Introduction 5
USB-2405
1.4.5 Digital I/O
1.5 Software Support
ADLINK provides comprehensive software drivers and packages
to suit various user approaches to system building. In addition to
programming libraries, such as DLLs, for most Windows-based
systems, ADLINK also provides drivers for application environ-
ments such as LabVIEW® and MATLAB®. ADLINK also provide
ActiveXcomponent ware for measurement and SCADA/HMI, and
breakthrough proprietary software. All software options are
included in the ADLINK All-in-One CD.
Be sure to install the driver & utility before using the USB-2405
module.
