6.1 Communication Modules Introduction
DB9 in the rear panel of the DC load IT8511+/IT8511A+/IT8511B+/IT8512+
/IT8512A+/IT8512B+/IT8512C+/IT8512H+/IT8513A+/IT8513C+ is TTL level,
which can be connected to the serial port of the PC through the level
conversion of the accessory.
The communication module is IT-E121/IT-E121A/IT-E122/IT-E123.
The IT8513B+/IT8514B+/IT8514C+/IT8516C+ comes standard with RS232
and USB communication interfaces.
Please do not connect the standard RS232 cable to the
IT8511+/IT8511A+/IT8511B+/IT8512+/IT8512A+/IT8512B+/IT8512C
+/IT8512H+/IT8513A+/IT8513C+ electronic load, which may
damage the instrument.
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 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 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.
