The AT-HDVS-200-TX is a 3◊1 switcher for HDMI and VGA inputs with HDBaseT output. It features two HDMI inputs a VGA input and an always on 3.5mm audio connector. The AT-HDVS-200-TX 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-HDVS-200-TX works by sensing the presence of any video signal. With automatic input selection manual control systems can be eliminated.
The AT-HDVS-200-TX combines the benefits of a switcher and the advantages of Ethernet-enabled HDBaseT signal transmission over a single cable. The switcher enables input selection from the front panel RS-232 or TCP/IP commands. HDMI signals up to 4K/UHD @ 60Hz with embedded audio VGA input signals up to 1920◊1200 and control signals can be extended up to 328 feet (100 meters).
When used with the HDVS-200-RX system performance is limited to 1080p. The AT-HDVS-200-TX receives power from the AT-HDVS-200-RX scaler via Power over Ethernet. Together they create a standalone AV switching and control system with scaling for classrooms and huddle rooms.
Automatic Display Control
Offering first-of-its-kind display capabilities the AT-HDVS-200-TX 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-HDVS-200-TX 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-HDVS-200-TX 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-HDVS-200-TX 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 TCP/IP signal can be transmitted either through an independent LAN connection or through the HDBaseT connection when connected to an AT-HDVS-200-RX receiver which allows Ethernet over HDBaseT. The LAN port on the AT-HDVS-200-TX not only connects to the AT-HDVS-200-TX it also extends out the HDBaseT connection through an internal hub. A connected router is required 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-HDVS-200-TX 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.
SWITCHER OR DISPLAY VOLUME CONTROL• Volume control buttons on the front panel can control either the analog audio output of the AT-HDVS-200-TX 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-HDVS-200-TX 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.
Automatic input selection on the AT-HDVS-200-TX 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
