+------------------------------------------------------------------+ | | | THIS IS THE MASTER FILE SHOWING THE WIRING | | OF TIMING SIGNALS ON MBD AND CTMBD CARDS | | | +------------------------------------------------------------------+ Most Recent Rev. 4-MAY-1995 NOTICE: Although it has not been done in the past (i.e. before 8-NOV-1994) the unused Timing Channel Signal Inputs on the 10H115 line receivers need to be biased to an ECL level so that these unused sections of the 10H115's do not up set the bias in the sections of the 10H115's that are actively transporting Timing Signals. For the MBD's it is suggested that the unsed Timing Channel Signal Inputs to the 10H115 line receivers be connected to Framework Timing Bus Channel #16 i.e. the LED ON signal. For the CTMBD's it is suggested that the unsed Timing Channel Signal Inputs to the 10H115 line receivers be connected to an unused Calorimeter Trigger Timing Bus signal (e.g. Channel #23, #24, or #32).

Nothing is connected to the CBus section. This CTMBD buffers Timing Signals that are used by the L1 Trig's per Bunch DBSC's and as input Terms to the And-Or Network. Because the CTMBD can buffer more signals than are described above; let's also buffer some clock signals for monitoring. CAL. SPECIFIC TRIG.
