Video Switching

Overview

This chapter discusses the various methods you can use to change between video inputs on your switcher. You can use

the following methods:

Auto Switching Mode

Manual Mode (Input selection via a physical button press)

Auto Switching Mode

Auto Switching mode is the default switching mode. With Auto Switching mode, the switcher responds to the most

recently added video input by switching the new input to display on the HDMI and DXLink output. If the currently

selected video source is removed, the next video port in numeric sequence with valid video is selected.

Note: If you reboot the switcher when Auto Switching is enabled, the switcher displays the last input selected before the

reboot. If you manually select an input with an invalid signal before rebooting, the same input with the invalid signal will

be displayed after the reboot.

Auto Switching mode is enabled by default. You can disable Auto Switching mode by using the

VIDIN_SELECT_AUTO command. See page 41 for more information on this command.

You can use the following NetLinx commands to select a video or audio input.

See the VI<input>O<output> command on page 41 for information on the NetLinx command you can use to

select the video input you want to use.

Use the AI<input>O<output> command on page 40 to select an audio input.

Note: These commands are only available for use with the SDX-510M-DX switcher.

Manual Mode

Manual mode involves making a video input selection by a physical button press. The Select button on the front of the

panel enables you to quickly scroll through all available inputs on the switcher. Each button press progresses the input

selection to the next numbered input. Once you reach the end of the available inputs, the next button press returns the

selection to video input position 1.

When in auto switching mode, if you press the select button, the video input remains on that position—whether there is

video established or not—until you press the Select button again, or a new video source is presented to another video

input resulting in an automatic switch to that video position.

All Cycle Contact Closure

The External Button/LED Control Connector (FIG. 35) is a contact closure matches the functionality of the Select button

when using a remote push button. It enables you to cycle through of all inputs where each press result in a move to the

next video input.

Group Switching (SDX-510M-DX only)

The SDX-510M-DX has two sets of groups in which the first external button LED control connector is used to cycle

through the inputs within a particular group. HDMI INPUT 1 is always the first input on both groups. Group 1 contains

inputs 1, 2, and 3. Group 2 contains inputs 1, 4, and 5. You can route the audio/video from one input within a group at a

time. You can cycle through the inputs in each group by clicking a single button module connected to the External button

connector located next to HDMI INPUT 1 on the rear panel of the device (see the External Button/LED Control

Connectors section on page 16 for more information about External button connectors.)

Note: Contact closures 3 and 5 are not tied to specific inputs, and are allowed for an auxiliary button press trigger event

notification which can be recognized by a NetLinx Master for programming purposes.
