1. Systec CAN-USB Box ― Overview and Status JCOP Team Meeting 2 November 2006 Beat Jost/Cern-PH

2. Beat Jost, Cern 2 JCOP Team Meeting 2 November 2006 History and Motivation ❏ Initially 1,2,4-channel PCI card from KVASER ➢ 5 V until 2006 ➢ 3.3 V (since 2006) ❏ Future of PCI in main-stream server market is not very clear ➢ 5 V is dead ➢ 3.3. V currently still available ➢ PCI-Express (serial PCI) favored (speed) ❏ USB more future-proof ➢ Longer lifetime ➥ Replacement of ‘standard’ components by USB-based equipment –Floppy drives/Memory sticks –CD/DVD drives –KB/Mouse –Parallel port ➢ Hot Plug-’n’-play ➥ Add equipment without opening box and while system is running ➢ Cheaper…

3. Beat Jost, Cern 3 JCOP Team Meeting 2 November 2006 Detailed Specifications and Developments ❏ Multi-port ➢ Many CAN ports per USB port ❏ Rack-Mounted ➢ Natural for racks containing also PCs (horizontal airflow) ➢ ‘solid’ ➥ USB connectors not really suited for rugged environment, but should not be a major problem… ❏ Fan-Free ➢ Low power ➢ More reliable (no moving parts) ❏ Performed a Price Inquiry (development and production) ➢ Systec by far (orders of magnitude) the cheapest (in both aspects) ➢ Development paid by LHCb

4. Beat Jost, Cern 4 JCOP Team Meeting 2 November 2006 Systec Module 16 CAN ports Galvanically isolated 2 USB 2.0 high speed ports 8 CAN ports per USB port Integrated (per port) termination resistors (DIP switches) CAN Outputs Status and Traffic LEDs Termination Resistor DIP switches

5. Beat Jost, Cern 5 JCOP Team Meeting 2 November 2006 Internal Architecture Dual USB  CAN Controller ATMEL A91SAM7A3 CAN 220V AC DC USB 1-4 USB HUB USB 1-4 USB HUB Opto- couplers SMSC USB2504

6. Beat Jost, Cern 6 JCOP Team Meeting 2 November 2006 Other USB-CAN modules ❏ 1, 2, 8 port modules ➢ 1,2 port modules are ‘dangling’ type ➥ Choice of with/without galvanic isolation ➢ 8-port module is table top ➥ Always with galvanic isolation ❏ Based on identical hardware (CAN Controller) ❏ 100% software compatible ❏ Very reasonably priced…

7. Beat Jost, Cern 7 JCOP Team Meeting 2 November 2006 Software ❏ Requirement: Want to run old applications, e.g. OPC servers completely unaltered ➢ Whether using KVASER or Systec ❏ Idea: Implement (parts) of the KVASER API and divert the calls to the Systec library/driver ➢ See presentation of Danny ❏ Also available (standard from Systec) is an interface software between the Systec API and Peak API (ISEG power supplies)…

8. Beat Jost, Cern 8 JCOP Team Meeting 2 November 2006 Status ❏ Software tested and debugged ➢ Many tests done in Crakow (many thanks) ➥ See Jolanta’s talk ➢ some bugs ironed out ➥ multi-user aspects ❏ 30 Modules ordered and received ➢ Most of them distributed ➢ Users ➥ Alice (8 modules, 5 received) ➥ CMS (8 modules, all delivered) ➥ LHCb (currently extensively used by muon group) (~15-20 modules) ➥ (small parts) of Atlas (pixels) (1 module, 1 on loan) ➥ Totem (2 modules) ❏ PCBs for 20 more modules produced ➢ Mounting takes about 1-2 weeks ➢ More modules could be received within 2-3 weeks after ordering ➢ Ordering soon. Please let me know your needs.
