Functional Description

Flexibilty

The following functions are available in many configurations giving the user the ability to specify exactly what’s needed. Interrupts are individually or globally enabled or disabled via software. A status register is provided to determine the interrupt source.

Analog Inputs

The Analog Inputs feature software programmable gain with ranges of 0-5V, 0-10V, ±5V, and ±10V. The configuration employs an instrumentation pre-amplifier per channel which allows for differential inputs, 200V Common Mode Rejection, high input impedance, and optional factory channel by channel pre-settable gain (1-200) to accommodate low-level inputs from sensors. Inputs 4-20mA are available as a factory-installable option.

Analog Outputs

Output ranges of 0-5V, 0-10V, ±5V and ±10V, are field selectable with jumpers. Note that four conversions may take place at once and that, since the D/As are double buffered, data for the next conversion may be loaded simultaneously.

Counter Timers

The circuit uses an 82C54 (3 sixteen bit counter/timers). The user has access to each counter/timer’s gate, clock, and output signals. The output of counter two can be used to generate an interrupt. The software package supports counting events, frequency output, pulse and frequency measurement.

Digital I/O

The circuit uses an 82C55A PPI with mode 0 supported. Ports A and B (16 lines) are buffered and pulled up to 5V. Port C features Change of State detection.

Software

TThe package includes a graphical Windows setup program detailing all jumper settings. Also included are drivers, samples and utilities for DOS, Windows operating systems (Windows 95, 98, Me, NT4, 2000, XP, and 2003), and Linux. Full register-level support for use in custom real-time or embedded operating systems.
