INTERFACE : RS232  
 
The test units of the XS series are equipped with a RS232C interface operating in talker and listener 
modes.  This  option  makes  possible  the  integration  of  any  unit  of  the  series  in  an  automatic 
measurement or test system in manufacturing or incoming inspection department. 
 
A 9 pins connector is provided on the rear panel for the interface connection. The RS232C standard 
defines electrical specifications for the transmission of serial information. The use of the RS232C port 
requires five lines: 
 
  Receive data            (RXD) 
  Transmit data         (TXD) 
  Data terminal ready    (DTR) 
  Data set ready       (DSR) 
  Signal ground            (GND) 
 
This interface also requires a cable type CO179. Refer below for the cable wiring 
 
 
 
 
The communication parameters cannot be changed and are : 
 
  Parity  : no 
  Format : 8 bits 
  Stop bit : 1 
 
To modify the communication speed, go to the CONFIG menu, on the INTERFACE line and select 
RS232, press on the RIGHT arrow, then with the UP/DOWN arrows, set the communication speed
