To replace the firmware or install the optional DVI output card, you need to open the ISM’s case. Open and close the switcher as follows: 1. Disconnect the AC power cord from the ISM to remove power from the unit. To prevent electric shock, always unplug the ISM from the AC power source before opening the enclosure. 2.
4. Remove the top two front panel screws. 5. Lift the top cover straight up approximately 5 inches until you can access the fan power cords. CAUTION Do not touch any switches or other electronic components inside the ISM. 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.
Maintenance and Modifications, Cont’d Installing a Firmware Upgrade In some cases the ISM’s firmware may require replacement with an updated version. There are nine user-replaceable firmware chips (figure 7-2): 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. Extron recommends that you send the unit in to Extron for service and updates.
4. Align the slots of each new firmware chip with the angled corners of the socket in the same orientation as the old chip. Gently, but firmly, press the chip into place in the socket. 5. Close the switcher. See “Opening and Closing the Switcher”, starting with step 9 on page 7-3. Installing a DVI Output Card You can install an optional digital visual interface (DVI) output card in the ISS. With the card installed, a additional DVI video output 1 on a standard DVI connector.
Maintenance and Modifications, Cont’d 3. If the rear panel DVI connector opening is still covered, remove the two screws that secure the cover to the back panel and remove the cover. 4. Position the DVI card above connector J14 with the DVI connector facing toward the rear of the switcher. Ensure that the pins on the DVI card properly align with the J14 connector to prevent bending the pins. 5.
Integration Scaling Matrix Switcher A Appendix A Ethernet Connection Cabling Determining Default Addresses Connecting as a Telnet Client
Ethernet Connection, cont’d The rear panel Ethernet connector (figure A-1) on the ISM switcher can be connected to an Ethernet LAN or WAN. This connection makes SIS control of the switcher possible using a computer connected to the same LAN.
Determining Default Addresses To access the ISM switcher via the Ethernet port, you need the Extron ISM IP address. If the address has been changed to an address comprised of words and characters, the actual numeric IP address can be determined using the Ping utility. If the address has not been changed, the factory-specified default is 192.168.254.254. Ping can also be used to test the Ethernet link to the ISM.
Ethernet Connection, cont’d Connecting as a Telnet Client The Microsoft Telnet utility is available from the DOS prompt. Telnet allows you to input SIS commands to the ISM from the PC via Ethernet. Access the DOS prompt and start Telnet as follows: 1. Click Start > Run. 2. At the Open prompt, type command. 3. Click the OK button. 4. At the DOS prompt, type telnet and press display similar to figure A-3. Enter . The computer returns a Microsoft (R) windows 2000 (TM) Version 5.
Once you are logged in, the ISM returns either Login Administrator or Login User. No further prompts are displayed until you break or disconnect the connection to the ISM. Escape character and Esc key When Telnet is first started, the utility advises that the Escape character is ‘Ctrl+]’. Many SIS commands include the keyboard Esc key. Consequently, some confusion may exist between the Escape character and the Escape key.
