Here is a link to a detailed technical note: http://files.microstrain.com/Orientation%20Conversion%20formulas.pdf

No – only one can be used at a time.  The device auto-senses which communication signal is attached (USB or serial), and only uses that channel for communications.

The 3DM-GX3® -25 USB and RS-232 communication interfaces are built to satisfy the standard USB-IF and EIA specifications.  MicroStrain provides 6 foot cables as standard.  Many techniques can be used to extend the length of the communication interfaces including powered USB hubs, USB boosters, RS-232 extenders, etc.

The 3DM-GX3® -25 is calibrated at the factory and requires no further calibration by the user.  The user may wish to ‘tare’ or ‘zero’ the axes once the device is mounted in place and this should be done as a function of the user’s application.

Yes. Any number of units can be operated by a host at the same time. Several considerations surround this implementation and we suggest that you discuss your requirements with MicroStrain sales or a support engineer.

Yes, there are no limitations.  However, if a user requires a ‘zeroing’ of the axes, this must be done in the user’s external application.  Good practice dictates that the orientation matrix be used to calculate such zeroing.

Yes. The sampling rates are adjustable.  You may set the sampling rate from 1 to 1000 Hz.

The following orientation outputs formats are available:

• Acceleration and Angular Rate
• DeltaAngle and DeltaVelocity
• Magnetometer Vector
• Acceleration, Angular Rate and Magnetometer Vector
• DeltaAngle, DeltaVelocity and Magnetometer Vector
• Orientation Matrix
• Euler Angles
• ...and more.

A detailed description of these outputs can be found in the Data Quantities Available section of the Data Communications Protocol manual.

Yes. We provide a complete data communications protocol manual which describes in detail each and every command and response that is available with the device.  Applications may be developed in any programming environment (C, VB, LabVIEW, Matlab, etc.) which supports communication via serial port.

When you initially purchase a 3DM-GX3® -25, a starter kit (SK) provides you with everything you need to get started! SKs include a 3DM-GX3® -25 module, communication and power cables, software and manuals.  In subsequent purchases you may only require additional modules or other individual components. Several interfaces are available creating several starter kit variations.

*All SKs include software and manuals.

** The prototype adapter cable does not require power when plugged into USB but does require power if wired into user’s circuit.
