Introducing the RedLab 1208LS
This user's guide contains all of the information you need to connect the RedLab 1208LS to your computer and
to the signals you want to measure.
The RedLab 1208LS is a USB 1.1 low-speed device 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 RedLab 1208LS features eight analog inputs, two 10-bit analog outputs, 16 digital I/O connections, and one
32-bit external event counter. The RedLab 1208LS is powered by the +5 volt USB supply from your computer.
No external power is required.
The RedLab 1208LS analog inputs are software configurable for either eight 11-bit single-ended inputs, or four
12-bit differential inputs. An on-board industry standard 82C55 programmable peripheral interface chip
provides the 16 digital I/O lines in two 8-bit ports. You can configure each digital port independently for either
input or output.
The RedLab 1208LS is shown in Figure 1. I/O connections are made to the screw terminals located along each
side of the RedLab 1208LS.
