Cables are numbered from 1 to 8 , 1 being the shorter one. On the crates they will be specular:
left 1-2-3-4-5-6-7-8 right 8-7-6-5-4-3-2-1 from first channel on the right
Labels can be fixed around the cable with some transparent scotch
Test of the soldered coil at 10 bar with water before mounting on the SM.
Test of the complete system with air pressure at 1 bar, including the distribution, once the assembly in the SM is completed.
Test of the complete system at 10 bar with water.
More details on the use of the pump for the test will follow.
Gas system tests
Here follows instructions for the gas system test of the SM. Please write all steps in the traveler for the SM
After insertion of the modules check gas tightness using the good gas at 6 mb (a dedicated line has been prepared from the second gas rack
distribution). The measurement is sensitive to the atmospheric pressure and temperature so it should be made in a relatively short time range ( 10 -15 min) to reduce such contributions.
If you suspect there is air in the tube, please purge it. The measurement takes some time since the gas flow is low.
Write the values in the travelers
Check at 1 bar the connecting tube + distribution panel with air.
The check should be done independently for each line and no leakage should be measured. If ok,before connecting to the module, briefly flush it with good gas to avoid air going into the modules.
NB in SM1 this test was merged with the following since the distribution panel was mounted at the end.
After connection with the module check that each line is ok observing the output bubbler.
At the end of the SM assembly, repeat the leakage test for each module independently and compare with first measurements.
Each TOF VME crate is controlled through the SY1527 located on top of VME cosmic crate.
The real power (48 V) to the crate is given by a big power supply A3485A ("Maciste"). Additionally a 48 V power for service
purposes is maintained by an external power supply (located on the top level of the tray where the Maciste stays).
Before to hardware action on the crate the 48 V service MUST BE SWITCHED OFF. Please remind always, while handling
the flat cables from Maciste to crates, that these cables bring a 48 V line. Any wrong (or live) insertion can produce
serious damage to the electronics.
The SY1527 name is caentoflv1. You can connect to it from a shell using the command:
> telnet caentoflv1 1527
user: user
pswd: user
On menu MAIN you select Channels Use only if needed the telnet interface and remember to logout. Don't leave a session opened and unattended. There is a limitation to only 5 sessions.
A nice graphical interface is available through one of the two Windows PC in the small room at the center of 167 area. This interface can be also reached (from pctofsm and pctoflab1) using the command
> dcs
(ask the password of user alitof to one knows it).
The right sequence to power-up the crate after any hardware operation is the following:
check all cables are rightly connected (48V service, comunication with SY1527,48 V power cables from Maciste to crates)
then turn ON the 48V service power supply
on the MAciste front panel turn ON the controller enable and the channel switcher that are in use
log on the SY1527 and check Maciste and A1396 are connected (not unplugged) switch off relevant VME slots
switch ON the 100A channel (the Maciste power) Ch# 0.01.029 (for Ch00 ) Ch# 0.01.059 (for Ch01 ) Ch# 0.01.089 (for Ch02 ) (look the in the front of maciste it must be turned on the proper switch )
then switch on the 5V and 3.3V channels on the selected VME crate
then switch on the VME slots you are interested to test
The right sequence to shutdown the crate before of any hardware operation is the following:
log on the SY1527 and switch off relevant VME slots
then switch off the 5V and 3.3V channels
then switch off the 100A channel (the Maciste power)
then turn off the 48V service power supply
LV CHANNEL MAP
In this section please insert LV channel map setup for each supermodule. A good job would be also to record all the FEA LV values measuring the voltage directly on the FEA. This will help in an eventual future intervention on LV settings or if any sort of LV calibration is needed. You can find an add-on for the SM traveler concerning all the LV setup exactly here.

LV SuperModule 2 (SM0 but SM8 in the old wiki page)
Remeber: in the following measurements LV channel is the CRATE channel. The corresponding FEACS are sorted starting from the CRATE to the centre of the SuperModule. NdR+
Every TRM before to be inserted inside a SM crate must be validated in the test facility (Electronic Test Room). Use PC ''pcdaq2'', account ''labdaq''. This work is currently made by Alessandro, Pietro and Stefano.
