Step 1Step 1
• 4 DIALOG on the same branch (same ELMB), 1 SB (out crate)• 4 DIALOG on the same branch, 1 SB (in crate)• 4 DIALOG in 2 different branches
Cables of very different lengths (from few cm to 15 m)
• Tested using programmable patterns on DIALOG Unused inputs may cause noise on outputs …
Test program accessing DIALOG via KVASER and SB

Step 2Step 2
• TB and IB• 4 DIALOG 8 outputs each (32 channels to IB)
• OR2 on DIALOG• OR4 on IB (M2R3 style – “worm” order!) channels 0,1 … 7 • 8 outputs from IB (3 out of seen on the scope)
ORs (pulses on different DIALOG outputs are delayed by 25 ns one with respect to the other)
Time Re-aligned ORs(by DIALOG)
Time Re-aligned and shaped ORs(by DIALOG)

NoteNote
The “OR-ing”scheme in the IB is not trivial …
By the way:Do you know that DIALOG can make OR ONLY starting from corresponding CARIOCA channels ??
0 – 01 – 1 2 – 2 …7 – 7
(see 1st DIALOG note, since 2001, and further releases …)
We hope you know …

Step 3Step 3
• ODE (and its TB) inserted (7 SYNC-plugged on)• 8 IB outputs were given to the ODE
• The inputs were moved among different ODE (SYNC) inputs and the relevant channel histograms (inside SYNC) read back directly by the internal ELMB

Step 4Step 4
• The OptRx board is inserted in the chain
• Data written on the L0 derandomizer (random trigger) are read by the ODE controller and sent to the OptRx via the optical link
• Data are read from the OptRx interface and visualized (correctly) on the PC screen
• A few combinations were tested

Conclusions and PlansConclusions and Plans
• The chain test went reasonably well
• All the prototypes and the all the one-to-one modules’ connections were already deeply tested so:
• Time was spent more to cure minor “linking” setup problems than debugging conceptually the system
• Further steps: test of the L0 trigger transmission (we need a simple trigger emulator or a better PG) test the ODE in its full equipped setup (24 SYNC on the board) Load the crates with a higher number of boards to test if problems on the back-plane arise Insert the FE boards on the chain or even a complete chamber (without gas at the beginning) test the L0 trigger receiver (Marseille) test with chamber and cosmic rays
This tests have to be concluded by next June
• We need a safe (and large enough) place to install “permanently” the chain. • The larger efforts are in setting-up all the connections every time we start a new test. • The installed chain have to be constantly available to add and test new pieces of the system.• The possibility of a remote connection would be opportune.• Cannot LNF find a better logistic solution (in short time) ?• Should we look for another place ?
