Firmware Upgrade Installation

4. Remove the top two front panel screws.

5. Lift the top cover straight up approximately five inches until you can access the fan power cords.

CAUTION

Do not touch any switches or other electronic components inside the ISS. Doing so could damage the switcher. Electrostatic discharge (ESD) can damage IC chips even though you cannot feel it. You must be electrically grounded before proceeding with firmware replacement. A grounding wrist strap is recommended.

6. Disconnect the two fan power cords from connectors J8 and J13 on the main board.

7.	Lift the top cover out of the way.

8.Perform the desired maintenance procedure. See Firmware Upgrade Installation or DVI Output Card Installation in this chapter.

9.Reconnect the two fan power cords to connectors J8 and J13 on the main board. It does not matter which fan is connected to which connector.

10. Replace the top cover on the ISS.

11. Fasten it with the screws that were removed in step 3 and step 4.

12.Rack mount the switcher if desired and reconnect all cables.

In some cases the ISS’s firmware may require replacement with an updated version. There are nine user-replaceable firmware chips, U1, U2, and U6 on the front panel circuit board and U98, U99, U100, U101, U102, and U103 on the main circuit board. The U-numbers are printed on the circuit boards. We recommend that you send the unit in to Extron for service and updates.

•Chip set U1 and U2 are replaced as a pair

•Chip U6 is replaced alone

•Chip set U98, U99, U100, and U101 are replaced as a set

•Chip set U102 and U103 are replaced as a pair

CAUTION

Changes to firmware must be performed by authorized service personnel only. Some ISS firmware updates must be performed at the Extron factory.

Replace firmware in the ISS as follows:

To prevent electric shock, always unplug the ISS from the AC power source before opening the enclosure.

1. Open the switcher. See Opening and Closing the Switcher on page 7-2.

2.Locate the firmware chip(s) to be replaced on the main or front panel circuit board (figure 7-1).

3. After you are electrically grounded, use a DIP chip puller to grasp the IC chip(s) and pull it (or them) out of the socket.

4. Align the slots of the new firmware chip(s) with the angled corners of the socket in the same orientation as the old chip(s). Gently, but firmly, press the chip(s) into place in the socket.

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.
