3.1.2.2 Making a tie by Output

Video and Audio to follow each other

Make sure both VID and AUD LEDs are lit, indicating that your changes will be

synchronized (i.e. audio and video are from the same input).

Press and release any Output button, the backlit LED of that button will light, and

all the backlit LEDs for the input tied to it will light up solid. At this point,

pressing any output buttons will be breaking or making connections.

To disconnect a tie, press the lit input button once. To make a new tie, press any

of the unlit input buttons. The new input LED will be blinking to indicate a

pending change of state. If you change your mind simply press the blinking input

LED again and it will go back to its previous state.

When you are done, press ENTER to execute and save the changed route. If you

wait too long (8 seconds of inactivity) your changes will be lost and all the input

and output LEDs will go out.

Video only or Audio only

Press and release the AUD and/or VID buttons so that the backlit LED of the

desired button is lit and the other one is off. Follow the same procedure as

described above.

3.1.3 Recalling Presets (routing patterns)

The number of presets accessible from front panel is the same as # of inputs

(however through the IP or Serial port, the unit can store and recall up to 16

presets even for an 8 input Model)

Press and release the Preset button. The button will light up solid. Then press and

release the input button (it will light up) and hit ENTER. You have 8 seconds to

hit ENTER or the action will be cancelled. This will recall the desired preset tie

pattern.

Note that a recalled preset replaces the current tie configuration, which will be lost

unless it has been stored as another preset.

3.1.4 Saving Presets (routing patterns)

The current tie configuration can be saved as a preset to be called up later on.

To save the current AV routing pattern, press and hold the PRESET button for 3

sec, the backlit LED will start flashing (this means that save preset function has

been activated). Press the desired input button to save the preset (the button with

light up). Then hit the ENTER button to complete the operation. Again, you have

8 seconds to complete this sequence.

3.1.5 Disconnecting all AV outputs (blank preset)

There is a hidden blank preset (think of it as Preset #0) in the system that can be

very useful in clearing all ties. A blank preset is a preset without any ties selected

in it. To Recall a blank preset, press and release the Preset button, press and hold

the ARROW UP () button, and simultaneously press the ARROW DOWN ()
