Connecting to USB
You can use the USB connector on the USB-6001/6002/6003 OEM device to connect to the
USB host. In this case, leave the D+ and D- signals and VBUS (on the 34-pin connector)
unconnected.
You can also use a USB connector on your motherboard to connect the USB-6001/6002/
6003 OEM device to the USB host through the 34-pin connector. In this case, do not connect to
the USB connector on the USB-6001/6002/6003 OEM device.
Using the Status LED Driver
The LED signal indicates the device status as listed in the
NI USB-6001/6002/6003 User Guide
. An open collector output drives the LED signal. For
applications that use the LED signal, connect an external pull-up resistor from the LED signal
to an external voltage.
