Delimiters: INLINE scalers can be set to recognize six sets of leading and end codes when using an
RS-232 remote: parentheses ( ), brackets [ ], braces{ }, slashes \ /, less and greater than < >, and
signs !#.
Additional RS-232 products can be connected to different delimiters; however, only the unit
matching the RS-232 delimiters transmitted from the remote controller will respond.

The IN1402 only detects the input video standard. The input horizontal scan rate and input vertical
refresh rate only indicate the normal rate for the standard detected. All other values are simply
repeated as defined by the input and output settings. Although the IN1402 detects the input video
standard and adjusts automatically (for the detected input video standard and the selected output
mode), the system will reflect any changes to these settings made by the user. This information may
be useful for setting video parameters of other video equipment connected to the IN1402.
Reset RS-232 resets all RS-232 settings to factory default.
Choosing the Optimal Output Resolution
Of all the settings on the IN1402, perhaps the most critical adjustment is the output resolution. Every
display device has an optimal or native resolution. This will vary depending on the type of display
technology, if the display has a fixed number of display elements (native resolution), the size of the
pixels, the size of the display or display screen, and even the distance of the viewer from the display
screen. Setting the IN1402 to the output resolution to match this optimal resolution for your data
display will have an enormous impact on the image quality.
Please note that the ideal resolution must also lie within the compatible scan range of the display
device. For example, some 27" - 36" presentation monitors are limited to input signals in the
30 - 50 kHz range. If the video scaler's output resolution settings are too high, the signal will not be
viewable on the display. Before selecting the output resolution, you should check the specifications
page in the operation manual for your display device to verify the compatible horizontal scan range.
The Large Screen Data projector list and Large Data Display list include signal compatibility
information for both current and obsolete models of data projectors, retro displays, presentation
monitors and plasma displays.
CRT displays: Selecting the golden resolution
While CRT displays do not have a native resolution, they will have a "golden resolution," or sweet
spot, for input signal resolution. When the video scaler is set to the golden resolution of the CRT
display, the result is a sharp, detailed image without visible scan lines. If the video scaler is set below
the golden resolution, the displayed image will have tiny black lines between the image lines. If the
video scaler is set above the golden resolution, the lines will actually overlap and the image will
appear soft and lose detail because there are more lines and pixels than the display can clearly resolve.
When experimenting to find the golden resolution for your CRT display device, it is best to begin at
the output resolution indicated in the chart on the next page. You can then try higher and lower
resolutions until you achieve the setting that offers both a solid image and excellent picture detail.
