11.2 - Communication Port on Front Face Panel 

 

This port is used for communication through the Front Face Panel between a local Lap-top PC. 
 
The physical link is RS232 by the standard female 9-pin D-sub connector available on the Front Face Panel.  
Via this Port complete Relay management and data acquisition is possible.
