Wiring definition and usage instructions

A 25-pole electrical connector is used to connect the power supply, the digital output signals and the temperature sensor inside the gyroscope. The input DC power supply includes +15V, +5V and -5V, and the gyroscope output signal is two TTL level digital signals, which can be connected to the phase identification, demodulation and counting circuit to get the required angular displacement signal. There are three platinum resistance temperature sensors inside the gyroscope, by measuring the resistance value of platinum resistance, the temperature value of different points inside the gyroscope can be determined, and the gyroscope can make real-time temperature compensation when necessary. the specific wiring table of 68 laser gyroscope is as follows:

This model of laser gyroscope outputs two pulses with 90 degree phase difference through pin 8 and pin 9 respectively, the user can judge the forward and reverse direction of the carrier by counting the two pulses reversibly, and at the same time count the pulses to calculate the angle of carrier rotation. As the machine jitter laser gyro itself has a jitter signal that needs to be stripped from the actual carrier rotation signal, it is necessary to perform finite impulse response low-pass filtering (FIR) on the counting signal to extract the actual carrier rotation information. If customer has difficulty in processing by themselves, we can provide acquisition conversion card according to customer's requirement to convert the signal into the format required by customer after counting.
