Loss of communication with LeCroy1445A.

It often happens when LeCroy was turned off, or loses its power due to power dip.
Indications are:
- "bbchv" app on sc3 shows black on/off
- "bbchv" app doesn't update readout voltages/current
- Cannot turn on/off from "bbchv"
Solution is:
Go to SC5 computer. There should be "Restore LeCroy Communication" window:
   
LeCroyRestart

Follow the instructions on the window.
If the window is not on SC5 - open a terminal and type ./scripts/restartLC.py
Make sure you have bermuda terminal open in the next monitor 
(If not, open terminal, type "sys@bermuda" command. Password is the same as one in shift leader's binder for SC5 sysuser)
