Cold start instructions                                 Rev. 12-AUG-2005
-----------------------


These are supplemental instructions for the expert to use while cold
starting both the TFW and the L1 Cal Trig after a power outage.


    We are running:  TRICS  V10.5.E

Overview:

    Only after Master Clock is running and loaded,  then turn on TFW and
    then the L1 Cal Trig  (one power supply at a time)  then:


    Configure FPGA's.   Use the normal TRICS  "Master Command File" menu
    for this.  It configures all FPGAs except for the M101 Routing Master
    and the M101 L1 Cal Trig Quad Term Generation.


      Configure the L1 Cal Trig Quad Term by:

         1) Use the bottom section of TCC's "Configure FPGA's" menu to
            "Execute" the dcf file that configures the L1 Cal Trigger's
            Quad Term FPGAs.  The dcf file to use is:

                D0_Config\M101_Quad_Term.dcf

            The button to take you to the "Configure FPGA's" menu is
            at the upper right hand side of the TRICS main menu.

            Note: that in the past configuration of the Quad Term FPGAs
                  was optional but that with the latest beam physics
                  trigger lists the Quad-Region Term FPGAs are needed.
                  Configuration of the Quad-Region Terms is now a must.


      Configure the Routing Master FPGAs by:

         1) After the Routing Master is powered up, wait for its
             SBC to boot (less than 1 minute)

         2) From an online machine run 'l3xdaq_stop RM' which will
            stop the relevant readout processes in the Routing
            Master's SBC (and thus give TCC exclusive use of the VME
            bus in this crate to Configure the FPGA's in the RM).

         3) Use the bottom section of TCC's "Configure FPGA's" menu to
            "Execute" the dcf file that configures the Routing Master
            FPGA's.  The dcf file to use is:

                D0_Config\M101_Routing_Master_All.dcf

            The button to take you to the "Configure FPGA's" menu is
            at the upper right hand side of the TRICS main menu.

            When you "Execute" the file
            D0_Config\M101_Routing_Master_All.dcf   you will likely see
            an error reported in the TRICS log file on the left hand
            side of the screen.  That is caused by previous VME cycles
            interfering with TCC's attempt to Configure the Routing
            Master's FPGA's.  Just execute this dcf file a second time
            and it should run error free.

         4) Finally, from an online machine run 'l3xdaq_reset RM' which
            will restart the RM software running in this SBC.



    Use the TRICS  "System Control Status"  menu to:

       Set the L1 Cal Trig Eta Coverage to 1:20   You need to click
       "Set This Coverage" after entering the desired coverage values.


    Do a Full Initialize of TFW and L1 Cal Trig.  Currently L1 Cal
    Trig will show some errors at TT eta 17 and above because some
    components that are not needed for normal operation have been
    pulled out  (to save heat load)  but TRICS is still trying to
    talk to them.


    Use the TRICS "Master Command File" menu "Run a Master Command
    File" option to select and then execute the file

        \D0_Config\Load_L1Cal_GainsPeds.mcf

    This loads the current Gains and Pedestals into the L1 Cal Trig.


    Use the TRICS  "System Control Status"  menu to:

       Set the L1 Cal Trig Eta Coverage to 1:16


    Do a Full Initialize of the TFW and L1 Cal Trig  verify that
    it is a clean error free initialize of all parts.



For reference only, the current Gains Ped's files are:

    D0_Config\Gains_17_20_1_32_rev_a.tti             #  TT eta  17:20
    D0_Config\Gains_1_16_1_32_rev_5.tti              #  TT eta   1:16
    D0_Log\Find_DAC_V10_5_E_20041202_Edited.tti;3    #  TT eta  17:20
    D0_Log\Find_DAC_V10_5_E_20041202.tti;2           #  TT eta   1:16

These are the files loaded by Load_L1Cal_GainsPeds.mcf above.
