Functions
IC IO @ is "H" in REW mode and then @ : H and @:
L and the motor turns in the reverse direction.
IC 10 ® is "H'' in FF mode and the @ : "H" and
® : "L" and the motor turns in the normal direction.
In the PLAY mode, IC IO ® becomes "H" and the
motor turns, but voltage © changes to voltage (SY)
D16 as TRIS is turned on and voltage @ is reduced to
SY, thus determining the take up tension.
With GX-FSI, F31, FF input is @ and REW input
is ®·
Only the outputs of @ and ® are reversed and the
function remains unchanged.
