RS232 Remote Control Function Check 
 
Invoke a terminal application such as Realterm. 
For RS232, set the COM port, baud rate, stop bit, 
data bit and parity accordingly. 
To check the COM settings in Windows, see the 
Device Manager. For example, in Win7 go to the  
Control panel ā System ā Hardware tab. 
If you are not familiar with using a terminal 
application to send/receive remote commands from 
the serial port, please see page 189 for more 
information. 
Run this query command via the terminal after 
the instrument has been configured for  
RS232 remote control (page 186).