TRM Test Instructions
Check all power supply are turned off
Check that in the backplane this card disposition is present
Connect the TRM test board with the two 1.50m Cables to the HPTDC test distributor and the HPTDC test distributor to the inputs of the TRM under test
Turn on the 5 A power supply (5 v ) (the little one) then the 40 A power supply (3,3 v) (the big one)
Run ''~/VME/TRM/trmtest'' as user ''labdaq'' in ''pcdaq2''
Follow the instructions of the program and change the cable TRM test board upper cable (1.50m) with the 4.50 m long amphenol cable and finish the test.
after finishing the test replace the 4,50 m long Amphenol cable with the 1.50m labeled Test Board Upper
Amphenol shell receptacle of the connector, which is magnetic, has to be extracted for the TRMs delivered so far. The procedure is as follows:
Ordered List Item
TRM insertion
Filling a crate start ALWAYS from SlotID 12 and the to the upper one.
Before to insert a TRM inside crate for its final insertion use the following check list:
the crate must be OFF. Turn off all digital channels (3.3V and 5.0V), turn off Maciste channel (100 A), then finally turn OFF 48V SERVICE power supply (the last cannot be done remotely). More detailed info about crate power cycle are published below in section Crate Power On/Off
the card have to be tested in lab test facility. APA firmware must be at least 0.0 and micro firmware version must be at least 1
CLK connector must be selected to EXT
the three selection jumpers (NFAULT, DATA READY and PROG) must be selected according the VME slot the card is in
the card locks should be slackened, but not too much (risk to loose the last piece!)
During the insertion: * the insertion is tight: especially some resistors and capacitors can be damaged. Put a mylar film on the bottom side, to protect the resistors. Extract the mylar film once the insertion is completed. * the insertion is tight: proceed to screw in the screws from both sides. If you encounter resistance please DO NOT FORCE and check the insertion of the VME connectors on the backplane. Start to screw in by hands in such a way to don't force. Use screwdriver when you are sure card is correctly inserted. * at this point don't lock yet the card locks * at this point don't connect yet the signal cables
After the insertion:
connect the clock cable from CPDM to the just inserted TRM. If necessary (loosy connection on CPDM side) remove some piece of thermoadesive from the Tyco connector side. The connector on the CPDM side must be not extracted easily.
turn on the power in the following order:
turn on 48V service
turn on Maciste channel
turn on 5V then 3.3V
be sure the CPDM slot is ON (slot # 3 in crate Right)
turn on the slot just inserted: check the increase of current in 3.3V channel is around 9-10A
log on //pctofsm// (account //toftest//) and do the following commands:
''scancrate'' (check the TRM just inserted is correctly seen)
''scanhptdc'' (check the TRM just inserted passes all the checks performed)
''trmtest '' (check the TRM passes all the checks performed)
if all tests are passed: screw the card locks
update TRM map ID below
TRM MAP
In this section please insert TRM ID (read in the blue small front panel near the right screw) inserted for each supermodule.
Once a TRM has been inserted, connect properly a CLOCK cable to the TRM. Then turn its slot on. Be sure the clock is in, e.g. the CPDM inside RIGHT crate must be powered. Check also the optical link is powered and working.
scancrate
Use tofbaby and do the following commands
> cd SOFT/TEST> ./scancrate -c [Crate Nr.]
This program check which modules are in and look for TRMs. Typical output is as follows:
[tofbaby] /home/toftest/SOFT/TEST > ./scancrate -c 0 ALICE - TOF Crate Test Facility on Crate # 0 Slot # 02 LTM Present (Got VME data 0x55555555) Slot # 03 TRM Absent (BERR detected) Slot # 04 TRM Present (Got VME data 0xAAAAAAAA) Slot # 05 TRM Present (Got VME data 0xAAAAAAAA) Slot # 06 TRM Present (Got VME data 0xAAAAAAAA) Slot # 07 TRM Present (Got VME data 0xAAAAAAAA) Slot # 08 TRM Present (Got VME data 0xAAAAAAAA) Slot # 09 TRM Present (Got VME data 0xAAAAAAAA) Slot # 10 TRM Present (Got VME data 0xAAAAAAAA) Slot # 11 TRM Present (Got VME data 0xAAAAAAAA) Slot # 12 TRM Present (Got VME data 0xAAAAAAAA)
in this situation all TRMs are in and this is a right crate (CPDM in slot 3 doesn't give VME response)
scanhptdc >./scanhptdc -c [Crate Nr.]
