  1. Wuppertal Readout Chain Kendall Reeves Bergische Universität Wuppertal

  2. The Pixel Readout PPO Electrical  Optical Back-of-Crate Card (BOC) Optical fiber Typ 0 Pixel Opto- board Readout Driver (ROD) S-link German Pixel Meeting, Dortmund, 13 Nov. 2003

  3. In Hand: 4 Modules Optical BOC, with S-Link card ROD, Rev. C PC as ROS, with S-Link PCI card. Still Needed: PP0 (promised from LBL) PP2 (Prototype coming from Milano) Optoboard (promised for this week) ROD, Rev. E (expected by end of November) Status German Pixel Meeting, Dortmund, 13 Nov. 2003

  4. Test Setup Crate Control via SBC (Cern Redhat 7.3.3, rodtest as control program) or National Instruments VXI controller (Windows 2000, Teststand as control program, still being commissioned). German Pixel Meeting, Dortmund, 13 Nov. 2003

  5. ROD/BOC No back plane, so single connector SLIDAD mounted on BOC (S-Link Infinite Data Drain) Current efforts revolve around test Procedures detailed in “Procedures for Standalone ROD-ROL Testing”, document ID ATC-TD-TP-0001. Requires fully operational version of Teststand – next week, at the latest, with visit from Lukas Tomasek or Jan Walenta. German Pixel Meeting, Dortmund, 13 Nov. 2003

  6. ROS (Readout System) Commercial Desktop PC with: • Dual processor (1.8 GHz Xeon) • 2 GB Memory • 800 GB RAID 0 array (~10 min. full throttle DAQ). 2 masters (400 GB) – marginally acceptable performance. German Pixel Meeting, Dortmund, 13 Nov. 2003

  7. ROS II (Readout System) 4 disks (800 GB) – degraded performance. Note that this is an initial test under Windows 2000, with Linux foreseen as the DAQ OS. German Pixel Meeting, Dortmund, 13 Nov. 2003
