STIM202

Description

STIM202 is a cluster of 1, 2 or 3 ultra high accuracy gyros in a miniature package with a RS422 interface. The cluster function is based on an integrated 32-bit microcontroller that provides flexibility in the configuration. Electronically calibrated axis alignment is standard. Any combination of axes can be provided.

Performance

Each axis is factory-calibrated for bias, sensitivity and compensated for temperature effects to provide high-accuracy measurements. The unit runs off a single +5V supply and communicates via a "plug & play" high-level RS422 interface. The use of a 32-bit RISC ARM microcontroller provides flexibility in the configuration, like choice of output unit, sampling frequency, LP filter -3dB frequency and RS422 bit-rate and protocol parameters.

For more advanced users, STIM202 may be put in Service Mode. In this mode all the configuration parameters can be intermediately or permanently changed by overwriting the current settings in the flash memory. Service Mode also provides the ability to perform single measurements, perform diagnostics and obtain a higher detail in the status byte.
