MAUI Oscilloscopes Remote Control and Automation Manual
Connecting With VXI-11
LXI is an industry-standard specification for LAN-based instruments that utilizes the VXI-11 protocol for
TCP/IP communications and instrument discovery. For information, visit www.lxistandard.org.
Teledyne LeCroy oscilloscopes are LXI Class-C compliant. We have implemented a full-featured stack that
allows any command or query to be sent using the VXI-11 protocol, beyond the LXI requirements for
discovery and execution of simple *IDN? queries.
Note: You can use the VXI-11 protocol for remote control of Teledyne LeCroy oscilloscopes even if
your network is not LXI compliant. For those who cannot utilize ActiveX or are programming in
newer languages such as C#, LXI (VXI-11) is the best remote control setting.
Resources
The LXI specification stipulates that vendors supply:
l An IVI driver for the instrument.
Note: Some newer versions of NI-VISA install with IVI drivers. The LeCroyScope IVI driver is
required to connect to MATLAB applications using LXI (VXI-11). See Resources.
l A web server to simplify remote control configuration. To access this page from the controlling PC,
enter the oscilloscope IP address in URL field of a browser.
Controller Setup
Open port 111 on the controller for TCP/IP communications.
Install NI-VISA to manage the interface functions of the underlying TCP/IP connection.
If you are running Windows and can utilize ActiveX controls, we highly recommend installing ActiveDSO on
the controller to simplify communications with the oscilloscope.
Optionally, install the LeCroyScope IVI driver or LabVIEW driver.
Oscilloscope Setup
Go to Utilities > Utilities Setup > Remote and choose LXI (VXI-11).
We recommend that you modify the password for LAN access. The default username is lxi.lecroyuser and
password is lxi. You can reset to these defaults by pressing LAN Configuration Reset.
Record the instrument's IP address for use in VISA resource strings and function calls.
