hard disk.
You may load a previously saved fi le by us-

ing the “File,” “Open” command and select-

ing the desired confi guration fi le. If you are 

connected to the unit, the parameters will 

be automatically uploaded.
(See also: System Restore From Personality 

Module, Section 10.4.)
Please  take  the  time  to  familiarize  your-

self with the laptop interface controls and 

screens. Next establish communication with 

the JSD-80 using a standard RS232 cable. Se-

lect the “Connect” icon on the toolbar and, if 

everything is as it should be, the computer 

will connect with the JSD-80.

When you fi rst accessed the JSD software, 

the small window in the lower right hand 

corner  of  the  main  window  looked  like 

this:

Once you connect to the JSD, the computer 

will  download  all  the  data  stored  on  the 

JSD-80  to  the  laptop’s  memory.  This  data 

can  consist  of  Preamp  Parameters,  EQ 

Parameters,  Front  Panel  Parameters  and 

Profi le  Information.  Once  that  action  has 

taken place, the small window will change 

to this:

You are now ready to set up the JSD-80.
If you are setting up the JSD-80 for the fi rst 

time, you may want to fi ll in the particulars 

of the venue in the “Theatre Information” 

boxes  provided  in  the  Profile  tab.  They 

may  be  fi lled  in  and  edited  like  a  normal 

text fi le.
The  “Component  Information”  boxes  are 

fi lled in at the factory and are not editable 

by the end user.

Note:  As  stated  previously,  this  infor-

mation is not functional insofar as the 

functional

functional

operation of the processor is concerned, 

but can aid you greatly in future endeav-

ors.

At  any  time  during  the  Profile  entry  or 

setup  procedures,  the  information  from 

those tasks may be saved to the laptop’s 

hard drive or other convenient data storage 

medium by utilizing the “Save” function and 

providing a path and fi le name.
After  completion  of  the  alignment  proce-

dure (see Section 8), the complete system 

confi guration may be saved to the laptop’s 

hard drive or other data storage medium by 

utilizing the “Save” function and providing 

a path and fi le name.
