USB PORT

Figure 3-1. OM-DAQ-USB-2401 Hardware and Dimensions

NOTE:

The external power port is used in applications which have USB hubs that are not self-powered. See the next section for more information.

NOTE:

The 'STATUS LED' blinking at Scan Rate means an acquisition is in progress. At a fast scan rate, the 'STATUS LED' appears solid. The 'POWER LED' in solid means the unit has power

3.2 USB Hubs and Power Adaptors

With the use of USB hubs you can connect up to 10 DAQ units to one PC. USB hubs can be of the self-powered type, or of the USB-powered type. Both types of hubs are available from a variety of vendors.
