Digitizer cards, 40 Mhz bus, RCU, DAQ, Trigger Digitizer cards: 2 types: inner, outer

Digitizer cards, 40 Mhz bus, RCU, DAQ, Trigger Digitizer cards: 2 types: inner, outer 3 ALTROs + Board Controller 3 m bus cable to RCU gave many problems. Solved by changing from 40+50 ALTRO flat bus to 50+80 twisted pair cables. Trigger (LTU) tested DAQ operational. 40 bit signal + 10 grounds CR 7 -FMD, 19 March 2007 adaptor Jens Jørgen Gaardhøje, Niels Bohr Institute 40 bit signal + 40 grounds Twisted pairwise 4
