Chapter 1
Introducing the RedLab 1024HLS
This user's guide contains all of the information you need to connect the RedLab 1024HLS to your computer
and to the signals you want to measure.
The RedLab 1024HLS is a USB 2.0 low-speed module supported under popular Microsoft
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.
Refer to the "Be sure you are using the latest system software" note in Chapter 2, "Installing the RedLab
1024HLS," to make sure you are using the latest USB drivers.
The RedLab 1024HLS is a high drive, 24-line digital I/O module that includes one 32-bit external event
counter. The module is powered by the +5 volt USB supply from your computer. No external power is required.
An emulation of the 82C55 in mode 0 (only) sets the direction of the 24 digital I/O lines in four ports. Each
digital port can be configured for either input or output. The 74FCT244 outputs are high-drive TTL, capable of
sourcing 15 mA and sinking 64 mA.
The RedLab 1024HLS is shown in Figure 1. All I/O connections are made to the screw terminals on each side
of the RedLab 1024HLS.
