SXR servers are in R06. There’s likely space in there.

Our, or at least my understanding was that we can use an trigger output from any nearby host with an EVR. To be specific:
- PLC: B940-009-R07
- EVR: B940-009-R06 (whatever host we have running the exit slit camera)
I assumed the point/beauty of the EVRs is to distribute these trigger sources so it doesn’t have to originate from any specific node. We were going to include a counter in the payload so we could address any off-by-one issues. I guess it’s more complicated!
Sorry, Chris, I didn’t realize this thread had taken up residence elsewhere otherwise I would have responded sooner. I try to keep an eye on the pcds-it list but it’s kind of a blindspot for me.
The question I have at this point is, where does the Ethernet/<whatever medium we end up choosing> have to go to deliver the UDP packet?
MHz Conversation with Georgi and Zach (Brief Update)
May 4, 2022
- the absolute encoder stayswill continue to be used
- perhaps add a second high-rate (maybe even MHz?) relative encoder
- in november either we have to increase the current absolute encoder rate, or do the "interpolation". beam starts at a few kHz.
- feels like a good chance we need interpolation mode since the MHz encoder does not yet exist
- existing absolute encoder may trigger at 500Hz or 1kHz, but no more
- existing absolute encoder has estimates for velocity, acceleration, jerk, maybe more? zach can include these in the data stream fairly easily so we can see how well it does
