Chapter 1
Introducing the RedLab 3103
Overview: RedLab 3103 features
This user's guide contains all of the information you need to connect the RedLab 3103 to your computer and to
the signals you want to control. The RedLab 3103 is part of the Measurement Computing brand of USB-based
data acquisition products.
®
The RedLab 3103 is a USB 2.0 full-speed device that is supported under popular Microsoft
operating systems. The RedLab 3103 is fully compatible with both USB 1.1 and USB 2.0 ports.
The RedLab 3103 provides eight channels of analog voltage output, eight digital I/O connections, and one
32-bit event counter.
The RedLab 3103 has two quad (4-channel) 16-bit digital-to-analog converters (DAC). You set the voltage
output range of each DAC channel independently with software for either bipolar or unipolar. The bipolar
range is ±10 V, and the unipolar range is 0 to 10 V. The analog outputs may be updated individually or
simultaneously. A bidirectional synchronization connection allows you to simultaneously update the DAC
outputs on multiple devices.
Windows®
The RedLab 3103 features eight bidirectional digital I/O connections. You can configure the DIO lines as
input or output in one 8-bit port. All digital pins are floating by default. A screw terminal connection is
provided for pull-up (+5 V) or pull-down (0 volts) configuration.
The 32-bit counter can count TTL pulses.
The RedLab 3103 is powered by the +5 volt USB supply from your computer. No external power is required.
All I/O connections are made to the screw terminals located along each side of the RedLab 3103.
