FOG based north finder measurement, precise north finder system
Electrical performance
1) Insulation resistance
The insulation resistance between the independent circuits of the gyro north finder, and between the circuit and the housing should not be less than 100 MΩ under standard atmospheric conditions.
External Interface
1.1.1 With 24V±4V power input.
1.1.2 With serial port output function, the serial port output is defined as follows:
The external communication port adopts the RS422 serial interface form, with 1 start bit, 8 data bits, 1 stop bit, no parity, and a baud rate of 9600bps. The data is in ASIC format.
