USB-6259/6289 OEM Connector Pinout © National Instruments Corporation 11 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. OEM (On-Board) 3.3 V E3 E3 E2 E1 100 Ω E2 E1 External External READY ACTIVE LED LED Figure 10.

Figure 11 shows the pins on the power switch and circuitry. 100 kΩ to Ground VDC Out VDC In 3 2 SW1 Switch NC NC 1 XF1 J4/J6/J8 100 kΩ Outer Shell SW1 Power to Device 2 1 3 XF1 FUSE J4/J6/J8 Power Connector 100 kΩ Figure 11. Schematic for the Power Switch 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. 1 The power connector is designated as J4 on USB-6225/6255 OEM devices, J6 on USB-6221/6229 OEM devices, and J8 on USB-6251/6259/6281/6289 OEM devices. © National Instruments Corporation 13 NI USB-622x/625x/628x OEM User Guide Connecting the USB-622x/625x/628x OEM Device to Your Chassis The USB-622x/625x/628x OEM device includes several plated mounting holes that are designed for customer grounded connections, as shown in Figure 12.

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. © National Instruments Corporation 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. Original File Modified File Figure 15. INF File Descriptors Changed to “My Device” (Windows Vista/XP) 3. 4. Save and close the INF file. 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.
