Operation, cont’d

If another input button is pressed and released, the level value for the current input is saved and level value for the newly selected input is displayed.

EPress and release the Audio button. The Audio LED stops blinking and the View () LED (if lit), the Esc () LED (if lit), the selected input LED, and all output LEDs turn off.

Both the RGBHV and Audio LEDs light.

Front panel security lockout (executive mode)

The front panel security lockout limits the operation of the CrossPoint switcher from the front panel. When the switcher is locked, all of the front panel functions are disabled except for the view-only mode functions. See Viewing a configuration on page 3-8. Other than in view-only mode, if the user pushes a front panel button when the switcher is locked, that button’s associated LED flashes twice and goes out.

To toggle the security lockout on or off, press and hold the RGBHV and Audio buttons for approximately two seconds. The RGBHV and Audio LEDs blink twice to indicate the mode change. Release the RGBHV and Audio buttons. To toggle the lockout state again, press and hold the RGBHV and Audio buttons again.

System reset to factory defaults

To reset the switcher to the factory default settings, press and hold the Esc button on the front panel while AC power is being applied. Continue to hold the Esc button until the power up sequence is completed (all LEDs turn off, the Video and Audio LEDs turn on, the Esc LED blinks, and the Power LED (if equipped) turns on). System reset clears all ties and presets and sets all audio gain levels to unity gain (+0dB).

Rear Panel Controls

The CrossPoint 168 and 1616 have sync termination switches on the rear panel for

16

inputs 1, 3, 5, and 7. The switches provide a way to condition

 

non-TTL sync levels greater than 5 Vp-p, enabling the sync to be

1 3 5 7

properly passed from input to selected output(s). The

15

CrossPoints have two sets of sync termination switches; one for

 

horizontal or combined sync and a second set for vertical sync.

16

Each switch provides the option of selecting either 510 ohms or

 

1 3 5 7

75 ohms. The 75 ohms position is required only for an input

 

with non-TTL sync, greater than 5V p-p. The normal position is

510 ohms.

An input that produces an out-of-sync display, a display that is rolling vertically and/or tearing horizontally, could indicate a non-TTL sync input. A device is known to output non-TTL sync levels (greater than 5V p-p) should be connected to one of the inputs with sync termination, and the termination switches for that input should be set to the 75 ohm position. If you’re not sure, check the specifications in the user’s manual for the input device.
