Chapter 1
Introducing the RedLab 1208FS
This user's guide contains all of the information you need to connect the RedLab 1208FS to your computer and to the signals you want to measure.
The RedLab 1208FS is a USB 2.0 full-speed device supported under popular Microsoft 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 RedLab 1208FS features eight analog inputs, two 12-bit analog outputs, 16 digital I/O connections, and one 32-bit external event counter. The RedLab 1208FS is powered by the +5 volt USB supply from your computer. No external power is required.
The analog inputs are software configurable for either eight 11-bit single-ended inputs, or four 12-bit differential inputs. Sixteen digital I/O lines are independently selectable as input or output in two 8-bit ports.
A 32-bit counter can count TTL pulses. The counter increments when the TTL levels transition from low to high (rising-edge).
A SYNC (synchronization) input / output line lets you pace the analog input acquisition of one USB module from the clock output of another.
The RedLab 1208FS is shown in Figure 1. I/O connections are made to the screw terminals located along each side of the RedLab 1208FS.

RedLab 1208FS User's Guide Introducing the RedLab 1208FS
Connecting a RedLab 1208FS to your computer is easy
Installing a data acquisition device has never been easier.
The RedLab 1208FS 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 1208FS. No third-party device driver is required.
The RedLab 1208FS is plug-and-play. There are no jumpers to position, DIP switches to set, or interrupts
to configure.
You can connect the RedLab 1208FS 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.

RedLab 1208FS User's Guide Installing the RedLab 1208FS
Unpacking the RedLab 1208FS
As with any electronic device, you should take care while handling to avoid damage from static electricity. Before removing the RedLab 1208FS 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 RedLab 1208FS is damaged, notify Meilhaus Electronic immediately by phone, fax, or e-mail. For international customers, contact your local distributor where you purchased the RedLab 1208FS:

Installing the software
Refer to the Quick Start Guide for instructions on installing the software Guide (available on our RedLab CD (root directory)).
Installing the hardware
Be sure you are using the latest system software
Before you install your RedLab 1208FS, run Windows Update to update your operating system with the latest HID and USB drivers.
To connect the RedLab 1208FS to your system, turn your computer on, and connect the USB cable to a USB port on your computer or to an external USB hub that is connected to your computer. The USB cable provides power and communication to the RedLab 1208FS.
When you connect the RedLab 1208FS for the first time, a series of (Windows XP) or dialogs (other Windows versions) opens as the RedLab 1208FS is detected by your computer.
Found New Hardware popup balloons
It is normal for multiple dialogs to open when you connect the RedLab 1208FS for the first time. For additional information, refer to the "Notes on installing and using the RedLab 1208FS" that was shipped with the RedLab 1208FS.
The last popup balloon or dialog states "Your new hardware is installed and ready to use," and the LED on the RedLab 1208FS should flash and then remain lit. This indicates that communication is established between the RedLab 1208FS and your computer.
