====== CUPID Data Acquisition Hardware ======

At FAIR the decision for a DAQ system is based on availability on the market, costs, synergy effects, and performance.
Two possible solutions for SCR DAQ are envisaged. For installations with up to two GbE camera systems the IPC as DAQ host may be used. With higher amount of channels a µTCA solution, 6 slots, is proposed. Those systems will contain an 8 channel GbE switch. 

===== CMOS and Radiation-hardened cameras =====

===== Industry PC (IPC) =====

In case only few channels have to be read out (up to 2), a standard IPC can be used to host the GbE LAN adapter (e.g. dual port) and the FTRN. The IPC operates as standard FEC and will boot via PXEboot its OS.

===== Remote Control =====

For maintenance purposes the MTCA system can be controlled via LAN or IPMI protocol. It provides access to status, temperature, fan speed and powercycle. The system can be surveyed by the REMBRANDT system.
The same type of remote operation is valid for the IPC.
A remote power cycle for the cameras is feasible using the Profinet based Remote Power Control (RPC) system providing a reset pulse to the CPS8 unit.

===== CPS8 =====

Power supply and remote reset for up to eight digital cameras are realized by the in-house developed Camera Power Supply controller CPS8. The CPS8 is based on an Arduino single-board microcontroller and controlled via Ethernet. By sending simple ASCII commands the controlling FESA class sets the power of any attached camera. It can also obtain the power status of each connected camera. In addition, the CPS8 distributes hardware triggers to the cameras either from an external input or self-generated.

CPS8 Controller
  * build in-house
  * Atmel Microcontroller (Arduino) based
  * simple ethernet based access
  * camera power control
  * camera power status
  * camera trigger
    *software trigger
    *hardware trigger distribution
      *currently: all cameras = one trigger
      *future: one camera = one trigger
    *burst mode
  *frontpanel indicators
    *camera power
    *camera exposure (camera strobe output)
  
===== PLC System =====

A Siemens PLC PROFINET IO System (IO controller and devices) controls the aperture of each lens and LEDs to illuminate the target for calibration issues.
A dedicated FESA class using the CERN SILECS library provides access to the PLC from the CUPID GUI via the ACC-Network.

The system will be set up on a 19” DIN-rail holder either close to the SCR DAQ system or in radiation-protected locations inside the tunnel. It is part of the campus PROFINET infrastructure. Plan is, to install a separate stand-alone PLC system for remote power control for all devices.

The bill of material and a schematic overview of the IO System are listed below.
