Introduction
The USB-4700 series consists of true plug & play data acquisition devices. No more opening up your computer chassis to install boards; just plug in the module, then get the data. It’s
easy to use and efficient. USB-4751/4751L is a 48/24-bit digital I/O module with USB interface. Its 48/24 bits are divided into six/three 8-bit I/O ports and users can configure each
port as input or output via software. USB-4751/USB-4751L also provides one event counter and three 16-bit timers, which can be cascaded to become a 32-bit timer.
