1.0 Introduction
The SSW-HD-4 is a 4x1 HDMI seamless video switch with multi-view capabilities
where all inputs can be shown in real-time (60 frames per second) on the output in a
variety of modes. When only one input is shown, switching between different inputs
is completely seamless (with zero delay transition). The switcher supports Input and
Output resolutions up to 1080p Full HD.
The SSW can display four Hi-definition sources on a single display and comes with
pre-configured multi-view layouts (4 equal images as shown here, or one large and 3
smaller windows in various positions).
Individual buttons for each input allow quick selection from the front panel. Control
of switching and multi-view window layouts can be accessed via Front panel, IR
remote control (included), RS-232, or a PC GUI (that controls the device via RS-
232).
The product is shipped with rack ears for 1U rack mounting.

If the SSW-HD-4 needs to be installed in a standard 19” rack, you can use the
included rack ears.
3.4 Multi View Layouts
SSW supports three different Multiview modes. The Output modes can be
configured using Front panel, IR Remote Controller PC-GUI and RS-232. When an
input is selected in Multiview mode it is considered as a primary input and the other
inputs dynamically arrange themselves in the layout as shown below. Note that Auto
Scan can be enabled in Multiview mode.
Multi View Modes
3.5 Auto Scan (Auto Switch)
The Auto Scan feature is another important feature of the seamless switcher. When
the Auto Scan feature is enabled, the SSW automatically switches to the latest input
plugged. So even if currently selected input has video and you plug in a new input, it
will switch to the new input.
In this mode, when the selected input is unplugged, the SSW automatically switches
to another input with active video (scans from input 4 to input 1).
To enable Auto Scan, hold Output Mode button for 7 Seconds or until the button
light starts blinking.

buttons blink once.
