Helios includes a complete autocalibrating jumper-less analog and digital I/O circuit similar to our top-of-the-line PC/104 analog I/O board. It contains 16 analog inputs with 16-bit resolution and 250KHz sample rate, backed by a 2048 sample FIFO with programmable threshold. Programmable input ranges from a wide-range +/-10V down to 0-1.25V are provided. The analog circuitry also includes 4 D/A channels with 12-bit resolution and jumperless output range selection and simultaneous update capability. On the digital side, Helios provides 40 digital I/O lines with programmable direction, as well as two counter/timers for A/D sample rate control, pulse counting, frequency generation, or other applications. Its advanced control logic has more features and flexibility to fit almost any application, such as internal/external A/D clock source, scan and single-sample modes, and our exclusive programmable FIFO threshold that lets you tune the board's performance to your application. The data acquisition circuit is fully supported by our Universal Driver software for a wide range of operating systems.
