PXQ524 Dual/Quad Display Controller


In stock (can be backordered)


The MicroImage PXQ524 is a true high performance quad display controller designed for demanding applications. In addition to the quad display, the unit will also display two full images side-by-side unlike split screen, which only shows a portion of each image. The two images may be easily exchanged with a front panel switch. The side by side display works well with wide screen monitors where the additional black at the top and bottom isn’t as visible, maximizing display use. The MicroImage Video Systems Quad Display controller has been designed for industrial and professional applications. Operation is simplified with easy to use buttons to control commonly used functions rather than having to waste time in deep menus for common functions.

The input signals are standard composite video, in NTSC or PAL format (all must be the same format). Genlocked sources are NOT required. The source video signal can be almost any composite video signal from a studio camera to camcorders and even the output of a VCR. The system will lock to many signals, even those of less than perfect quality. Each of the four input signals has a dedicated memory area for frame synchronization.

In the dual and quad display modes, an optional border line may be selected to divide the images. This border can be set to off, black, dark gray, light gray and white via a front panel switch.

Quad displays are commonly used for security or monitoring of multiple locations or angles at once. All four images can be easily recorded onto one medium eliminating temporal issues with multiple playback recordings.

Two full images displayed side-by-side reduces the need for two monitors and and is commonly used in clinical applications such as behavioral sciences. Two subjects at different locations can be monitored and recorded with a precise time alignment.

Video conferencing typically has multiple people conversing at once and the side-by-side dual image as well as the quad display mode can be used successfully in this application.

Courtroom display systems, which are becoming increasingly popular can benefit from the full image side-by-side or quad display and remote switching capability of the PXQ524.

Two simultaneously displayed images allow for comparisons that are necessary in Forensics, Bio-Medical and industrial production. Displaying them on the same monitor allows very precise comparison. The output signal of the PXQ524 can also be sent to a video printer for a precise hardcopy.

The PXQ524 uses state-of-the-art, high performance digital signal processing (DSP) to maintain the highest quality video signals. This assures a consistent image will always be displayed. The PXQ524 will always produce both composite and S-Video signals simultaneously.

The PXQ524 family of products works with a variety of video sources and cameras. The PXQ524 will work with almost any video cameras (or other video sources) that have a composite output signal and meet the NTSC or PAL standard. Genlock is NOT required.

The standard RS232 control allows the PXQ524 to be controlled by a computer or other device or from a remote location. See the protocol definition manual for additional information.

A Rack mounting kit is available as an option.

Power is provided by a universal power supply (included) or it can be operated from +5VDC +/-5% (negative ground). The unit is packaged in a durable metal enclosure with plastic end bezels. Board Level, OEM and Custom products are also available. Please contact MicroImage Engineering for additional information.

A Rack mounting kit is available as an option. RoHS products are available for those countries that require units with RoHS compliance. RoHS units are lead-free.

The PXQ524 is available completely packaged (cased) or as a board level product for OEM applications. Power is provided by a universal desktop power supply (included with cased products) or it can be operated from +5VDC (negative ground). Board level products do not include the power supply and a 5VDC regulated power source must be provided.?
