To connect the RedLab 1608FS 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 1608FS. - Page 12 If the LED turns off If the LED is lit but then turns off, the computer has lost communication with the RedLab 1608FS. To restore communication, disconnect the USB cable from the computer, and then reconnect it. This should restore...

Burst scan mode In burst scan mode, you can acquire data with the RedLab 1608FS using the full capacity of its 32 K sample FIFO. The acquired data is then read from the FIFO and transferred to a user buffer in your computer. You can initiate a single acquisition sequence of one, two, four, or eight channels by either a software command or an external hardware trigger. -

V. No external power supply is required. The LED on the front of the RedLab 1608FS indicates the communication status. It uses up to 5 mA of current and cannot be disabled. The table below explains the function of the RedLab 1608FS LED. -
Page 15: Screw Terminal Wiring
Functional Details Screw terminal wiring The RedLab 1608FS has two rows of screw terminals—one row on the top edge of the housing, and one row on the bottom edge. Each row has 20 connections. Pin numbers are identified in Figure 4. -

Page 17: Digital I/O Terminals (Dio0 To Dio7)
When you configure the digital bits for input, you can use the RedLab 1608FS digital I/O terminals to detect the state of any TTL-level input. Refer to the switch circuit shown in Figure 6 and the schematic shown in Figure 7. -
Page 18: Power Terminals
The RedLab 1608FS alone draws 150 mA of current from the USB +5 V supply. Once you start running applications with the RedLab 1608FS, each DIO bit can draw up to 2.5 mA. The maximum amount of +5 V current available for experimental use, over and above that required by the RedLab 1608FS, is the difference between the total current requirement of the RedLab 1608FS (based on the application), and the allowed current draw of the computer platform (500 mA for desktop computers and self-powered hubs). -
Page 19: Calibration Terminal
Functional Details Calibration terminal connection (pin 17) is an output you should use only to calibrate the RedLab 1608FS. Refer to the pinout diagram on page 3-16 for the location of this pin. Calibration of the RedLab 1608FS is software- controlled by InstaCal. - Page 20 The RedLab 1608FS offset error is measured at mid-scale. Ideally, a zero volt input should produce an output code of 32768. Any deviation from this is an offset error. Figure 9 shows the RedLab 1608FS transfer function with an offset error. The typical offset error specification for the RedLab 1608FS on the ±10 V range is ±1.66 mV.
- Page 21 Combining these two error sources in Figure 11, we have a plot of the error band of the RedLab 1608FS at ±full scale (±10 V). This plot is a graphical version of the typical accuracy specification of the product.

Page 22: Gain Queue
This feature creates a gain list which is written to local memory on the RedLab 1608FS. The gain list is made up of a channel number and range setting. An example of an eight-element list is shown in the table below. -
Page 23: Synchronizing Multiple Units
You set the function of the SYNC pin (pin 36) for pacer input or pacer output by using InstaCal. By default, the SYNC pin is set for pacer input. To synchronize a master RedLab 1608FS with a slave RedLab 1608FS and acquire data from 16 channels, follow the steps below: 1. -
