1、Hardware Installation
FY-AHRS-1200A 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-1200A 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-1200A, 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-1200A after each time the
environment changed .We must select the install position carefully when install the FY-AHRS-1200A.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-1200A 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,
its may caused 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 ".
2、 Power and Signal Connections
FY-AHRS-1200A 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-1200A factory default serial
port baud rate is 19200, the output data refresh rate is 20Hz.
Recommended operating voltage 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.
3、Demo Software Installation and Use
The demo software program's document of FY-AHRS-1200A is AHRS test software.exe, after
complete the installation, the interface is as follows:
