Output Accuracy - The digital to synchro conversion
3.5.8.4.2.1
shall be within 45 minutes. Autopilot steering and course deviation
bar conversion shall be within 10% of full scale.
Doppler Ground Speed Interface - The doppler ground
3.5.8.4.3
speed shall be input as a pulse train from Pin Y of 2J1 on RT-680/APN-153(V)
Doppler Receiver-Transmitter. The input pulse train is a negative going
4 volt pulse with respect to the Doppler Ground Speed Reference (+25 VDC).
This signal shall be converted into a digital data word proportioned to
the frequency of the pulse train and conditioned for output to the NC in
accordance with 3.5.8.4.8.
Radar Range Interface - Radar range shall be con-
3.5.8.4.4
verted from pulse width to digital data word. Radar range is input from
Radar Buffer Converter and output to NC.
Inputs - The following signals shall be put on 2
3.5.8.4.4.1
wire differential line receivers (Fairchild A9615 or equivalent)
terminated with 130 ohms dc.
