The CVG -724xl also has the following user selectable output pixel rates:
480p, 720p, 1080i and 1080p. Each Presentation Switcher / Scaler:
Digitally reprocesses the signal to correct mastering errors, and regenerates the
video at a higher line and pixel rate format, providing native-resolution video for
LCD, DLP and plasma displays
Up- and down-scales any graphics resolution to any other resolution3
Incorporates a unique graphics-scaling engine with image enhancement
algorithms, which are built into the firmware
Is specifically designed to improve video quality by reducing chroma noise

Includes an OSD (On-Screen Display) – for making adjustments – that can be
located anywhere on the screen, and can be doubled in size
For example, the OSD can be used to deactivate the source prompt, choose the
color of the blank screen, and choose from three seamless switching image
transition speeds
Includes seven4 multi-functional INPUT SELECTOR buttons that can cycle
between selecting a source, freezing that source, or deactivating that source (and
displaying a blank screen), if programmed to do so5
Includes a BLANK button, a MUTE button; a FREEZE button; a RESET TO
VGA button (to hardware-reset the output resolution); and a PANEL LOCK
button6
1 This is not a standard VESA resolution and its parameters vary from manufacturer to manufacturer. Therfore, use this
resolution with caution. It is also possible to use the parameters of this resolution in combination with the User Defined
resolution. There is also an RS-232 command for this resolution
2 Recommended for advanced users only – non-standard settings may not be recognized by the display device
3 For example, scaling a VGA input to an UXGA output, or an SXGA input to an SVGA output

Before Installing on a Rack
5 Installing on a Rack
This section describes what to do before installing on a rack and how to rack
mount.
How to Rack Mount
Before installing on a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5 to +45 Deg. Centigrade
Operating humidity range
Storage temperature range
Storage humidity range
When installing on a 19" rack, avoid hazards by taking
care that:
It is located within the recommended environmental
1
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
Once rack mounted, enough air will still flow around the
2
machine.
The machine is placed straight in the correct horizontal
3
position.
You do not overload the circuit(s). When connecting
4
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the product
label.
The machine is earthed (grounded) in a reliable way
5
and is connected only to an electricity socket with
grounding. Pay particular attention to supply
connections other than direct connections to the
branch circuit (for example, the use of power strips),
and that you use only the power cord that is supplied
with the machine.
5 to 65% RHL, non-condensing
-20 to +70 Deg. Centigrade
5 to 95% RHL, non-condensing
CAUTION!!
To rack-mount a machine:
1
Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the machine
(3 on each side), and replace those
screws through the ear brackets.
Place the ears of the machine
2
against the rack rails, and insert the
proper screws (not provided) through
each of the four holes in the rack
ears.
Note that:
In some models, the front panel
may feature built-in rack ears
Detachable rack ears can be removed
for desktop use
Always mount the machine in the rack
before you attach any cables or
connect the machine to the power

8.5.9.1 Setting an Input to a Non-standard Resolution (Example)
When connecting a source with a non-standard resolution, you have to set
your scaler to this resolution so it will correctly identify this source. The
Advanced mode lets you set up to three non-standard resolutions. To set an
input to a non-standard resolution, for example to 1100x800, do the
following:
1. Connect the source (with the non-standard resolution, in this example –
1100x800) to the appropriate input connector on your scaler and press the
appropriate INPUT SELECTOR button.
2. Connect the VIDEO OUT 1/2 HD15F connector to a video acceptor.
3. Turn the machines ON.
4. Press menu, go to Utility>Advanced> Mode Define, and press ENTER.
5. Scroll to Measure Mode, press ENTER and select User Define.
6. Set H Active to 1100 and V Active to 800, and set the remaining
parameters according to the input data.
7. Scroll to the Save Mode and save the new resolution.
8. Open the Information screen and check that the new resolution appears in
the Main Source line2 (see Figure 43).
1 You can save up to three settings
2 Note that for the Scaler to correctly read the input, its OCLK value should be different from that of any other defined input
of the scaler

10 CVG-724xl Communication Protocol
This protocol includes two types of commands: 3 bytes and 4 bytes.
In the 3 bytes command type, the scaler operates in a fast mode because it does
not save the information immediately. The sent command is executed
immediately, but the status of the scaler is saved in the non-volatile memory only
after 30 sec of no activity.
In the 4 bytes command type, the scaler executes the save process immediately
after each command. This operation consumes more time (adding about 2 sec).
Set and Get command:
Set Command: YControl_TypeFunctionParamCR
Reply: ZControl_TypeFunctionParamCRDone>CR
Get Command: YControl_TypeFunctionParamCR
Reply: ZControl_TypeFunctionParamCR
Example:
1. "Y 1170-127CR" -> set Contrast value. (4th byte is between 0 and
127).
"Z1170-127CR>" --> Reply value
"DoneCR" --> command setting success
2. "Y4210-17CR" -> get current output resolution. (4th byte is
between 0 and 17).
"Z4210-17CR>" -> Reply value
3. "Y035CR" -> Volume down. Each time we apply this command will
decrease the volume level by one step.
"Z035CR>"-->Reply value
"DoneCR" --> command setting success
Definition:
: ASCII Code 0x20
CR: Ascii Code 0xD or 0xA
After set type Command setting, system will respond a string as "Done"
