IR 901 Infrared Remote Control
The IR 901, shown at right, replicates all of the front
panel controls except the Menu and Next buttons. If
Executive mode has been enabled on the QSD 204,
input selection and adjustments can still be made from
the IR 901, but you must use the QSD 204’s front panel
or the Windows-based control program (via an RS-232
device) to configure and program the decoder. See
chapter three, “Serial Communication”, for details.
The topmost part of the IR 901 features three Aspect
Ratio Preset buttons, a Freeze button and four input
selection buttons (1, 2, 3, 4). Inputs 5 and 6, and the
Take button are
not functional. The middle portion of
the IR 901 features the size and centering buttons. The
bottom part contains the adjustment controls for color,
tint, brightness, contrast, and detail adjustments. The
sharpness buttons are
not functional.
