3、Hardware Installation
FY-AHRS-2000B should be installed on a stable platform; the installation of the surface
should be parallel with the ground as far as possible when still placed on the platform, and keep
it away from the magnetic field effects as far as possible. Magnetic objects must avoid being
included. For example: car engines, electric motors, audio speakers, steel, iron and steel nuts or
bolts. We recommend using copper, plastic or aluminum as the FY-AHRS-2000B installation and
packaging materials. Because it equipped with a gyro and acceleration sensor, so we must fix it
on the platform cautiously.
When install FY-AHRS-2000B, make ensure that the "forward" on the shell (it means the
positive X-axis) keep the same direction with the platform move forward straight. This is very
important. Once the installation is finished, you’d better make ensure that no more change in use.
Since magnetic interference may exist in the surroundings, for realize the correction of
course, we advised that please run the magnetic field compensate program of the
FY-AHRS-2000B after each time the environment changed .We must select the install position
carefully when install the FY-AHRS-2000B.The selected position should expose the electronic
component fully to the Earth's magnetic field, while keep it relatively isolated from the magnetic
field effects and interference.
FY-AHRS-2000B includes gyroscopes and accelerometers, in order to initialize the sensors,
you should keep it horizontal and static for about 3 to 5 seconds when Power-on. If you
power-on it during movement, it may cause the attitude data accuracy decline.
If the external environment changed so much, when boot and maintain the stationary state,
the gyroscope angular rate is greater than 1 ° per second, please perform "configuration" - ""
gyro to initialize ".
4、 Power and Signal Connections
FY-AHRS-2000B connects to the user equipment through standard TTL serial protocol, so
if you are using a notebook computer, please prepare a USB-serial converter. FY-AHRS-2000B
factory default serial port baud rate is 19200, the output data refresh rate is 20Hz.
Recommended operating voltage is 5V DC power input. The voltage input range is 3.3V ~
6V, if the supply voltage is out of the range, the AHRS will be damaged or caused performance
reduction.
5、Demo Software Installation and Use
The demo software program's document of FY-AHRS-2000B is AHRS test software.exe,
after completing the installation, the interface is as follows:
