SW HDMI Series • Introduction 2
• Rack and furniture mounting — The SW HDMI Series can be mounted on a rack
shelf or under a desk or podium with an optional mounting kit.
• Remote configuration and control — The switcher can be configured via an RS-232
or USB connection via SIS commands (see Remote Communication and Control
beginning on page 21).
• EDID Minder — A proprietary EDID (Extended Display Identification Data) management
process from Extron, the EDID Minder manages the EDID between a digital display
device and one or more input sources. By maintaining continuous EDID communication
with all sources, EDID Minder ensures that digital sources power up properly and
maintain their video output, whether or not they are actively connected to the digital
display device.
• EDID modes — Either of the following EDID modes can be selected using SIS
commands:
• Automatic, in which the SW HDMI reads the EDID data when a display is
connected and stores the data in memory (default mode)
• User-assigned, in which you can assign one of 48 factory-provided EDID files
to each input. Four undefined memory slots are also provided, to which you can
save the EDID of connected displays as additional EDID files. The assigned EDID
does not change if a different display device is connected. This mode is useful for
troubleshooting purposes.
Each time power is applied to the output device or when the display is replaced, the
SW HDMI either reads the EDID information from the display or reloads the user-
assigned EDID information. It then writes the information to non-volatile memory on the
inputs. The input devices can read this information as they reboot (see EDID Modes on
page 17 for more information).
• Output compatibility correction — The SW HDMI monitors the EDID on the
connected output device to ensure that it is compatible with the currently selected input
signal. The following corrections are made to the signal as necessary each time an input
is selected:
• Interface format: If the connected output device is DVI and the selected source is
HDMI, the signal is reformatted for DVI. If the output device is an HDMI device, no
reformatting is necessary because HDMI is backwards compatible with DVI.
• Video color bit depth: If the connected output device does not support the color
bit depth of the selected source signal, it is truncated to the next level down that is
supported. For example, 12-bit >10-bit > 8-bit. Bit depth truncation can be forced
via SIS commands to always downgrade to 8-bit depth, disabling deep color.
• IR remote control (optional) — The hand-held IR 102 Remote Control can control
the SW HDMI via infrared signals that it sends to the switcher from a distance of up to
30 feet (9 m).
• Front panel security lockout (executive mode) — To prevent unauthorized access
to the switchers, the front panel controls can be locked via the front panel buttons or
SIS commands (RS-232, USB, and IR control remain available).
• Input cable equalization — Automatic input cable equalization compensates for
signal loss when long cable assemblies are used.
• Power supply —
• SW2 and SW4 HDMI: An energy-efficient, external 12 VDC, 1 A universal power
supply with a 2-pole captive screw connector accepts 100 to 240 VAC.
• SW6 and SW8 HDMI: An 50-60 Hz, internal universal power supply with a
standard IEC connector accepts 100 to 240 VAC.
