hi Tonko,
Almost. Your channel counts are correct as far as I know (Except you meant 36864 = 288*128.) However, the APV's will be organized as 8 per group instead of 12 per group, owing to the detector/frontend configuration. So there will be 36 groups, which will be read out with 6 crate segments (6 ARC) and 3 ARM per crate segment with 2 cable groups per ARM (as usual). 6 ARC, 18 ARM in total.
For sure I hope to test the readout during the summer, and we should coordinate on that. September sounds fine to me.

Hello,

I'm iterating through the readout/DAQ requirements for FST.
From previous discussions this is what I have:

1) 3 ARM/ARC crates
2) 2 ARCs per crate (total 6)
3) 2 ARMs per ARC (or 4 per crate, 12 in total)
4) 36854 channels all-in-all

Are these number still correct??

Perhaps in September I will try to power-up the relevant
ARC/ARM crates in STAR as well as the DAQ PCs and
see if we can take data with the above geometry.

Thoughts?
