Configure Remote Control Interface
USB Interface
The USB device port on the rear panel is used for remote control.
The USB port can be configured as either a TMC or CDC interface.
When configured as a TMC interface, the DMM can be controlled
using National Instruments NI-Visa software*. NI-Visa version 3.0
and above supports USB TMC.
When configured to CDC, the USB port on the DMM will appear as
a virtual COM port to a connected PC. Any terminal program that
can communicate via a serial port can be used for remote control.
Before the DMM can be used for remote control using the CDC or
TMC USB class, install the appropriate CDC or TMC USB driver
included on the User Manual CD.
Note
*To use the TMC interface National
Instruments Measurement and Automation
Explorer can be used. This program is available
on the NI website,
., via a search
for the VISA Run-time Engine page, or
“downloads” at the following URL,
