Description
The NB-DIO-24 Digital I/O Board, manufactured by National Instruments, is a key component of the NB Series designed for use with the Macintosh NuBus. This board is allocated 2.0 A of power per slot, with 1.0 A available for accessories, and it consumes 0.8 A itself. It features 24 digital I/O lines, divided across three ports, each with eight lines. Handshaking circuitry is incorporated for each port to facilitate reliable data transfer.
Operation of the NB-DIO-24 is managed by NI-DAQ driver software, ensuring compatibility with a variety of accessories including the SC-206X Series, SC-2051 Cable Adapter Board, CB-50 Connector Block, ER-8/16 Relay Accessory, AT-DIO-32F Digital I/O Board, and the NB1 Ribbon Cable. However, when connected to an SCXI module in Multiplexed mode, certain lines (PB0 to PB3, PA0) are reserved exclusively for SCXI use, and the board does not support configurations involving multiple chassis.
