Chapter 1

Introducing the RedLab 1008

This user's guide contains all of the information you need to connect the RedLab 1008 to your computer and to

the signals you want to measure.

The RedLab 1008 is a USB 1.1 low-speed analog and digital I/O device that is supported under popular

Microsoft®Windows®operating systems. The RedLab 1008 is fully compatible with both USB 1.1 and USB

2.0 ports.

The RedLab 1008 features eight 12-bit analog input signal connections and 28 digital I/O connections. It is

Two screw terminals rows provide connections for eight analog inputs, two 10-bit analog outputs, four

bidirectional digital I/O lines, and one 32-bit external event counter. You can configure the analog input

connections with software as either four single-ended or eight differential channels. All analog connections

terminate at the screw terminals.

24 bidirectional digital I/O lines are also available on a 37-pin connector.

An on-board industry standard 82C55 programmable peripheral interface chip provides 24 digital I/O lines that

terminate at a 37-pin connector.

The RedLab 1008 USB device is shown in Figure 1.

RedLab 1008 User's Guide Introducing the RedLab 1008

Connecting a RedLab 1008 to your computer is easy

Installing a data acquisition device has never been easier.

The RedLab 1008 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 RedLab 1008. No third-party device driver is required.

The RedLab 1008 is plug-and-play. There are no jumpers to position, DIP switches to set, or interrupts to

configure.

You can connect the RedLab 1008 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 and power 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.

You do not need a separate power supply module. The USB automatically delivers the electrical power

required by each peripheral connected to your system.

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