This program performs various tests on TRM. The final status should be "PASSED". Typical output:

= press any key to continue
The STATUS is OK only for firmware release 4, but the most important thing is that the program check the Fail Bit value; if it's set to 1, the program automatically switch it to 0. With this bit set to 1 you can seriously damage the TRM turning it ON without the clock. checkmblt
This program test data bus integrity when working in DAQ mode (Multiplexed Block Transfer)
[tofbaby] /home/toftest/SOFT/TEST > ./checkmblt -c [Crate Nr] [TRM list]
for example to test VME bus after insertion of TRM card in slot 5, in crate 1 use:
[tofbaby] /home/toftest/SOFT/TEST > ./checkmblt -c 1 5
To run a test on whole crate 0, use:
[tofbaby] /home/toftest/SOFT/TEST > ./checkmblt -c 0 3 4 5 6 7 8 9 10 11 12
This program cannot work on LTM (slot 2)
Trmtest >./trmtest -c [Crate Nr.] [Slot Nr.]
Then use on any TRM installed the program ''trmtest'' and follow all steps. To check TRM in slot nr. 4
do the command:
>./trmtest -c 0 4scanbus >./scanbus -c [Crate Nr.] [Events] [Slot Nr.]
At this point performs a test on data bus using the command:
[tofbaby] /home/toftest/SOFT/TEST > ./scanbus -c [link Nr] [events] [slot list]
for example to test VME bus (100 events) after insertion of VME card in slot 5, in crate 1 use:
[tofbaby] /home/toftest/SOFT/TEST > ./scanbus -c 1 100 5
To run a test on whole crate 0, use:
[tofbaby] /home/toftest/SOFT/TEST > ./scanbus -c 0 1000 2 4 5 6 7 8 9 10 11 12
This program can work either on LTMs and TRMs.
TRM Manual Controller
In case of trouble, it exists a TRM manual controller, which can be invoked by the command:
>trmcTRM test program facility A) Trm Slot [04] | P) Test Pattern [0x000001] | E) Event Gen N) Cycles [0d00000001] | X) Cross-Talk test | I) INL R) Read a register | W) Write a register | Q) Quit S) Save User Conf. | T) Read Trig Setup | M) Access to Micro 8) Set Patt8 | B) Read Event | C) TRM Clear Y) My setup | K) Consistency check | D) Scan IDCODE H) Scan temp | L) Acq Loop | P) Set Acq Par Z) Update Setup | J) LTM Temp | F) Read Flash Page 9) Write Flash Page | 0) Toggle Status Chain A | 1) Toggle Status Chain B Control: 0x000A | Status: 0x383C | Ev. Stored: 0x0000 | APA FW: 0000 | MicroFw: 1 (14/07/06) Chain A Status: 1 1 7FFF 0000 FFFFFF FFFFFF FFFFFF FFFFFF FFFFFF Chain B Status: 1 1 7FFF 0000 FFFFFF FFFFFF FFFFFF FFFFFF FFFFFF
it is designed for experts. However the most common use of it is to turn on chain A and B,
if found OFF (this can be seen by the program ''scanhptdc'').
To turn on a chain use option 0 or 1 (Toggle Chain Status) and then use option Z.
TRM firmware re-programming validation
Before to start cabling a last check to be done (mandatory) is the whole procedure to reprogramming firmware remotely. This has to be done inserting the DRM prototype Altera in slot 1 (instead of V2718 board). The following hardware has to be deployed:
a small hub
connect Eth0 connector in DRM to one port of the hub
connect the second network card of pctofsm (or pctofdaq1) to the hub
A private eth network will be setup. (pctofsm or pctofdaq1 eth1 have IP 10.0.7.1, the DRM has IP 10.0.7.46)
Insert the DRM inside slot 1. To do that remove upper panel of the crate to drive the insertion with hands
Connect to the DRM the following cables:
ethernet cable to the hub (use connector input ETHERNET on DRM and use special network adapter with transformers)
clock cable from DRM (input connector ALICLK)
optical fibre from V2718
Turn 5V, 3.3V and then CPDM (slot 3) and DRM (slot 1). If you are in a LEFT crate turn on before the CPDM of the RIGHT crate.
on the crate turn ALL the TRMs. If LTM is not inserted turn on in any case also slot 2.
check using ''scancrate'' and ''scanhptdc'' everything works. If not you could need to turn oof and on the DRM again
Then connect to the CPU inside DRM
pctofsm> telnet drma1500
(user: root, nopwd) at the prompt give the following commands:
# df# cd /home/tof# ./tofstartup.sh
You should see an output like:
ALICE-TOF specific startup ...loading DRM device driver to access VME and JTAG buses rmmod: DRM: No such file or directory Using /home/driver_Rev0/DRM.o Module Size Used by DRM 3888 0 (unused)
on ARM CPU prompt then give the following command:
# ./Upgrade 4
You have to run twice this comand. Check the message. The program should read firmware version and internal FPGA ID code. A normal result is something like:
# ./Upgrade 4 ******************* SLOT 4 ******************* TRM not responding to the VME access ID Code = 014101CF # ./Upgrade 4 ******************* SLOT 4 ******************* Found TRM with FW-Rev 4 ID Code = 014101CF
power on the VPP channel. It MUST be ON and not in Fail. If VPP is off the comand below can seriously damage the hardware.
