DB9 in the rear panel of the DC load could connect with RS-232 through on TTL connector. The
following description may help you to know how to control the output of the DC load through PC.
WARNING: Don't connect the DC load's DB9 connector to a standard RS232 instrument; doing
so may damage the instrument.

5.1Communication Modules Intruduction

IT-E121 Communication Module
The DB9 interface connector on the rear panel of the DC load is TTL voltage
level; you can use the communication module IT-E121 and an a standard
RS232 extension cable to connect the DB9 interface connector of the DC load
and the RS-232 interface connector of computer for the communication.
IT-E121A Communication Module
The DB9 interface connector on the rear panel of the DC load is TTL voltage
level; you can use the communication module IT-E121A and an a standard
RS232 extension cable to connect the DB9 interface connector of the DC load
and the RS-232 interface connector of computer for the communication.
IT-E121A is derived on the basis of IT-E121,the main difference between them
is that the DB9 interface connector of the RS232 changes from female to
male ,so that can be directly connected to the standard LAN interface.
IT-E122 Communication Module
The DB9 interface connector on the rear panel of the DC load is TTL voltage
level;
IT-E121A communication cable
