Attaching Modules to the Computer
You can attach a DT9824 module to the host computer in one of two ways:
• Connect directly to a USB port of the host computer, described on page 24 . Use this
method if one or two DT9824 modules are sufficient for your application.
• Connect to one or more self-powered USB hubs, described on page 25 . Use this method if
your application requires more than two DT9824 modules connected to the host
computer.
You must install the device driver before connecting your DT9824 module(s) to the host
computer.
Note: The DT9824 module is a low-power device (using less than 500 mA); therefore, it does
not require an external power supply.
Connecting Directly to the Host Computer
Generally, host computers have two or more USB ports. These ports are completely
independent. To connect a DT9824 module directly to a USB port of the computer, do the
following:
1. Attach one end of the EP365 cable, which is shipped with the DT9824 module, to the USB
port on the module.
2. Attach the other end of the EP365 cable to one of the USB ports on the host computer, as
shown in
Figure 3 .
The operating system automatically detects the USB device and starts the Found New Hardware
wizard.
