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.

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.
