Instructions for the Backup 2D Event Display
Certain very rare events can make it impossible to launch the 2D and 3D
event displays normally used in the SLD Data Assembly Room.
These include loss of IP address name service and loss of the entire network
connection to SCS.
The 3D event display cannot survive these conditions since it relies
heavily on SCS central resources (RAVEL is a centrally managed Unix machine).
The 2D event display can be run without any SCS resources by following the
recipe below.
-
SET HOST or TELNET to SLDACQ any way that you can.
-
Logon as user: SGI
-
Password:
-
Issue the command: @RSH_2DRAWDSP
The usual display of raw data from the event multiplexor pool
will appear on the SLDU7 workstation.
Alternate displays are also available, and you can have more than one
displaying on different windows on SLDU7 at the same time.
-
To see a display of cosmics rather than raw data events:
@RSH_2DCOSMIC
-
To see a raw data display of the latest Z event found by EPEM
(an option normally viewed from the 3D Display):
@RSH_2DRAWEPEM
-
To see a recon data display of the latest Z event found by EPEM
(an option normally viewed from the 3D Display):
@RSH_2DRECEPEM
