You can attach a DT9820 Series module to the host computer in one of
two ways:
• Connect directly to a USB port of the host computer, described on
. Use this method if one or two DT9820 Series function
modules are sufficient for your application.
• Connect to one or more self-powered USB hubs, described on
. Use this method if your application requires more than
two DT9820 Series function modules connected to the host
computer.
Note:
DT9820 Series modules are low-power devices (using less
than 500 mA); therefore, they do not require external power
supplies.
Also, the DT9820 Series modules are automatically calibrated when
you power the module. No calibration steps are required.
