Front Panel Operations
The following paragraphs detail the power-up process and then provide sample
procedures for creating ties, changing a confi guration, viewing confi gurations,
saving and recalling a preset, muting and unmuting outputs, viewing and adjusting
the audio level, viewing and adjusting the output volume, locking out the front
panel, performing one of several resets, toggling background illumination on and
off, and reading and setting the RS-232/RS-422 Remote port settings.
Power
Apply power by connecting the power cord to an AC source. The switcher
performs a self-test that fl ashes the front panel button indicators green, red, and
amber and then turns them off. An error-free power up self-test sequence leaves
all I/O and control buttons either unlit or showing background illumination. The
lit/unlit status RGBHV or Video button and the Audio button is the same as when
the switcher was powered off.
The current confi guration and all presets are saved in non-volatile memory. When
power is applied, the most recent confi guration is retrieved. The previous presets
remain intact.
If an error occurs during the self-test, the switcher locks up and does not operate.
If your switcher locks up on power-up, call the Extron S
