This chapter provides the following information to remotely control the AT5220 via the RS-232C 
or USB interface.

About SCPI 

AT5220 can use the RS-232 interface to communicate with the computer to complete all the 
instrument functions.   

8.1

 

  RS-232C 

RS-232 is currently widely used serial communications standard, is also called asynchronous 
serial communications standard, it is applied to realize communication of PC and PC

、

  PC and 

peripheral. RS is the English abbreviation for 

“

Recommended Standard

”

  (recommended 

standard), 232 is standard number, this standard is officially announced by EIA in 1969. 
 
Most configuration of serial port is not based on RS-232 standard: each port use 25-core or 9- 
core connector (now all PC use 9-core connector). The most common RS-232 signal is as 
below:

RS232C Connection 

RS-232 serial interface can be connected to serial interface of controller (such as PC or PLC ) 
by DB-9 cable. 

 

Tip: instrument cannot use null modem cable. 
Users can make it or buy 9-core cable from Applent Instruments. 
If users make 3-core cable, should pay attention to:   
If using PC’s built-in DB9 port, probably users need to short circuit 4-6
