Chapter 4 Remote Operation Mode
The DB9 interface connector on the rear panel of the power supply can be transferred to RS-232
interface, the following information will tell you how to use the computer to control the output of the
power supply.
4.1 IT-E131 Communication cable
The DB9 interface connector on the rear panel of power supply is TTL voltage level; you can use
the communication cable (IT-E131) to connect the DB9 interface connector of the power supply
and the RS-232 interface connector of computer for the communication.

Note: It will not work if you connect the DB9 interface connector of the power
supply to the RS232 interface connector of computer directly by a standard
RS232 cable. Please use IT-E131 to connect them.
4.2 Communication setting
Before using the remote operation mode, please make sure that the baud rate and communication
address in power supply are the same as in the computer software, otherwise, the communication will
fail, you can change the baud rate and communication address from the front panel or from computer.
1 . Address: the range is from 0 to 254 , default setting is 0
2 . Baud rate: 4800,9600,19200 and 38400 are selectable, default setting is 4800
3 . Data bit : 8 bit
4 . Stop bit : 1
5 . Parity : None
PARITY = NONE
