firmware update
Once the status bar has progressed fully from left to right across the indicator
window, the firmware loader utility automatically resets the switcher
(figure 4-10).
If the firmward loader utility exits before the status bar has progressed
completely across the indicator window, try using a control cable with only
pins 2, 3, and 5 connected. If necessary, modify the cable by removing pins or
cutting wires.
If the firmware loader utility exits before the status bar has progressed
completely across the indicator window, the firmware may be corrupted and
may no longer respond to the Matrix Switchers Control Program. In this
condition, the firmware upload can be accomplished only by using the SIS
commands. See Loading firmware using an SIS command on page 4-9.
