automation device to your computer and to other data acquisition hardware.

The USB-DIO24/37 is a USB 1.1 low-speed module supported under popular Microsoft

Windows

operating

systems. It is designed for USB 1.1 ports, and was tested for full compatibility with both USB 1.1 and USB 2.0

ports.

The USB-1024LS features 24 bits of digital I/O and one 32-bit external event counter. The device is powered

by the +5 volt USB supply. No external power is required.

An on-board industry standard 82C55 programmable peripheral interface chip provides the 24 discrete digital

I/O lines in four ports. You can configure each digital port independently for either input or output.

The USB-1024LS USB device is shown in Figure 1-1. All I/O connections are made to the screw terminals
