Chapter 1

Introducing the USB-1608FS-Plus

The USB-1608FS-Plus is an analog input and digital I/O data acquisition device providing the following
features:

 Eight 16-bit single-ended (SE) analog input channels

Each input channel has a dedicated A/D converter for simultaneous sampling.
Software-selectable analog input ranges of ±10 V, ±5 V, ±2 V, and ±1 V

 Eight individually configurable digital I/O channels
 One 32-bit event counter
 One external digital trigger input
 Bidirectional external clock for synchronous operation with more than one device.
 Screw terminals for field wiring connections

The device is powered by the +5V USB supply from the computer, requiring no external power.
The USB-1608FS-Plus is compatible with both USB 1.1 and USB 2.0 ports. The speed of the device may be

limited when using a USB 1.1 port due to the difference in transfer rates on the USB 1.1 versions of the
protocol (low-speed and full-speed).

Unpacking

As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the device from its packaging, ground yourself using a wrist strap or by simply
touching the computer chassis or other grounded object to eliminate any stored static charge.

Contact us immediately if any components are missing or damaged.

Installing the software

Refer to the MCC DAQ Quick Start for instructions on installing the software on the MCC DAQ CD. Refer to
the device product page on the Measurement Computing website for information about the included and
optional software supported by the USB-1608FS-Plus.

Install the software before you install your device

The driver needed to run the USB-1608FS-Plus is installed with the software. Therefore, you need to install the
software package you plan to use before you install the hardware.

For operation on a Windows operating system, we recommend that you run Windows Update to update your
operating system with the latest USB drivers.

Installing the hardware

To connect the USB-1608FS-Plus to your system, connect the USB cable to an available USB port on the
computer or to an external USB hub connected to the computer. Connect the other end of the USB cable to the
USB connector on the device. No external power is required.

When connected for the first time, a Found New Hardware dialog opens when the operating system detects the
device. When the dialog closes, the installation is complete. The LED on the USB-1608FS-Plus turns on after
the device is successfully installed.

If the LED turns off

If communication is lost between the device and the computer, the device LED turns off. To restore
communication, disconnect the USB cable from the computer and then reconnect it. This should restore
communication, and the LED should turn on.

Calibrating the hardware

The Measurement Computing Manufacturing Test department performs the initial factory calibration. Return
the device to Measurement Computing Corporation when calibration is required. The recommended calibration
interval is one year.

The USB-1608FS-Plus does not support field calibration.
