Software features

For information on the features of InstaCal and the other software included with your USB-ERB08, refer to the

Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at

www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf

Check www.mccdaq.com/download.htm

for the latest software version or versions of the software supported

under less commonly used operating systems.

Connecting a USB-ERB08 to your computer is easy

Installing a data acquisition device has never been easier.

 The USB-ERB08 relies upon the Microsoft Human Interface Device (HID) class drivers. The HID class

drivers ship with every copy of Windows that is designed to work with USB ports. We use the Microsoft

HID because it is a standard, and its performance delivers full control and maximizes data transfer rates for

your USB-ERB08. No third-party device driver is required.

 You can connect the USB-ERB08 before or after you install the software, and without powering down your

computer first. When you connect an HID to your system, your computer automatically detects it and

configures the necessary software. You can connect multiple HID peripherals to your system using a USB

hub.

 You can connect your system to various devices using a standard four-wire cable. The USB connector

replaces the serial and parallel port connectors with one standardized plug and port combination.

 Data can flow two ways between a computer and peripheral over USB connections.
