Attaching Modules to the Computer

This section describes how to attach a DT9837 Series module to the host computer.
Note: Most computers have several USB ports that allow direct connection to USB devices.
If your application requires more DT9837 Series modules than you have USB ports for, you
can expand the number of USB devices attached to a single USB port by using expansion
hubs. For more information, refer to
You can unplug a module, then plug it in again, if you wish, without causing damage. This
process is called hot-swapping. Your application may take a few seconds to recognize a
module once it is plugged back in.
The DT9837 Series modules use less than 500 mA; therefore, they do not require an external
power supply.
You must install the device driver for your module before connecting the module(s) to the
host computer. Run the installation program on your Data Acquisition OMNI CD to install the
device driver and other software for the module.

Connecting Directly to the USB Ports

To connect a DT983 Series module directly to a USB port on your computer, do the following:
1. Attach one end of the USB cable to the USB port on the module.
2. Attach the other end of the USB cable to one of the USB ports on the host computer, as
shown in
The operating system automatically detects the USB module and starts the Found New Hardware
wizard.
