CM8504KIT-SPCL
Firmware Upgrade Instructions
®
The CM8504KIT-SPCL is for upgrading the firmware from text to no-text in the EPROM on the
CM8504 Video Output Matrix Card in the CM8500 Series Matrix System. There are two
EPROMs included in the kit. Which one you use depends on the board installed in your
CM8500.
To change the EPROM:
1. Turn off power to the CM8500.
2. Remove the four front cover screws from the corners of the card cage front panel and
remove the front panel.
3. Use the motherboard PCB ejectors to pull and slide the main motherboard out of the card cage.
4. The CM8504 video input/output card(s) are in the slots (up to 16) closest to the front of the
motherboard. Pull up on the ejector tabs of the video card to remove it from the motherboard.
5. Locate U4 (refer to Figure 1) and remove the EPROM from its socket.
6. Remove the new EPROMs from the electrostatic protective bag.
7. Identify which board you have (refer to Figure 1), and select the appropriate EPROM:
• If your board is labeled PCB9000563 REV. G, use the EPROM labeled
PRG563SPCL-R1.3.
• If your board is labeled PCB9000563 REV. H or higher, use the EPROM labeled
PRG563SPCL-R1.4.
8. Verify that the pins on the EPROM are straight.
9. Insert the new EPROM in the U4 socket. Orient the EPROM using the alignment notch as
a guide (refer to Figure 1). Verify pin-to-socket alignment and carefully press the EPROM
into the socket until it is fully seated.
10. Reinstall the CM8504 board into the motherboard. Make sure the ejector tabs lay down
flat against the circuit board.
11. Repeat steps 4-10 for additional CM8504 boards.
12. Slide the motherboard back into the card cage and lock the ejectors into place.
13. Replace the front panel.
14. Turn on power.
