Introduction to SIS

The HDMI DA2 accepts SIS commands from a host device such as a computer running the Extron DataViewer utility or other control system. The host device can be connected to the 3-pole captive screw connector on the rear panel or to the config port on the front panel.

The protocol is 9600 baud, 8 data bit, 1 stop bit, and no parity.

NOTES:

•The wiring in the RS-232 cables crosses over so that the HDMI DA2 transmit (Tx) wire connects with the control device receive (Rx) and vice versa.

•Only one serial port can be used at a time. If the front port is in use, the rear captive screw connector must be disconnected from the computer or other control device. Likewise, if the captive screw port is in use, the config port on the front panel must be disconnected from the computer or other control device.

SIS commands consist of strings (one or more characters per command field). Unless otherwise stated, upper and lower case characters can be used interchangeably. Commands do not require any special characters to begin or end the command string. Each response from the HDMI DA2 ends with a carriage return and a line feed (CR/LF = ]), which signals the end of the response character string.

When the HDMI DA2 is first switched on, it sends the message:

NOTE: This response is only seen when the control computer is connected by the rear panel RS-232 control port.

HDMI DA2 specifications

The Extron Electronics HDMI DA2 is a high-performance distribution amplifier designed to deliver pristine HDMI signals to multiple display devices. Ideal for a variety of applications, including classrooms, conference rooms, and control centers, this device ensures that high-definition video and audio are flawlessly transmitted without degradation over distance.

One of the standout features of the HDMI DA2 is its ability to support resolutions up to 4K at 60Hz, enabling it to handle the most demanding video content. With its advanced signal processing capabilities, the DA2 ensures that the integrity of the signal is maintained, allowing for crystal-clear images and sound.

The DA2 is equipped with two HDMI outputs, allowing users to distribute a single HDMI source to two different displays simultaneously. Each output is capable of driving long cable runs—up to 50 feet for 4K signals—thanks to its robust signal amplification technology. This is especially beneficial in larger environments where displays may be located at significant distances from the source.

For added convenience, the Extron HDMI DA2 features EDID (Extended Display Identification Data) management, which allows the device to communicate effectively with connected displays. This ensures that the source and display can agree on the optimal video settings, enhancing compatibility and performance across diverse equipment.

Another notable characteristic is the automatic input switching feature, which allows the device to seamlessly switch between multiple HDMI sources if used in conjunction with other Extron products. This is particularly useful in situations where multiple devices may need to be accessed without the hassle of manual intervention.

The HDMI DA2 is also designed with ease of use in mind. It includes LED indicators that provide users with real-time feedback on power, input selection, and signal status. This streamlined approach helps in quickly diagnosing any issues that may arise during operation.

In terms of installation, the DA2 is compact and rack-mountable, making it a versatile choice for any AV system setup. With its rugged build quality and reliability, the Extron HDMI DA2 is tailored for professionals who demand high performance and dependability from their audio-visual equipment. Overall, this HDMI distribution amplifier is a critical component for any AV system requiring superior signal management for multiple displays.
