Configuration Procedure

To set up a scaler, follow these steps:

and on-screen display. Many of these parameters can also be configured with SIS
commands (see page 28) or the SPCPP software (see the SPCPP help file).
Connect all input and output cabling to the scaler and apply AC power (Power Input see
page 3).
In the Output Configuration menu (page 20), set the output rate of the scaler to match the
native resolution of the display.
In the Advanced Configuration menu (page 21), open the "Test Pattern" selection.
a. Activate the "Alternate Pixel" pattern and adjust the Aspect Ratio and View Mode on the
display for "1 to 1" or "pixel for pixel" mode. Once this is complete, there should be no
vertical bands of noise, and there should be perfect alternating columns of one on, one
off pixels.
b.
Activate the "crop" pattern and, if necessary, adjust the centering controls on the display
until all four crop lines are visible (do not adjust size or aspect ratio on the display). The
crop pattern can now be disabled or left on for a reference when setting up various
inputs.
Apply an input signal. In the "Input Configuration" menu (page 19), ensure the Total Pixels,
Active Pixels, and Active Lines values match the current input signal.
NOTE: Some input resolutions may not be detected properly because they appear
identical to existing resolutions in terms of Total Line Count and H/V rates. These
resolutions must initially be set up manually. To do this, see the Input Rates table on
the next page and set the Total Pixels to match the current input resolution. Then apply
an Auto Image from the menu (see page 16). Ensure that the source has a full screen
image visible before activating the Auto-Image.
Most inputs can be quickly set up using the Auto-Image function (page 16). Some non-
standard resolutions, or dark content may require manual adjustments of Active Pixels,
Active Lines, H/V Start, and Phase (see Input Configuration on page 19).
For the RGB-HDMI 300 A model only, use the Input Configuration menu (page 19) to adjust
the audio gain and attenuation and set the audio signal delay to compensate for delays to
the video signal introduced by other signal processors and display devices in the system.
NOTE: The RGB-HDMI 300 A automatically delays audio by approximately 15 ms to
compensate for internal video processing.
Once the input is sized and centered correctly, navigate to the Picture Controls menu
(see page 17) if any adjustments to Brightness, Contrast, Horizontal and Vertical Position
(nominally 0, 0), Horizontal and Vertical Size (nominally match the current output resolution),
Detail, or Zoom are required.
Repeat steps 4 and 5 for each additional input source and resolution.
NOTE: To adjust the Aspect Ratio, use the Advanced Configuration menu (page 21)
and activate the appropriate Aspect Ratio Test Pattern. Using the test pattern as a
template, align the image, using the Size and Position controls under Picture Controls
(page 17). Once the image is satisfactory, the Picture Control settings can be stored
for future recall in a User Preset (see page 18).
If Auto Memory (see page 22) is enabled, these settings are recalled automatically the next
time the input is detected.
