Issues with optical readout of multiple 1x2 RD53B modules together.
Hi Experts.
We were trying to read back two CROC 1x2 modules powered serially here at Rice, But calibrations are running only for one of them. The module that works seems to depend on the position the optical link is declared.
The two files RH0007_RH0015.xml and RH0015_RH0007.xml are different only by position of OpticalGroup, which come next to each other, just swapped. All lanes are deteted but scans only give result for one of the modules. I have attached the corresponding output of pixelalive in output_RH0007_RH0015.txt and output_RH0015_RH0007.txt
RH0007 is connected to J4 and RH0015 to J2 at the portcard. Eventually we are trying to run 5 1x2 modules from a poertcard simultaneously. I can add pictured of the setup if needed.
Best, Aman
