5. Remote Operation
5.1 Overview
The 62000D Series DC power supply can be controlled remotely via USB, GPIB or Ethernet.
The USB interface supports USB 2.0/USB 1.1. GPIB interface is an 8-bit parallel data bus
that synchronizes with the host bus commands. Ethernet interface is used in local area
network for data transmission.
5.1.1 USB Interface
(1) Hardware Support: USB 2.0 and USB 1.1
(2) Software Support: USBTMC class and USB488 subclass
(3) OS Support: Windows 98/2000/XP/Vista/Windows 7/Windows 8
(4) Installing Driver: 62000D Series USB Interface supports USBTMC, so if the PC
OS supports USBTMC (installed NI-VISA runtime version 3.00
or above) it is no need to install other drivers. The OS will
search for the standard USBTMC driver installation program
automatically.
If the PC’s operating system does not support USBTMC, it is suggested to install the NI-VISA
runtime version 3.00 or above first. When the installation of NI-VISA runtime is done, the
USBTMC driver program is stored in the operating system. The PC can communicate with
62000D Series via NI-VISA after using the USB.

5.1.3 Ethernet Remote Control
To remote program a 62000D DC power supply via a PC with Ethernet interface, the 62000B
needs to confirm the IP address, Gateway address and Subnet mask in advance. To ensure
reliable data transmission, TCP is used for data transmission and the communication port is
5025.
