NI USB-622x/625x/628x OEM User Guide
Attaching External LEDs
USB-622x/625x/628x OEM devices have two LEDs that reflect the device
state. The green READY LED indicates when the device is powered on and
configured as a USB device. The yellow ACTIVE LED indicates USB bus
activity.
Three connectors on the device allow you to connect an external LED
circuit to the device, as shown in Figure 10. To connect an external READY
LED, use E1 as the positive connection (+3.3 V) and E2 as the negative
connection. To connect an external ACTIVE LED, use E1 as the positive
connection and E3 as the negative connection. E1 is current limited with
a 100 Ω resistor to the 3.3 V internal supply. This configuration limits
the current to approximately 16 mA into a single external LED or
approximately 8 mA each when both LEDs are lit. You also can limit this
current further by using external resistors, also shown in Figure 10.

Pin 1, VDC In, is connected to VDC through the fuse (reference designator
XF1). The VDC is the voltage provided by the power supply through the
power connector (reference designator J4/J6/J81) and must be 11–30 VDC,
20 W.
Pin 2, VDC Out, provides power to the circuitry on the device. When the
switch is in the On position, the VDC power supply from pin 1 is routed to
pin 2.
Pin 3, 100 kΩ to Ground, connects pin 2 to ground through a 100 kΩ
resistor when the switch is in the Off position.

Replacing Fuses
USB-622x/625x/628x OEM devices have a replaceable T 2A 250V
(5 × 20 mm) fuse that protects the device from overcurrent through the
power connector.
(USB-628x Devices Only) USB-628x OEM devices also have a replaceable
F 2A 125V fuse that protects the device from overcurrent through the +5 V
terminal(s).
Replacement fuse information can be found in Table 1. To replace a broken
fuse in USB-622x/625x/628x OEM devices, complete the following steps.
1.
Power down and unplug the device.
2.
Replace the broken fuse while referring to Figure 13 for the fuse
locations.

Modifying the USB Device Name in Microsoft Windows
You can change how the USB-622x/625x/628x OEM device name appears
when users install the device in both the Found New Hardware Wizard that
appears when the device is initially installed and in the Windows Device
Manager.
Windows Vista/XP Users
Figure 14 depicts how a USB-6251 OEM device name appears in the
Found New Hardware Wizard and Windows Device Manager.
Figure 14. USB-6251 OEM Device in the Found New Hardware Wizard and
Device Manager (Windows Vista/XP)
To modify the device name in the Found New Hardware Wizard and
Windows Device Manager in Microsoft Windows Vista/XP, complete the
following steps.
Note
You must have NI-DAQmx 8.7 or later installed on your PC.
1.

Locate the OEMx.inf file in the y:\WINDOWS\inf\ directory,
where x is the random number assigned to the INF file by Windows,
and y:\ is the root directory where Windows is installed.
17
NI USB-622x/625x/628x OEM User Guide
Note New security updates to Microsoft Vista and NI-DAQ 8.6 or later create random INF
files for NI hardware. Windows assigns random file numbers to all INF files, which causes
the user to search through several INF files until the correct file is located.
If you want to revert back, save a copy of this file as
OEMx_original.inf in a different location.
2.
Edit the device INF file by opening OEMx.inf with a text editor.
At the bottom of this file are the descriptors where Windows looks to
identify the device. Locate the two lines of text that contain in quotes
the descriptors for the device name you are modifying. Change the
descriptor on both lines to the new device name, as shown in Figure 15.

3.
Save and close the INF file.
4.
Go to the Windows Device Manager.
(Windows Vista) In the Device Manager, notice that the OEM device
now appears as My Device, as shown in Figure 16.
(Windows XP) In the Device Manager, right-click the OEM device under
Data Acquisition Devices, and select Uninstall. Power down the OEM
device and disconnect the USB cable from your PC.
