Subject: MesyTec Shaper Control 
The MesyTec Shaper & Constant Fraction (MSCF) is used to process the PMT/det signals for the ADC in the second DAQ.
It can be setup on its front panel, but single channel setup is very tedious.
Remote control of the settings is possible using an epics server and client.

All of the following is done with the "litv-exp" user:

server: atpnuc001 (in the screen session "E142")
client: lxg1275 

The server should run undisturbed, but in case of a power failure, you can start the server like this:
> ssh litv-exp@atpnuc001
> cd e142
> ./E142_start_ioc.sh

To check server:
> ssh litv-exp@atpnuc001
> screen -x (CTRL-a CTRL-d to leave screen)

To connect the client gui for remote control, do:
> ssh litv-exp@lxg1275
> E142_epics
The panel is more or less self-explaining. 
One thing has to be noted: the Monitor Channel selection is shifted by -1.
I.e., [ch 1] is button [0], etc.

The MSCF settings can be stored and loaded to/from file by using a bash-script.
The settings will be saved/loaded from: 
/u/litv-exp/e142/mscf_settings/
files names are "setting_e142.<linux_timestamp>"

The scripts are also in /u/litv-exp/e142/mscf_settings/
use 
./mscf_save.sh                   for saving the current settings to a new file
use 
./mscf_load_last.sh              to load the last settings file (by timestamp in the filename) 
use 
./mscf_load_file.sh <filename>   to load the settings of a specific file
