Three-Input HD Video Scaler for HDMI and VGA Signals

The Atlona AT-HD-SC-500 is a video scaler with built-in 3×1 switcher for HDMI and VGA signals. It features two HDMI inputs and a VGA input with a 3.5mm audio connector. It features automatic display control using CEC, IP, and RS-232 plus auto input selection.

The scaler is designed to take video signals from switchers, PCs or laptops and scale them to an HDMI output at a wide-range of HDTV and PC resolutions, up to 1080p/60Hz and WUXGA (1920×1200).

The AT-HD-SC-500 can be the central component of a small, automated AV system. Automatic display control turns on the display automatically whenever a source is connected. When the source is removed, the display is turned off. Volume is controlled by using the front panel buttons. Automatic input selection on the AT-HD-SC-500 works by sensing the presence of any video signal. With automatic input selection, manual control systems can be eliminated. Input selection can also be controlled from the front panel, RS-232, or TCP/IP commands.

Automatic Display Control

Offering first-of-its-kind display capabilities, the AT-HD-SC-500 allows display control using CEC, TCP/IP or RS-232 signals. This means that many more types of displays can be controlled, costs are reduced, and that wiring is simplified. In a commercial setting, when a switcher is integrated with a display, the AT-HD-SC-500 forces the display to power on automatically when a laptop is connected. At the end of the presentation, when the presenter disconnects the laptop, the AT-HD-SC-500 forces the display to power off. Ease of presenter interaction with the system and the savings incurred by auto-display shutdown provide a significant return on investment.

  • CEC – The AT-HD-SC-500 features Consumer Electronics Control (CEC) providing simplified display control for a significant reduction in the cost of the display (compared to an RS-232 controlled display). CEC is a communication channel incorporated in the HDMI specification allowing connected devices to control each other.
  • TCP/IP  – The LAN port on the AT-HD-SC-500 not only allows it to be managed but also allows the scaler to control a display that is connected to the same network. The scaler is able to route commands over IP for automatic display control to compatible displays. Devices must be connected to a router to manage IP addresses.
  • RS-232  – Many displays including projectors, commercial flat panel displays, and some consumer displays can be controlled using the RS-232 signal directly from the switcher. The scaler is able to send commands using RS-232 for automatic display control to compatible displays.  
  • FLEXIBLE, POWER BUTTON – The power button on the front panel can be set to either turn the AT-HD-SC-500 on/off or it can be set to control the attached display. In addition to using the front panel power button, display on/off commands can be triggered automatically based on presence of video signals, or by a third-party control system using either TCP/IP, RS-232, or IR signals.
  • SCALER OR DISPLAY VOLUME CONTROL – Volume control buttons on the front panel can control either the analog audio output of the AT-HD-SC-500 or they can be set to control the volume of any device that allows volume control using TCP/IP or RS-232, such as a flat panel display, DSP, or another switcher. This gives great flexibility to the system design.
  • MULTIPLE POINTS OF CONTROL – Since all these commands can be sent using TCP/IP, it becomes simple to have multiple control points in a larger system. The AT-HD-SC-500 could be used as an input device for an AT-UHD-CLSO-824 and the buttons would then be able to manage a variety of functions such as “Show me” and volume.

Reliable Auto-Switching

Automatic input selection on the AT-HD-SC-500 detects an active video signal, rather than looking for the 5-volt, hot plug signal. This means that devices such as DVRs, DisplayPort adaptors and other devices that keep the 5-volt hot, no longer trigger the automatic input selection. This gives far more reliable performance with these products.

Configuration, maintenance and updates are performed using Atlona’s WebGUI, AMS IP management system, or OSD. Set-up options include HDCP status, variable preferred input resolutions, output resolution, plus control of brightness, contrast, saturation, hue and sharpness. The AT-HD-SC-500 is ideal for applications where multiple signals with different resolutions must be optimized for a display.

Compact scaling switcher

The AT-HD-SC-500 combines a scaler with multiple inputs and automatic input selection capabilities for use in a small system with HDMI and VGA sources along with audio features that include analog de-embedding, volume control, and equalization.

The AT-HD-SC-500 also supports the Atlona Management System (AMS), a powerful network software platform that integrates product configuration, management and updating. Specially designed for IP-controllable Atlona Products, the Atlona Management System reduces installation time and enables remote monitoring and support.  To learn more please visit AT-SW-AMS.

The AT-HD-SC-500 is ideal for:

Complete System Applications

The three-input scaler accommodates one or two HDMI sources plus a VGA source for classrooms, huddle rooms, and small conference rooms. The front panel control buttons can be used for control of inputs or show me functions. The compact form factor enables under-surface mounting at a desk, table, or lectern. Audio de-embedding on the scaler provides professional, balanced connections to a small amplifier and speakers for better audio.

Expanding System Capabilities

The scaler can also be used as an input device on a switcher that doesn’t have a VGA input such as the AT-UHD-SW-52ED. The device also works well as an output scaler for the AT-UHD-CLSO-824 matrix switcher.

*Consumer Electronics Control (CEC): Atlona does not guarantee the function of CEC with all televisions.  We can confirm proper operation with many current Samsung, Panasonic, and Sony TVs. Many manufacturers do not support the CEC “off” command when sent from a source and older TVs use proprietary commands. Atlona only supports those TVs that follow CEC command structure from HDMI 1.2a and support the “off” command when issued by a source. We encourage any dealer to get evaluation product from Atlona prior to designing a system around this control technology or be prepared to use other methods to control their displays if Atlona CEC is not compatible with the installed displays.
