RS-232C
The RS-232C connector is used to control the instrument from a computer 
through RS-232C connection, using the appropriate software. The RS-232C 
interface can be used for controlling the module with PCs running non-Agilent 
Control Software. Most (but not all) of the Control Software products of other 
manufacturers communicate via this RS-232C interface. If in such a scenario 
the RS-232C interface cannot be used, the analog output connector can be 
used instead, in which case an additional handheld controller (connected via 
the CAN Connector) must be used.
The RS-232C connector can be configured with the configuration switch 
module next to the GPIB connector. The RS-232C is designed as DCE (data 
communication equipment) with a 9-pin male SUB-D type connector. The pins 
are defined as:
