1.0 Introduction
The SW-HD-4 is a 4 input HDMI Switcher with InstaPort™ Technology from
Silicon Image enabling fast switching of four HDMI sources to a single HDMI
output. The switcher supports 4K (UHD), 3D, and 36-bit Deep Color video. Control
switching via front panel button, using IR remote control, RS-232, Telnet, or the web
GUI is built in the unit.
Auto-Switching mode is also available. In this mode the switch checks for video
connection on the inputs and switches to the first input detected.
EDID control is provided, whereby you can select the EDID content for each input
from a list of standard EDIDs or to copy the EDID from the connected display to any
input. This can be done using the web GUI or by sending RS-232 commands.
The SW-HD-4 provides a USB type A port on the back for connection of USB flash
devices for firmware upgrade. This USB connector provides 500 ma of power and
can be used to power external devices such as Google’s Chromecast or Amazon’s
Fire TV.

4.2 WebGUI Operation
As shipped from the factory (or after factory default reset), the SW-HD-4 IP address
is set for DHCP, meaning that it does not have an assigned static IP address and
when connected to a router on a LAN, the router will assign an IP address to the
device. This can speed up the setup process in most instances, the device will get a
valid IP address that matches your network, and the last octet will be unique so it
does not conflict with any other existing IP address on the network. A user can find
the IP address using the following method, and once access is established, the IP
address can be changed to STATIC (rather than DHCP) if desired.
Finding the SW-HD-4 on the compatible LAN network
o The “HRDF” (Hall Research Device Finder) Windows™ GUI is
available free from the Hall Research website’s product webpage. This
program can locate the SW-HD-4 on the network.
o Selecting any device displayed; opens a window where certain fields are
modifiable.

Click the “Save” button after making any changes.
Click the “Reboot” button to reboot the device.
SW-HD-4 internal Web pages (WebGUI)
o Access the SW-HD-4 Webpage with any compatible browser at the IP
address found above. The browser will open with the devices STATUS
tab displayed. Click the tabs at the bottom of the screen to access the
other tabs.
o Status Tab
The tab shows status of the device along with output information.
POWER and ROUTING are controllable.
o EDID Control Tab
This tab shows the EDID routing status. Each INPUT can have a
unique EDID or the EDID from the connected SINK.

o Settings
This tab shows the current HDCP Control settings, WEBGUI Input
and Output names as well as buttons for Reboot, Factory Reset,
Panel Lock and Auto Switching. If the Panel Lock is enabled, the
button is highlighted and the AUTO SWITCH button is disabled.
o Network Configuration
This tab shows the current network settings. To save any changes
made, click the “Save” button. The browser may prompt the user to
confirm the settings
.
4.3 Auto Switching
Auto switching with priority is another important feature of the switcher.
Notice The Switcher can disable HDCP support for any input forcing the source to
send unencrypted content when allowed (some sources add HDCP even if the
content shown is not protected). When the input does not have HDCP, the
output will not have HDCP. This is a useful feature for connecting the output
to devices that do not support HDCP such as video conferencing gear.
4-port HDMI Fast-Switch with IP Control
12
In Auto mode, the SW-HD-4 scans all inputs and automatically selects the active
input.
Priority is based on position with #1 input having the highest priority (so if more
than one input has video, in Auto mode, the input with lowest port number will be
selected).
Auto Switching Mode can be enabled and disabled by external command (RS-232,
Telnet, or WebGUI), or via the front panel pushbuttons. Auto mode cannot be
changed using the IR remote.
• To enable, Press and hold the INPUT button for 3 seconds. After releasing
the INPUT button, the front panel INPUT LEDs blink to indicate that
AUTO mode switching is active.
• To Disable, Press and hold the input button for 3 seconds. After releasing
the INPUT button, one of the front panel INPUT LEDs will be illuminated
solid showing the selected input.
4.4 Front Panel and IR Remote Lock
Front panel buttons of SW-HD-4 can be locked via WebGUI, RS232, or Telnet to
prevent users from switching or changing modes. When enabled, attempts to change
the auto mode, input selection, or power status will be ignored. The only way to reenable the IR Remote and the front panel buttons is to send an unlock command
from WebGUI, RS232, or Telnet (factory default also unlocks the front panel).
4.5 Factory Default
If the POWER and INPUT button is pressed simultaneously for 3 seconds when the
unit is operational with the power already applied, the IP parameters are reset to the
FACTORY DEFAULT values which results in Power light blinking once.
The default IP address is set to DHCP. The Hall Research Device Finder (HRDF)
can be used to find the SW-HD-4 on the network.
Notice When Auto Switching mode is ENABLED, just clicking the front panel
INPUT button or the IR remote buttons will have no effect (i.e. the unit will
remain in Auto mode), However Selecting inputs via WebGUI, RS232, or
Telnet commands will cancel the Auto Switching mode and the unit will select
the desired input.
Notice The IP address can be changed from DHCP to Static using the HRDF software
or using external control commands (WebGUI, RS232, or Telnet).

4.6 EDID Settings
EDID Modes can be selected by choosing ALL option (a set of 9 EDID predefined
settings for all the inputs) or APPOINT option (Each Input with unique EDID) from
the WebGUI, RS232 or Telnet commands.
