We now have a drasi DAQ running for our (p,g) experiments.
The RIO we have it installed right now is: r4l-58
It shall be used with the user <litv-exp>

The DAQ-controle shall be done from lxg1275 inside a SCREEN SESSION named "daq"
tab 0 >> drasi 
tab 1 >> logger
tab 2 >> rate
tab 3 >> stream server
tab 4 >> file writing (optional)

To check and control running daq:

login on lxg1275
> ssh litv-exp@lxg1275

enter screen session
> screen -x daq

DRASI
go to tab 0
> ctrl-a 0 
should be quite, no errors showing, no terminal outputs
full restart proceedure
> ssh r4l-58
> cd esrdaq_2018/r4l-58
> ./start.sh (for det. triggered daq)
> ./pulser.sh (for internal pulser trigger)
> ctrl-c (for killing daq)

LOGGER
go to tab 1
> ctrl-a 1
should be quite, no errors showing, no terminal outputs
full restart proceedure
> ssh r4l-58
> cd esrdaq_2018/r4l-58
> ./logger.sh

RATE MONITOR
go to tab 2
> ctrl-a 2
rates should update each second
"incr" should be event rate per sec 
"send" column should be reasonable value if data is written
full restart proceedure
> ssh r4l-58
> cd esrdaq_2018/r4l-58
> ./rate.sh

EMPTY STREAM SERVER
go to tab 3
> ctrl-a 3 
empty stream should be running  
number of processed events should keep increasing
you should see the number of clients connected
full restart proceedure (on lxg1275)
> empty stream://r4l-58 --server=stream:6002
