Introduction, cont’d CrossPoint Plus Series delivers the highest performance and the most costeffective solution. Digital Sync Validation Processing (DSVP™) — In critical environments or unmanned, remote locations, it is vital to know that sources are active and switching. Extron’s exclusive DSVP confirms that input sources are active by scanning all sync inputs for active signals.
Operational flexibility — Operations such as input/output selection, setting of presets, and adjustment of audio levels can be performed on the front panel or over the RS-232/RS-422 link. The RS-232/RS-422 link allows remote control via a PC, RS-232 capable PDA, or control system. • QuickSwitch Front Panel Controller (QS-FPC™) — The CrossPoint Plus series QS-FPC feature supports touch-of-a-button input and output selection, preset creation and selection, and audio gain and attenuation control.
Introduction, cont’d Switching flexibility — Individually buffered, independent matrix switched video outputs with audio follow and audio breakaway for HVA versions. • Any input to any or all outputs • Quick multiple tie — Multiple inputs can be switched to multiple outputs simultaneously. This allows all displays (outputs) to change from source to source at the same time. • Audio follow — Audio can be switched with the corresponding video input.

CrossPoint Plus Matrix Switchers 3 Chapter Three Operation Front Panel Controls and Indicators Front Panel Operations Rear Panel Controls Worksheets
Operation, cont’d Operation Front Panel Controls and Indicators The front panel controls (figure 3-1 and figure 3-2) are grouped into two sets. The input and output buttons and LED indicators are grouped on the left side of the control panel. The control buttons and input/output (I/O) selection buttons and indicators are grouped on the right side of the panel. While the number of inputs and outputs varies depending on the size of the matrix, there are only two front panel arrangements.
Current configuration — The configuration that is currently being used (also called configuration 0). Global memory preset — A configuration that has been stored. Up to 16 global memory presets can be stored in memory. The input buttons select the desired preset memory location to load or retrieve a preset. When a preset is retrieved from memory, it becomes the current configuration. One preset can be assigned to each input button.
Operation, cont’d As a secondary function on HVA models, the Esc button increments the audio level of the selected input. In audio adjust mode, the Esc LED indicates a positive (+) gain value. A more detailed explanation of audio level adjustment is included in Viewing and adjusting the input audio level (HVA models only) on page 3-15. I/O controls When creating or viewing a configuration, you must specify whether the configuration applies to video, audio, or both.
Front Panel Operations The following paragraphs detail the power-up process and then provide sample procedures for creating ties, sets of ties, and configurations; changing a configuration; viewing ties, sets of ties, and configurations; saving a preset; recalling a preset; and viewing and adjusting the audio level. Power On all models, power is automatically applied when the power cord is connected to an AC source.
Operation, cont’d The I/O groups can be set up only by using the RS-232/422 port and either the SIS or the Windows control program. Ties between groups (an input in group 1 tied to an output in group 2) can be created under RS-232/422 control. Presets can also be created under RS-232/422 control that tie inputs and outputs across group boundaries. These presets are selectable from the front panel.
8. If the input button for a grouped input is pressed, and then the output button for an output in a different group is pressed, the associated output LED blinks twice and goes out to indicate that output cannot be tied to the input. The associated input LED remains lit. Example 1: Create a set of video and audio ties See Figure 3-5 and the following steps for an example in which input 5 is tied to outputs 3, 4, and 8. This example assumes that there are no ties in the current configuration.

Example 4 shows the process of viewing the current configuration after the steps in Examples 1, 2, and 3 have been performed.
A set of ties can also be viewed by selecting a tied output. To demonstrate this, note the number of a lit output LED and press and release the output button for an unlit (untied) output LED. Observe that all of the untied outputs light. Then press the output button for the output LED noted previously and observe that the selected output LED, the tied input LED (input 5), and the output LEDs light for all of the outputs that are tied to the input.
Operation, cont’d 4. One at a time, press and hold the output button(s) for the desired output(s) for approximately 2 seconds. The output LED(s) for the selected output(s) blink to indicate the mute or return to their previous state to indicate the unmute. 5. Press and release the View button to return to normal switcher operation. 1. You can mute video and audio, video-only, or audio-only outputs. Pressing and releasing the RGBHV and Audio buttons toggles each selection on and off. 2.

Operation, cont’d 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).
Plasma display S-video problem Extron has encountered a problem with the S-video output by some video conference codecs, when it is switched using a CrossPoint Plus. Some codecs change the DC offset on the chrominance (C) so that it is very different from the level on the luminance (Y). This can cause a plasma display to come up in the wrong size mode. With the matrix switcher taken out of the system, the plasma works fine. It looks like a Extron problem, but it is not.
Operation, cont’d Worksheet example 2: Drawing ties Figure 3-22 continues from worksheet example 1 by showing the video and audio ties that make up the configuration of preset 3, a solid ink line shows video ties, and a dashed pencil line shows the audio ties. In this example, the image of the presenter, from the main podium camera (input 1), is displayed in the main hall (output 1), to the overflow crowd in the conference room (output 4), and in the lobby (output 8).
