Login to adaqsc as aslow
ssh -X adaqsc -l aslow
password same as "adaq" (similar to "adev" but replace 12gev by 12daq)
Then "cd slowc" and pwd /adaqfs/home/aslow/slowc [aslow@adaqsc slowc]$ ./hvs LEFT
You might need to turn on the crate if it's not already on.
For reasons not entirely clear, sometimes the server does not work. One symptom is that the "hvs" GUI will not initialize. Another symptom is that the GUI may be already running but you cannot change any HV values. This server runs on rpi8. The awkward but certain way to recover is
login to rpi8
ssh -X rpi8 -l pi
I can't say the pw here, but its the same as on other rpi's.
(call Bob M. if you need this pw)
sudo reboot
After a few minutes, log in again and
./scripts/start_hv_cron
It will print a lot of stuff. Leave it.
Then on adaq1 as aslow, do the start procedure mentioned above.
cd slowc
./hvs LEFT
