Digital Remote Control

To meet the varying needs of todays engineers, a comprehensive array of interfaces is provided. RS-232, USB, GPIB and LAN (Ethernet) with LXI support are provided as standard.

Each of the digital bus interfaces provides full control of voltage, current, and output on/off, plus read-back of voltage, current and status.  The interfaces are opto-isolated from the output.

Command Set and IVI Driver

The basic command set for the CPX Series is compatible with both the PL-P series and the QL-P series.

An IVI driver for Windows is supplied. This provides support for common applications such as LabView*, LabWindows* and HP-VEE*.


An RS-232/RS-423 interface is provided for use with legacy systems. This type of serial interface remains in common useage and is perfectly satisfactory for the control of power supplies because data speed is not an issue.


USB provides a simple and convenient means of connection to a PC and is particularly appropriate for small system use.

A USB driver is provided suitable for Windows* systems.


The GPIB interface conforms with IEEE-488.1 and IEEE-488.2.

GPIB remains the most widely used interface in larger system applications.

LAN-Ethernet with LXI

The LAN interface uses a standard 10/100 base-T Ethernet hardware connection with ICMP and TCP/IP Protocol for connection to a Local Area Network or direct connection to a single PC.

This interface supports LXI and is the most appropriate for larger system use because of its scalable nature.

LXI Compliance

The LAN interface is compliant with LXI-C. LXI is the next-generation, LAN-based modular architecture standard for automated test systems managed by the LXI Consortium, and is expected to become the successor to GPIB in many systems.
