Extron electronic 450 manual Dsvp Data Display

Audio output volume (audio models) — The audio volume of each output can be displayed and adjusted through a range of full output to completely silent from the front panel or under serial port or Ethernet control.

Digital Sync Validation Processing (DSVP) (CrossPoint) — In critical environments or unmanned, remote locations, it may be vital to know that sources are active and switching. The Extron DSVP confirms that input sources are active by scanning all sync inputs for active signals. DSVP provides instantaneous frequency feedback for composite sync

or separate horizontal and vertical sync signals via the serial ports or Ethernet port. The frequency information can be displayed on any control system or in a Windows®-based control program on a local-area network (LAN) or Internet (IP) connection (see figure 3).

RGB Delay (CrossPoint) — A CrossPoint switcher can briefly blank the RGB (video) output while it switches to the sync source of the new input, and then switches the RGB signals. This allows a brief delay for the display to adjust to the sync timing of the selected input before displaying the new picture, which will appear without glitches. RGB delay, also known as Triple-Action Switching or video mute switching, is user selectable from 0 to 5 seconds, in half-second increments.

Rooming — Each switcher can be programmed to group multiple outputs to specific “rooms,” allowing them to have their own presets.
