Main processes
 

The following process has to be started from hb-cr09 machine under hbshift username and ~/sa_ECALPT/  directory:
 

1.  pte_moni    : This is the pretrigger INITIALIZATION process.  It loads fed LUTs pretrigger LUTs and starts the pretrigger monitor process pt_moni under hb-vme42 machine.

Troubleshooting

Sometimes in case of troubles a reset of the system is needed:
 
 

• login on hb-vme47
• cd pro/can
• h_fan2.exe
• return
• off pt1
• yes
• return
• off pt1
• yes
• return
• off fed1
• yes
• return
• off fed2
• yes
• return
• off fed3
• yes
• return
• off fed4
• yes
• return
• off fed5
• yes
• return
• off fed6
• yes
• return
• on pt1
• yes
• return
• on fed1
• yes
• return
• on fed2
• yes
• return
• on fed3
• yes
• return
• on fed4
• yes
• return
• on fed5
• yes
• return
• on fed6
• yes
• return
• reset pt1
• yes
• return
• quit

On hbshift from hb-cr09 machine:

• cd sa_ECALPT
• pte_moni

How to Install pretrigger boards
 
 In this section a manual for MIDDLE ECAL pretrigger boards installation will be given.
The STATIC TESTS can be performed at any moment without interfering with any DAQ activity.
The DINAMIC TESTS need NO DAQ ACTIVITY (please contact shift crew and ask for such a condition).
 

STATIC TESTS

• Take one pretrigger board and check jumper and VME address configuration. A checklist of jumper configuration will be added soon to this document. Anyway the pretrigger boards are delivered already configured for installation
• Switch the PRETRIGGER 7 crate OFF
• Insert the board in slot 5 on PRETRIGGER 7 crate (the one with hb-vme43 CPU)
• Connect the downmost lemo connector on the board frontpanel with the lemo cable coming from the crate backplane. This cable is necessary to feed a fast clock signal (40 MHz) to the transmission card.
• Do not insert the patch panel cables on the board input connector
• Switch the PRETRIGGER 7 crate ON
• Check that the uppermost red LED on the board frontpanel is first ON and than OFF. This indicates the normal succesfull completion of the FPGA loading
• On the hb-vme43 CPU login as hb-ecal and go into the pro/pt directory
• Start the pt program giving the most significant byte (2 digits) of the board VME address
• Execute the T test from the main menu in the long version (10 min). No error have to be detected during the test
• Execute the L test from the main menu in the long version (10 min). No error have to be detected during the test
• Execute again the T test from the main menu in the short version . No error have to be detected during the test
• execute the F test from the main menu. No error have to be detected during the test
