The 120-Channel Digital Input / Output (DIO) Board offers a number of I/O types of data on a single 3U VPX board. The DIO Board provides TTL input and output channels, LVDS input and output channels, RS-422/485 channels, and digital input and output channels. The DIO Board provides RS-422/485 to RS-232 conversion as well as differential SPI channels. All I/O signals are routed to either the VPX backplane or a 160-pin Front Panel connector. The DIO Board also offers a configurable clock and onboard user-controlled LEDs. A user-programmable Xilinx Artix -7 Field-Programmable Gate Array (FPGA) is used to provide access to the digital data over the PCIe interface. The FPGA is programmed automatically on power-up through a configuration PROM.
