use this to check state of the pgp link, and the readout group, size and link mask (instead of kcuStatus): kcuSim -s -d /dev/datadev_0
use this to configure readout group, size, link mask: kcuSimValid -d /dev/datadev_0 -c 1 -C 2,320,0xf
- I think this hangs because it's trying to validate a number of events (specified with the -c argument?)

The timing system should come back up. If not, use a machine with afs (psdev01, pslab03?)
source /afs/slac/g/reseng/IPMC/env.csh
fru_deactivate shm-tst-lab2-atca01
fru_deactivate shm-tst-lab2-atca02
fru_deactivate shm-tst-lab2-atca03
fru_activate shm-tst-lab2-atca01
fru_activate shm-tst-lab2-atca02
fru_activate shm-tst-lab2-atca03
Then have to restart the base processes? (pyxpm...)
