Table 3. NI 5624R IF Digitizer Front Panel Connectors
Label Connector Type Function
IF IN SMA connector Analog input terminal for intermediate frequency (IF) signals.
PFI 0 SMA connector Programmable function digital I/O (DIO) connector for triggers or events.
CLK IN SMA connector Input for an external ADC Clock (Sample Clock) or Reference Clock to the digitizer.
CLK OUT SMA connector Output for an ADC Clock (Sample Clock) or PLL Reference Clock from the digitizer.
DIGITAL I/O HDMI™ connector DIO terminal that contains 12 general-purpose DIO signals. DIO lines are direction configurable as input or output.
Caution The DIGITAL I/O connector accepts a standard, third-party HDMI cable, but the DIGITAL I/O port is not an HDMI interface. Do not connect the DIGITAL I/O port on the NI 5624R to the HDMI port of another device. NI is not liable for any damage resulting from such signal connections.

The following table provides information about the module front panel LEDs and the device states they indicate.

LED Indication
ACCESS Indicates the basic hardware status of the NI 5624R module.
  • OFF—The module is not yet functional, or the module has detected a problem with a PXI Express power rail.
  • AMBER—The module is being accessed. Accessed means that the device setup registers are being written to in order to control the device.
  • GREEN—The module is ready to be programmed.
ACTIVE Indicates the NI 5624R module state.
  • OFF—User has not turned on LED.
  • AMBER—User defined.
  • GREEN—User defined.
  • RED—The module has detected a PLL unlock or an error state, such as a clock fault, a power shutdown condition, or a thermal shutdown condition. The behavior of this LED can also be user-defined.
