Recommended list of gyros
(other types of gyros may also be used).
Chassis connector as seen
from the rear of the MCU.
The gyro is connected to the GYRO (P12)
outlet located on the rear panel of the MCU.
See diagram for pin configuration.
Synchro gyro:
10 - 125V rms sinusoidal
50 - 400Hz
Stepper gyro:
5 -150V rectified sine, 120 - 400Hz
or DC, 72 transitions per sec.
Signals may be positive or negative
referred to COM (return).
