Chapter 1

Introducing the miniLAB 1008

This user's guide contains all of the information you need to connect the miniLAB 1008 to your computer and
to the signals you want to measure.

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

2.0 ports.

The miniLAB 1008 features eight 12-bit analog input signal connections and 28 digital I/O connections. It is
powered by the +5 volt USB supply. No external power is required.

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 miniLAB 1008 USB device is shown in Figure 1-1.

miniLAB 1008 User's Guide Introducing the miniLAB 1008

Connecting a miniLAB 1008 to your computer is easy

Installing a data acquisition device has never been easier.

! The miniLAB 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 miniLAB 1008. No third-party device driver is required.

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

configure.

! You can connect the miniLAB 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.

Please read this booklet completely before installing any software or hardware.

). This booklet supplies a brief description of

Unpacking the miniLAB 1008

As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the miniLAB 1008 from its packaging, ground yourself using a wrist strap or by
simply touching the computer chassis or other grounded object to eliminate any stored static charge.

If your miniLAB 1008 is damaged, notify Measurement Computing Corporation immediately by phone, fax, or
e-mail. For international customers, contact your local distributor where you purchased the miniLAB 1008.
