QS-FPC 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 rear panel 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 (if so equipped)
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
defi ned by the system confi guration.
• Systems with audio — RGBHV/Video and Audio both lit
• Systems without audio — RGBHV/Video lit and Audio unlit
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. BME 0, upon power up, issues a map refresh command to all slave
BMEs to restore the current confi guration.
N Because BME 0 maps the slave BMEs upon power up, either all BMEs should be
If an error occurs during the self-test, the switcher locks up and does not operate.

4. Press and release the Enter button to accept the tie.
5. Repeat steps 1 through 4 to create additional ties.
powered up simultaneously or BME 0 should be the last BME turned on.
Also, if any slave BME loses power, you need to issue any front panel command
or simply cycle BME 0's power to restore the current confi guration.

Input buttons and output buttons light or blink amber to indicate video
and audio ties, green to indicate video only ties, and red to indicate audio
only ties.
To indicate potential ties, output buttons blink the appropriate color
when an input is selected.
To indicate current ties, output buttons light steadily the appropriate
color when an input is selected.
To clear unwanted outputs, press and release the associated lit output
buttons. To indicate potential unties, output buttons blink the appropriate
color when an output is deselected but not untied from the input.
