PSD and output voltage
With the D-sub connector on top, the output corresponding to the horizontal position (converted output voltage of the X position) is
output from D-sub connector terminal No. 1 (V5), and the output corresponding to the vertical position (converted output voltage of
the Y position) is output from D-sub connector terminal No. 2 (V4).
