---++ LTC external trigger connector

   should be connected to the PCB as shown in the picture:
     <img src="%ATTACHURLPATH%/dscn4726-small.jpg" alt="dscn4726-small.jpg" width='778' height='583' />

   and fitted to the front panel as shown here:

---++ <nolink>G3TTCrx</nolink>

   * Seems not to transmit B broadcast frames with data content equal to 0x00
   * Seems to swallow the lowest to bits (i.e. set them to zero). Bit 0 is BC0, bit 1 is EC0 (Event counter reset)
   * G3 PCI card: EP 680-1125-500-A (UNI_PCIB), see also [[http://dgigi.web.cern.ch/dgigi/fed_kit/fed_kit.htm][D.Gigi's FEDKIT page]]

   * Jumper settings (derived from schematics), jumper set means logic 0 (connected to GND)
     unless where otherwise specified. Vcc is 5 Volt in the schematic, QPLL supply voltage is 2.5 Volts,
     thus pins connected to half of Vcc are set to logic 1.

   | *Jumper* | *signal* | *description* |
   | ST3 | MODE | frequency multiplication mode (depends on external crystal) |
   | ST4 | FREQRANGE0 | jumper set = 1 |
   | ST10 | FREQRANGE1 | jumper set = 1 |
   | ST9 | FREQRANGE2 | jumper set = 1 |
   | ST8 | FREQRANGE3 | |
   | ST7 | RESET | active low: 0 (jumper set) = reset, 1 (jumper missing) = normal operation |
   | ST5 | EXTCONTROL | jumper set = logic 1 = frequency selection lines used |
   | ST6 | AUTORESTART | 1 (jumper missing) = automatic recalibration |

   * The QPLL locked information can be probed (e.g. with a scope) as shown in the following picture:

---++ TTCSoftware release procedure

   * Make sure the files TTCSoftware/releasedate and TTCSoftware/buildversion are updated !
     (edit buildversion by hand and run utils/updateReleaseDate.py)
   * Run the following (you need to use the proper version number):<br/>
     <pre>
      export VERSION=6.06.02 ; \
      export CVSTAG=$(echo $VERSION | perl -npe 's/\./-/g; $_ ="v$_";') ; \
      rm -f /tmp/TTCSoftware-${VERSION}.tgz; \
      ./utils/maketgz.py --cvstag=${CVSTAG} /tmp/TTCSoftware-${VERSION}.tgz && \
      ./utils/testRelease.py --xdaq-root=/opt/xdaq /tmp/TTCSoftware-${VERSION}.tgz
    </pre>

    (note that the option =--xdaq-root= can be specified more than once to test against multiple
     XDAQ releases [this was done for SLC3 as we had the RPM installation and the older one]).
---+++ RPM building
   This assumes that you have created a source archive as described
   in the previous step.

   * on the development PC, assuming the source archive is
     =/tmp/TTCSoftware-xyz.tgz=, do the following (after having
     adapted the version number):

     <pre>
       export VERSION=6.06.02 ; \
       ./utils/makerpm.py \
         --no-python \
         --version=${VERSION} \
         --source-archive=/tmp/TTCSoftware-${VERSION}.tgz
     </pre>

     This will produce a binary RPM as well as the source RPMS. 
     The =--no-python= option is used at the moment because the
     RF2TTC code causes problems (segmentation faults at building time
     !) if the corresponding python bindings are built.

     Copy the source RPM to the distribution area in AFS and
     to the online cluster in =~ttcpro/ttc-rpms/srpms=.

     To
     produce the binary RPM for the online cluster, we recommend
     taking the SOURCE RPM to the online cluster (as the xdaq version
     might be slightly different there) and rebuild the RPM, using

     <pre>
       export XDAQ_ROOT=/opt/xdaq 
        rpmbuild --rebuild ~ttcpro/ttc-rpms/srpms/TTCSoftware-x.y.z-a.src.rpm

     </pre>

     (yes, building the binary RPM on the development PC could be left
      out).

    
---++ RRD Tool

 how I installed RRD tool (on SLC4):

   * installed the following rpms:

       <pre>
         perl-rrdtool-1.2.15-1.el4.rf.i386.rpm  
         rrdtool-1.2.15-1.el4.rf.i386.rpm  
         rrdtool-devel-1.2.15-1.el4.rf.i386.rpm
       </pre>

     (get them from here: http://dag.wieers.com/rpm/packages/rrdtool/)

     Do *not* install =python-rrdtool-1.2.15-1.el4.rf.i386.rpm= as this causes problems.

   * get the python binding module: http://downloads.sourceforge.net/py-rrdtool/py-rrdtool-1.0b1.tar.gz?modtime=1158141535&big_mirror=0
      * unpack it
      * install it using =sudo python setup.py install=


---++ Triggersupervisor

---++ TTCci <nolink>L1A<nolink> from BGO:

   * When configuring a BGO to be a 'short B frame' followed by one trigger, the trigger seems to come at BX = BX(B frame) + Delay2 + 6
   * make sure that the BGO is configured as a double command !
   * on the main config page: Enabling 'SCOM' as trigger source seems to be sufficient, enabling 'BCHANNEL' on the other hand
      seems NOT TO WORK !!

---++ SLP stuff

   * copy =/etc/slp.conf= from e.g. =vmepcS2g17-04.cms= (this contains a line <pre>net.slp.DAAddresses = 10.176.29.112</pre>)
   * after modifying =/etc/slp.conf=, the slp daemon needs to be restarted: =sudo /etc/init.d/slp restart=.
   * check whether any services on the TTC pcs are registered: =slptool -i $(hostname -f) findsrvs service:peer:http | grep -i vmepcs2b16=


---++ Frequency meter

(Preliminary) database table:
<pre>
CREATE TABLE cms_ttc_pro.mon_freqmeter
(
  FREQUENCY INTEGER NOT NULL,
  TIME    timestamp(9) DEFAULT sys_extract_utc(systimestamp) NOT NULL
); 
</pre>

To plot offsets with respect to 40079000:
<pre>
CREATE OR REPLACE VIEW mon_freqmeter_offs AS
SELECT frequency - 40079000 freq_offs, time
FROM mon_freqmeter;
</pre>

---++ ORACLE stuff

---+++ Dumping the trigger key database
   * From lxplus (with bash/zsh):
<pre>
   export ORACLE_HOME=/afs/cern.ch/project/oracle/linux/prod
   export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
</pre>
   * create an ssh tunnel with e.g. a lifetime of 10 minutes (600 seconds):
<pre>
   ssh -L 10121:cmsonr1-v.cms:10121 -fN cmsusr0b 'sleep 600'
</pre>
   * run =exp=:
<pre>
