Installing the USB-1808X-OEM

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 USB-1808X-OEM product page on our website for information about the software supported by

the USB-1808X-OEM.

Install the software before you install your device

The driver needed to run the USB-1808X-OEM is installed with the software. Therefore, you need to install the

software package you plan to use before you install the hardware.

Installing the hardware

To connect the USB-1808X-OEM 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

Status

LED on the USB-1808X-OEM turns on

after the device is successfully installed.

If the Status 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.

Updating firmware

Your DAQ device contains firmware that can be updated in the field if required. Firmware is available for

download at

www.mccdaq.com/firmware.aspx

. MCC recommends that you check this page periodically to see

if an update to your device firmware is available.
