lt;br /&gt;
&lt;br /&gt;
A) Powering the computer:&lt;br /&gt;
&lt;br /&gt;
  1. Operating system is xubuntu, which is recommended to use at chara.&lt;br /&gt;
&lt;br /&gt;
  2. It booted directly, without promting the password. I saw the booting was very quick.&lt;br /&gt;
&lt;br /&gt;
  3.  computer name:simu-desktop and user: simu&lt;br /&gt;
&lt;br /&gt;
  4. uname -a, command results:&lt;br /&gt;
  Linux simu-desktop 3.19.0-25-generic #26~14.04.1-Ubuntu SMP Fri Jul 24 21:16:20 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux&lt;br /&gt;
&lt;br /&gt;
  5. lsb_release -a, command results:&lt;br /&gt;
  Distributor ID: Ubuntu&lt;br /&gt;
  Description:    Ubuntu 14.04.3 LTS&lt;br /&gt;
  Release:        14.04&lt;br /&gt;
  Codename:       trusty&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
  8. cred installable sources located at: /home/simu/firstlight/&lt;br /&gt;
&lt;br /&gt;
  chrpath         credonedemo-src-1.0.0.tgz  InstallationLog.txt  libQt5Core.so.5        libQt5Widgets.so.5  uninstall.dat&lt;br /&gt;
  components.xml  credone_mil.dcf            libicudata.so.51     libQt5DBus.so.5        network.xml         uninstall.ini&lt;br /&gt;
  creddemo-src    icons                      libicui18n.so.51     libQt5Gui.so.5         platforms&lt;br /&gt;
  credoneDemo     imageformats               libicuuc.so.51       libQt5SerialPort.so.5  uninstall&lt;br /&gt;
 &lt;br /&gt;
  9. credoneDemo is the real time diaplay executable for the detector.&lt;br /&gt;
&lt;br /&gt;
 &lt;br /&gt;
B) Powering the first light data acquisition electronics:&lt;br /&gt;
&lt;br /&gt;
 The real time display has following buttons:&lt;br /&gt;
 &lt;br /&gt;
 1) Important image acquisition settings&lt;br /&gt;
   a) Build bias and flat. Once they are build there are other clicable options to use them.&lt;br /&gt;
   b) Gain range selection button&lt;br /&gt;
   c) Exposure time (co-add of frames) settings for correlation double sampling (CDS) and single readout modes.&lt;br /&gt;
   d) Image crop option&lt;br /&gt;
   e) Save images buffer allows to acquire detector images with a user selectable number of frames.&lt;br /&gt;
   f) Various image display settings&lt;br /&gt;
   &lt;br /&gt;
 2) PELTIER Cooling system:&lt;br /&gt;
   g) power monitor&lt;br /&gt;
   h) temperature monitor&lt;br /&gt;
    &lt;br /&gt;
C) Data acquisition: By changing the exposure time (or varying the number of frames), test detector images are acquired, for practice.  &lt;br /&gt;
   Test_5000.raw&lt;br /&gt;
   Test_3000.raw&lt;br /&gt;
   Test_1000.raw&lt;br /&gt;
   &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Future work notes&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
1. For first phase, after discussion with John, I understand that we will replace only the detector (in C-RED one; out PICNIC). It means that we will use the existing python GUIs which are optimized for taking the background, plotting the power spectrum and the fringe searching. It means, first, I need to understand the commands working behind the FLI real time display GUI and apply them to the existing MIRC python GUI. Second, the C-RED software currently produces *.raw extension data and that needs to converted into FITS extension.&lt;br /&gt;
&lt;br /&gt;
Also, C-RED data acquisition on a new computer with different camera cards. Optimize the MIRC DAQ software for the C-RED detector array and speed.  &lt;br /&gt;
&lt;br /&gt;
3. Second phase, upgrade and develop more appropriate GUIs in the software practices of CHARA (with GTK software).&lt;br /&gt;
&lt;br /&gt;
3. Third, optics upgrades and so on.&lt;/div&gt;</summary>
