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

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.
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.

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.
