I added two words for each board before their ARS data :
So we can tell from which board the data is coming from and monitor the event counters in the FIFO.
The itimeout is the time taken to get the FIFO not full.
We closed the box with screws and put the calorimeter at the running position. The position is secured with a C-clamp. Everything seems to fit (tightly), and all channels are operational (checked at the end of the cable tray).
We should be able to take cosmics, but for LED we should open the box and put the board in.
