To connect the RedLab 1008 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 1008. - Page 12 If the LED turns off If the status LED is illuminated but then turns off, the computer has lost communication with the RedLab 1008. To restore communication, disconnect the USB cable from the computer, and then reconnect it. This should...

Port B0-B7 Port C0-C7 47 kilohm (kΩ) pull-up resistor and is configured as an input by default. If needed, the RedLab 1008 can be factory configured to provide pull-down resistors. Caution! Port A0 through Port C7 have no overvoltage/short circuit protection. Do not exceed the voltage limits or you may damage the pin or the RedLab 1008. -

RedLab 1008 and possibly the computer. Screw terminal wiring The RedLab 1008 has two rows of screw terminals. Each row has 15 connections. Pin numbers are identified in Figure 5. The pins are labeled for eight-channel single-ended mode operations. - Page 17 RedLab 1008 User's Guide Functional Details Screw terminal pins 16-30 The screw terminals on the right edge of the RedLab 1008 (pins 16 to 30) provide the following connections: Four digital I/O connections ( DIO0 DIO3 Two analog output connections (...

In single-ended mode, the input signal is referenced to signal ground (GND). The input signal is delivered through two wires: The wire carrying the signal to be measured connects to CH# IN.
- Page 20 RedLab 1008 User's Guide Functional Details The maximum differential voltage on any given analog input pair must remain within the selected voltage range. The input [common-mode voltage + signal] of the differential channel must be in the −10 V to +20 V range in order to yield a useful result.

Page 21: Digital I/O Terminals (Dio0 - Dio3)
RedLab 1008 User's Guide Functional Details Since the analog inputs are restricted to a −10 V to +20 V signal swing with respect to ground, all ranges except ±20 V can realize a linear output for any differential signal with zero common mode voltage and full scale signal inputs. -
Page 22: Power Terminals
Bus-powered hubs and notebook computers may limit the available output current to 100 mA. Just connecting the RedLab 1008 to your computer draws 20 mA of current from the USB +5V supply. Once you start running applications with the device, each DIO bit can draw up to 2.5 mA, and each analog output can draw 30 mA. -
Page 23: Counter Terminal
The primary error sources in the RedLab 1008 are offset and gain. Nonlinearity is small in the RedLab 1008, and is not significant as an error source with respect to offset and gain. Figure 11 shows an ideal, error-free, RedLab 1008 transfer function. The typical calibrated accuracy of the RedLab 1008 is range-dependent, as explained in the "Specifications"... - Page 24 Figure 13. ADC Transfer function with gain error For example, the RedLab 1008 exhibits a typical calibrated gain error of ±0.2% on all ranges. For the ±10 V range, this would yield 10V × ±0.002 = ±20 mV. This means that at full scale, neglecting the effect of offset for the moment, the measurement would be within 20 mV of the actual value.
