Powering Up
When applying power to the ISM 824, the unit undergoes a start-up self testing
sequence as follows:
• The LCD screen lights, and displays “Extron Electronics” for 1 second.
• The LCD displays “ISM 824 Version 1.00”.
• All buttons light red, then green, then amber, and then extinguish, leaving the
Video button lit green, the Audio button lit red , and the Menu and Next buttons
both lit amber.
N
If a Universal Scaler card (ISM RGB) is installed, during power up a color bar
test briefly appears on the display device.
• The LCD begins the default display cycle.
N
The complete sequence above is also made when the unit is restarted after
firmware uploads. If the unit is reset via the front panel, the sequence starts at
the default display cycle.
Default display cycle
When in use and not in any menu mode, the LCD screen defaults to cycling
through the output configuration currently installed. The displayed content may
vary from installation to installation, depending on the installed output card
configuration. See figure 3-3 for a typical default display cycle.