give the command (right or left depending on the crate):
#./upcrate_left.sh
or
#./upcrate_right.sh
The whole programming takes (without any error) around 1 hour and 20 minutes for the
left crate (something less for right crate).
check the programming is going on. The TRM under programming has its led OFF. For every card a log file name is created (upgrade4.log for card 4 ecc. from 3 to 12). A normal completion of the reprogramming has the following output:
when the reprogramming is finished check all the log files. A useful command to check all files is (from pctofsm or pctofdaq1 depending on where you are connected):
pctofsm> cd /home/tofpctofsm> tail upgrad*.log | egrep "==>|ex_code
If for some card the ex_code is bad and programming is failed try again with the individual command:
# ./Upgrade -f V1390trm0004.stp
if it fails again contact Pietro. Please take note carefully of the Res and ex_code value in the case. The TRM has to be removed from the crate.
when everything is done, REMEMBER TO TURN OFF VPP
check again all TRMs with ''scancrate'' and ''scanhptdc'' command.
Pulser procedures with V2718
The pulser procedure is operated from pctofsm.
The PC has to be connected to the crate(s) through optical fiber(s). A V2718 modified has to act as VME controller.
pctofsm has two optical fibers: use LINK 0 to connect to crate Right and LINK 1 to crate Left.
In the CPDM front-panel there are three sections for pulser lines:
All pulser lines outputs (LEMO connectors) of CPDM should be rightly connected.
Additional cabling for pulser
It is currently possible to test Central/Interm. module and then External Module. It is not possible to pulse simultaneously all the three sections.
Required cabling to pulse Intermediate and Half-Central Module:
insert a LEMO cable in the empty output of section PULSE1 of CPDM. This line should be delayed (use the delay box available) and inserted in DSn connector of V2718 card (the DSn connector is the one farest from the optical connector in the V2718 card).
Required cabling to pulse External Module:
insert a LEMO cable in the empty output of section PULSE0 of CPDM. This line should be delayed (use the delay box available) and inserted in DSn connector of V2718 card (the DSn connector is the one farest from the optical connector in the V2718 card).
Software control
Log on pctofsm (account toftest).
To check signals output from CPDM with a scope you can use the command:
> pulser
where can be 0 or 1. 0 corresponds to section 0, 1 to //both// sections 1 and 2. A 50 ns long pulse, positive, with height around 5 V should be visible. The pulse frequency should be 1 Hz (jitters can happen due to PC overhead).
The pulser program must NOT be active while taking pulser data with DATE.
Threshold adjust
If you want to adjust FEA thresholds (through LTM) edit the file ''/home/toftest/sm/configurationFiles/SOR.commands''. Look at line:
{DATE_SITE}/${DATE_HOSTNAME}/ltmcmd 0.5
the last value is the threshold set (in V) inside FEA. Change this value to the preferred one.
You always pulse using CPDM in Right crate, but it is possibile to read out TRMs in Right or in Left crate.
Right Case
* You need to power on just the Right crate. Connect optical link 0 to crate Right.
* Execute the following command: ''> confRight''
* The LEMO cable from CPDM to V2718 card should be connected to V2718 card in crate Right.
Left Case
* You need to power on both the Right and Left crate. Connect optical link 0 to crate Right and optical link 1 to crate Left.
* If you have cooling problems, take into account that in Right crate you can just power on 5V and slot # 1 and slot # 3.
* Execute the following command: ''> confLeft''
* The LEMO cable from CPDM to V2718 card should be connected to V2718 card in crate Left.
To start an acquisition run use the command:
> daqControl
and then the usual DATE interface will start.
Required software configuration to pulse Intermediate and Half-Central Module:
edit the file /home/toftest/sm/configurationFiles/equipment.config. In the Trg equipment edit the last parameter (last of seven). The seventh should be set to 1.
Required software configuration to pulse External Module:
edit the file /home/toftest/sm/configurationFiles/equipment.config. In the Trg equipment edit the last parameter (last of seven). The seventh should be set to 0.
Run operation
When the DATE run is started data are recorded in /testdata/pulse_.raw. Please consider the following:
the run proceeds at maximum rate and produces a lot of data. Consider to stop the run when enough statistics is taken.
when run is terminated could be safe to rename data files as pulse_SM_Cr_E.raw and pulse_SM_Cr_IC.raw with self-explanatory meaning (E: stands for external module, IC: for internal/central module) and copy them in /DATA/pulser/.
