Used but in excellent working condition. AT-MIO-16D Multifunction I/O Board for the PC AT. Stored and shipped in anti-static packaging. Guaranteed not DOA.

The AT-MIO-16D combines the functionality of two popular National Instruments boards, the AT-MIO-16 and the PC-DIO-24. The AT-MIO-16D contains two logical sections–the MIO-16 circuitry and the DIO-24 circuitry. Henceforth, we will refer to the entire board as the AT-MIO-16D, and to a particular logical part of the board as either the MIO-16 or DIO-24 circuitry. The MIO-16 circuitry contains a 12-bit ADC with up to 16 analog inputs, two 12-bit DACs with voltage outputs, eight lines of transistor-transistor logic (TTL) compatible digital I/O, and three 16-bit counter/timer channels for timing I/O. The DIO-24 circuitry is a 24-bit parallel, digital I/O interface based on an 82C55A programmable peripheral interface (PPI).

The MIO-16 circuitry of the AT-MIO-16D is a high-performance multifunction analog, digital, and timing I/O circuit for the PC. The AT-MIO-16D has a fast 12-bit ADC, 16 single-ended or eight differential channels (expandable with SCXI and the AMUX-64T), and programmable gains of 1, 10, 100, and 500 or 1, 2, 4, and 8. The AT-MIO-16D has a 9-µsec converter, guaranteed transfer rates of up to 100 ksamples/sec, and a 512-word A/D FIFO buffer to obtain the highest possible data acquisition rate. The AT-MIO-16D has internal or external A/D timing, two double-buffered multiplying 12-bit DACs, unipolar or bipolar voltage output, and an onboard DAC reference voltage of 10 V. The AT-MIO-16D also has onboard timers for waveform generation, eight digital I/O lines that can sink up to 24 mA of current, and three independent 16-bit counter/timers for frequency counting, event counting, and pulse output applications. The AT-MIO-16D has timer-generated interrupts, a high-performance RTSI bus interface with four triggers for system-level timing, and full PC AT I/O channel DMA capability.

The DIO-24 circuitry of the AT-MIO-16D is a 24-bit parallel, digital I/O interface for the PC. An 82C55A PPI controls the 24 bits of digital I/O. The 82C55A is very flexible and powerful when interfacing with peripheral equipment, can operate in either a unidirectional or bidirectional mode, and can generate interrupt request outputs. You can program the 82C55A for almost any 8-bit or 16-bit digital I/O application. The 100-pin connector of the AT-MIO- 16D breaks out into two standard 50-pin female connectors via a cable assembly. The pin assignments for these connectors are compatible with standard 24-channel digital I/O applications.
