oSLB HTR Mezzanine Cards

The oSLB cards (optical Serial Link Boards) transmit muon trigger primitives from HO to the RPC trigger
The are the responsibility of The BU Group.

The HO/RPC Trigger is described in NIM A545,97 (2005)
Currently oSLB cards are in design/prototype phase, and are most fully documented in a presentation: Rohlf_060328

Software

As of HCAL release 3.9.9 (or so) the oSLB is supported by hcal xDAQ. It is recognized as a SLB type of the HTR. C++ class documentation (doxygen):

Current Release (on pcephc356 at CERN)
Proposed Changes (on private server at BU)

With apologies for those who dislike idiosyncratic computer code, a command line tool (oslb.exe) for poking around in registers and updating the oSLB firmware is included in the standard hcal distribution. See specification above for details.
