Documentation 

In addition to this hardware user's guide, you should also receive the 

OMB-DAQ-2400, OM-USB, OM-WEB, 

and OM-WLS Series Data Acquisition Software User's Guide

. This booklet provides an overview of the 

software you received with the device, and includes information about installing the software. 

Optional accessories 

 

OM-ACC-102 — Two-position screw terminal connector blocks (quantity ten). 

 

OM-ACC-160 — Backshell for use with the OM-ACC-102 two-position screw terminal connector blocks.

Unpacking 

As with any electronic device, 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. 

If any components are missing or damaged, notify Omega Engineering immediately by phone, fax, or e-mail.

Installing the software 

Refer to the 

Software User's Guide

 for instructions on installing

 

the software. This booklet ships with the 

hardware, and is available in PDF at 

http://www.omega.com/manuals/manualpdf/M4803.pdf

Installing the hardware 

Install the software before you install your device 

The driver needed to run the OM-USB-2404-60 is installed when you install the software. Therefore, you need 
to install the software you plan to use before you install the hardware. 

To connect the OM-USB-2404-60 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 OM-USB-2404-60 blinks steadily 
to indicate that the device is initialized and receiving power.
