AKRON, OH, December 12, 1997 — DATAQ Instruments Inc., announces today the availability of the newest addition to its data acquisition product family, the Model DI-222 Portable Data Acquisition System. The 16-channel single-ended/8-channel differential analog input system, with expansion to 256 analog inputs, features 12-bit resolution with inputs up to ±10V and four gains from 1 to 1000. Previous DI-200 Series portable data acquisition systems were limited to inputs of ±5V. The DI-222 is equipped with one analog output, eight digital inputs and eight digital outputs. The system is available in two versions: one that supports portable battery powered PC field applications and one that supports desktop PC applications.

The DI-222 provides both data acquisition and digital signal processing using a 16-million instruction per second (MIPS) digital signal processor (DSP) that provides the added bonus of programmability. The DI-222 uses two scan lists to allow analog input, analog output, digital input and digital output each at different rates, and all at the same time, providing solutions for complex stimulus/response and synchronization problems.

The DI-222 connects to the parallel port of any computer. Signal connections can be made to the system's 5-way binding posts or via the side-mounted DAS-16 compatible connector.

The Model DI-222 is equipped with the following features:

The DI-222 is supported by the following software:
