2 GENERAL DESCRIPTION

STIM300 is an IMU consisting of 3 high accuracy

MEMS-based gyros, 3 high stability accelerometers

and 3 high stability inclinometers in a miniature

package. Each axis is factory-calibrated for bias,

sensitivity and compensated for temperature effects

to provide high-accuracy measurements in the

temperature range -40°C to +85°C. The unit runs off

a single +5V supply.

can be defined when ordering or set by customer.

When STIM300 is powered up, it will perform an

internal system check and synchronise the sensor

channels. As an acknowledgement of the complete

power-up sequence, it will provide special datagrams

containing part number, serial number and

configuration data. STIM300 will then automatically

proceed to provide measurement data. Connect power

and STIM300 will provide accurate measurements over the RS422 interface.

The measurement data is transmitted as packages of data on a fixed format (datagram) at intervals given by the

intermediately or permanently changed by overwriting the current settings in the flash memory. In Service Mode the

commands and responses are in a human readable format (ASCII); to enable the use of terminal-type software during

typical product integration. Service Mode also provides the ability to perform single measurements, perform

diagnostics and obtain a higher detail level of detected errors reported in the status bytes.
