ABOUT VIDEO SCALING
The CXPS output slots can each be populated with a scaler card- for a maximum of nine
scaler cards possible. A Quad Dual-Link Scaler card (QDLS card) may be used in odd-
numbered slots, while a Quad Single-Link Scaler card (QSLS card) may be used in odd or
even numbered slots.
With a scaler card, the output’s image can be scaled up or down or modified to fit a display
resolution different than the native resolution of the input signal. Scaler cards also supply
the CXPS with video windowing, wall processing, and video dissolve capabilities.
The most common scaler operations are discussed below. Scaler operations are performed
using RS-232/ Telnet control.
• For more about configuring the CXPS output channels, see Chapter 3, “Configuration
Options.”
• For information on windowing capabilities, see Chapter 9, “Video Windowing.”
• For information on video dissolve features, see Chapter 10, “Dissolve and Force
Effects.”
• To learn about wall processing capabilities, see Chapter 11, “Wall Processing.”
• For a complete list of RS-232 and Telnet serial control commands, see Appendix A,
“RS-232 and 10/100T Protocol.”

AUTO-RESOLUTION DISPLAY
By default, any input routed through a QDLS card output channel is automatically scaled up
or down to fit the resolution of the connected display device. The original aspect ratio of the
input image is maintained. If this input aspect ratio is different than that of the display
device, black bars will fill areas of unfilled pixels.
Auto-resolution display is an automatic feature of the scaler card and does not need to be
programmed. This feature automatically detects the display resolution and displays any
input source at its maximum resolution and proper aspect ratio.
NOTE RS-232 commands and Telnet protocol are identical.