Data analysis
Use mood. To be written by Roberto. At the moment see the previous DAQ section (the one written for cosmic test).
Noise rate measurement
Using more or less the same procedure described for the PULSER test it is possible to perform a noise-rate measurement on the supermodule. The idea is to run the DAQ without HV and without any pulse active, that is without any expected signal coming from the FEAs.
To do that we have however to send a trigger pulse to the V2718 in order to acquire data. So an easy way in order to do this could be performed by sending a random TTL pulse to the V2718 with an external pulser.
Notice that during the data acquisition all the FEAs have to be powered.
Another important thing is the TRM matching window and the number of collected events: in order to detect noises with rate greater than 1Hz at least 1 Mevents have to be collected with a matching window of 1 us.
To set up the TRMs in this way just use
noiseRight
noiseLeft
(please note that these two commands work only on pctofdaq1) for Right/Left crate and set up in DATE the number of events. Even more important is the threshold value which I propose to set at 1.0V as a standard threshold value for these kind of measurements.
Once data have been collected, following the PULSER file names, rename the data file as
noise_SM_Cr.raw
and put it into
/DATA/noise
directory.
Actually, since the file size is quite big (500MB) it is up to you to copy a file without any hot-channel, provided that you write somewhere that you have performed the test.
Pulser procedures with DRM
This paragraph explains how you have to proceed in case you want to perform a pulser test with DRM as VME controller.
The pulser procedure is operated from 2 different PCs: tofbaby for the baby side and tofback for the back side.
The PCs have to be connected to the crates through optical fibers: use LINK 0 to connect to crate Right and LINK 1 to crate Left.
Before to start turn on alle the VME boards and check if the communication between the PC and the crate is still working (for example using /SOFT/TEST/scancrate -c [link nr.] )
The software system that performs data-aquisition activities is DATE. You can launch it by the comand:
daqControl
Another usefull comand is
infoBrowser
which allows to monitor the DATE log messages.
Now you can set the run configuration with
editDb
this windows should appear:
In the Equipment menu' it is possible to manage the run settings. In the LDCs column select tofbaby_LDC (or tofback_LDC ). In the 2 LTM equipments the FEAs threshold can be set to the right value.
Then, go to the TRG-0 item if you want to change the trigger settings. To pulse the different modules you have to set to 1 the various pulser section. For example, set pulserSection0 to 1 if you want to pulse the external module, then pulserSection1 for the intermediate one and pulserSection2 for the central one.
Only the right crate house a CPDM. If we want a trigger signal synchronous with the pulse signal, the trigger coming from the DRM in the right crate has to be send to the left crate as well. In order to do that, a special cable with RJ45 (ethernet) connector on both side has to be connected to the CTRL input of both DRM. Then set the enableLeftCrate to 1.
With the TRM equipment it is possible to enable/disable a TRM and to set the channel mask.
The monitoring program is MOOD. You run you have just to type
mood
You can follow the instruction from the old wiki page
LTM
Mounting instructions
Put LTM into crate slot 2. Connect the clk cable from CPDM (if the CPDM is not mounted yet, skip this step. The LTM has its
own clk).
Label the grey FEAC-LTM cable: number 8 is the longer, number 1 the shortest. You have to pass these cable under the signal cable
and then up on the SM structure corner. Then insert them on the metallic support.
You will find in R-010 office the KEL patch cords (gold colour). These are already labelled with a number 1-4 and 5-8. THESE PATCH CORDS ARE VERY FRAGILE: PLEASE HANDLE THEM GENTLY AND REMOVE THEM BEFORE TAKING ANY RELEVANT ACTION ON THE CRATE ( REMOVING TRM, ...). Please pay attention to put the right on the proper LTM connector ( labelled 0-3 and 4-7).
After mounting them write a short file called SMx_y_z.dat (where x=SM number, y=A,C side , z=left,right) containing the
length of the 8 cable and put it on wiki.
How to make a Temperature run
cd /home/tofcosm/VME/LTM/LTM
./myadc2 5
The program is now filling a file called "byandrea.dat". When you want to stop make CTRL C. You may find in the same directory a kumac file called ttt.kumac. Run it under paw.
How to change threshold
Threshold adjust
To change the FEA thresholds edit the file /home/toftest/sm/configurationFiles/SOR.commands (on pctofsm is in directory /home/toftest/sm/pctofsm/.).
