LEDs
USB-6221/6229/6251/6259 OEM devices have two LEDs that reflect
the device state. The green READY LED indicates whether the device is
powered on and configured as a USB device. The yellow ACTIVE LED
indicates whether there is USB bus activity.
Three connectors on the device allow you to connect an external LED
circuit to the device. 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 on. You also can limit this current further by using external
resistors as shown in Figure 8.

Pin 1 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) and must be 11–30 V, 20 W.
Pin 2 provides power to the circuitry on the USB-6221/6229/6251/6259
OEM device. When the switch is in the On position, the VDC power supply
from pin 1 is routed to pin 2.
Pin 3 connects pin 2 to ground through a 100 kΩ resistor when the switch
is in the Off position. This allows the internal power supply in the
USB-6221/6229/6251/6259 OEM device to safely discharge to ground
when it is powered off. Figure 11 shows a schematic of the switch.

Chassis Ground
Chassis ground provides a connection between the enclosure and USB
ground.
D GND is connected to the chassis ground through an internal connection
to hole A, shown in Figure 12. The chassis ground directly connects to USB
shield ground.
The USB-6221/6229/6251/6259 OEM device includes several mounting
holes that are plated and designed for user-configured ground connections
between the device chassis ground and the appropriate system ground.
Figure 12 shows where the different grounds are connected.
Note The holes that are labeled B are reserved for an external shield. Do not use these
holes as mounting holes.
