Automated adjustments

Img X3

The Auto Image feature has been turned on or off from the front panel for all input selections. X3 is the on/off status.

Aut X3

The auto presets feature has been turned on or off from the front panel for all input selections. X3 is the on/off status.

Enh X3

The enhanced mode feature has been turned on or off from the front panel for S-video or composite video tied to both outputs. X3 is the on/off status for the two outputs.

X2 Reconfig

The input selected for the X2 output has been adjusted using the Auto Image feature or a user preset.

Host-to-Switcher Instructions

The switcher accepts SIS commands through its RS-232 port and/or its Ethernet port. SIS commands consist of one or more characters per command field. They do not require any special characters to begin or end the command character sequence. Each switcher response to an SIS command ends with a carriage return and a line feed (CR/LF = ), which signals the end of the response character string. A string is one or more characters.

Switcher Error Responses

When the switcher receives an SIS command and determines that it is valid, it performs the command and sends a response to the host device. If the switcher is unable to perform the command because the command is invalid or contains invalid parameters, the switcher returns an error response to the host. The error response codes are:

E01 — Invalid input channel number (too large)

E10 — Invalid command

E11 — Invalid preset number (too large)

E12 — Invalid output number (too large)

E13 — Invalid value (out of range)

Using the Command/ Response Table

The command/response table begins on the next page. Except for the gain and attenuation settings and the filter settings, upper or lower case letters are acceptable in the command field. The table at right shows the hexadecimal equivalent of each ASCII command.

With the exception of the audio gain and attenuation (G and g) and horizontal and vertical filtering (D and d) commands, the SIS commands are not case sensitive.

ISS 408, ISS 108 specifications

Extron Electronics is renowned for its contributions to the audiovisual industry, providing high-performance devices that meet the demands of professional environments. Two prominent products in their lineup are the ISS 108 and ISS 408 image scaling switchers, which are designed to enhance the management and quality of video signals in various applications.

The Extron ISS 108 is an 8x1 image scaling switcher that allows users to seamlessly switch between multiple video sources while ensuring high image quality. One of its main features is the ability to support a variety of video formats, including resolutions up to 4K. This versatility is crucial for applications in education, corporate settings, and events where different video sources may be required.

In terms of technology, the ISS 108 is equipped with advanced image scaling capabilities that improve the visual quality of the content being displayed. The device utilizes Extron's patented Vector 4K scaling technology, which enhances the clarity and detail of the images while maintaining the integrity of the source material. This technology is invaluable in environments where every detail matters, and it ensures that presentations are delivered at their best quality.

The ISS 408, on the other hand, takes the capabilities of the ISS 108 and elevates them further by offering 4x1 switching capabilities. This enables users to connect up to four video sources, giving them more flexibility in content management. The ISS 408 also supports 4K video resolutions, further solidifying Extron's commitment to delivering high-quality solutions.

Both models are designed with user-friendly interfaces, allowing for easy operation and integration into existing AV systems. They offer extensive control options, including RS-232 and Ethernet, enabling users to incorporate them into automation systems and control environments efficiently.

Another important characteristic of the ISS series is their built-in security features, such as password protection and lockout modes, which are essential for maintaining the integrity of sensitive content being delivered in corporate or educational settings.

In summary, the Extron ISS 108 and ISS 408 provide powerful solutions for image scaling and video switching. With advanced technologies like Vector 4K scaling, robust connectivity options, and intuitive control interfaces, these devices stand out as essential tools for any professional audiovisual application. Their focus on quality, flexibility, and security makes them ideal choices for enhancing video presentations in various environments.
