DS560 Miniature Directional Sensor
The DS560 contains both a 3-axis fluxgate magnetometer and a 3-axis accelerometer， it is designed to enable high accuracy measurement of the roll, inclination and azimuth orientation angles of a system to which it is mounted.
Product Introduction:
The accuracy of roll and inclination measurement is ±0.2° .The accuracy of azimuth measurements is ±0.5 ° .
The DS560 communicates with the outside world over a serial bidirectional TTL or a RS232 interface.
Features:
Computer Interface
The computer interface of the DS560 System is a TTL level serial interface. In the standard configuration, data is transmitted to the DS560 on pin RX and transmitted out of the DS560 on pin
TX. The default baud rate is 9600 with one stop bit and no parity.
In order to communicate with an external personal computer (PC), the TTL levels of the DS560 must be shifted to the RS232 levels used by the serial ports on
PCs.The best way to determine if communication with the DS560 has been
established is to observe the presence of the DS560 sign on message that is
transmitted at 9600 baud when power is turned on. The sign on message for the DS560 is :
S/N XXXXXXX
Ver: 1.0
In the above messages the x’s represent the unit serial number.
Application:
Internal Constants
The operating characteristics of the DS560 are controlled by the value of internal binary constants. The most important constants are:
Binary Function | Data | Action |
01 | 5A | enables auto send upon power up |
02 | 02 | sensor output (in Gauss and Gees) |
04 | angle output (roll, inclination, azimuth) | |
08 | 10 | enables ASCII auto send upon power up |
09 | Baud rate lock (must be =5A if any baud rate other than 9600 is used) | |
10 | Sets baud rate | |
