Updating the Firmware
www.camboard.de
CAMBOARD Electronics
If your system has primary and redundant controller boards, both boards must
have the same firmware revisions installed.
The ICs that contain the firmware for the matrix switcher also contain the
memory in which presets and audio levels are saved. When you replace the IC,
these settings will be lost. You may want to record the presets and audio levels
before you replace the IC.
Replace the firmware as follows:
1.
If the firmware is being replaced on an installed controller board, remove the
board, see Removing the primary or redundant controller board in this chapter,
placing the controller board on an anti-static mat.
2.
Locate the PROM to be replaced, IC U1, U2, or U6 (figure 6-12).
Align notches.
Align notches.
U1
Figure 6-12 — PROM replacement
3.
For IC U6 — Use a PLCC IC puller to remove the existing firmware IC.
Squeeze the tool to align its hooks with the slots in opposite corners of socket
U6. Insert the hooks, squeeze gently, and pull the IC straight out of the
socket. Set the IC aside.
4.
For ICs U1 and U2 — Use your fingertips to grasp the edges of the existing
firmware IC and pull the IC straight out of the socket. Set the IC aside.
5.
Note the key (notch) of the new firmware IC. Orient the IC to match the key
on the socket, and carefully press the IC in place.
6.
If the controller board was removed from a switcher, reinstall the controller
board, see Installing the controller board in this chapter.
