4. Communication Introduction
FTP3000 series power supply provides users with standard RS232, LAN, optional CAN communication interfaces.
Users can operate the power supply remotely using a PC connected to the power supply with proper wire. The
communication configuration data is stored in power supply internal memory, power off or power down does not
affect its configuration. Once there is modification in communication configurations, must restart the power
supply for changes to take effect.
4.1 Communication Interface
4.1.1 RS232
FTP3000 series uses a default baud rate of 9600bps, parity is none, does not support flow control method.
Regarding RS232 interface, only TxD and RxD PIN can transmit data, its PIN are explained as following:

4.1.2 LAN
The FTP3000 series power supply has an Ethernet communication interface and adopts UDP communication
mode. The default IP address is 192.168.1.123, the default subnet mask is 255.255.255.0, and the default port
number is 7000.
----------------------------------------------------------------------------------------------------------------------
Before starting communication, make sure that the address of the PC and the power supply are
in the same network segment, and that there is no duplicate IP address with the power supply
in this network segment, otherwise it will not be able to connect correctly.
