SW HDMI Series • Installation 6
a Power connector —
• SW2 and SW4 HDMI: Plug the provided external 12 VDC, 1 A power supply into
this 2-pole, 3.5 mm captive screw connector and into an AC power outlet.
ATTENTION: Do not connect power to the switcher until you have read the
CAUTION and ATTENTION notices on the next page.
• SW6 and SW8 HDMI: Plug the provided AC power cord into this male IEC
connector and into an AC power outlet.
b Input connectors — Connect HDMI video input sources to these female Type A
single-link HDMI connectors. Data rates of up to 6.75 Gbps are supported.
• LockIt brackets: LockIt cable lacing brackets, one for each HDMI input and the
output connector, are provided with the SW HDMI. These brackets secure the
HDMI cables to the rear panel connectors and reduce stress on the connectors,
preventing signal loss due to loose cable connections. For information on
attaching the LockIt brackets, see the LockIt HDMI Cable Lacing Bracket
Installation Guide, available at www.extron.com.
• EDID information: By default, EDID is read from the output device and written
to switcher memory for each input, allowing each source to see the EDID
information for the output device even when the SW HDMI is switching between
sources.
c Output connector — Connect an HDMI display device to this female Type A HDMI
connector.
The EDID information is read from the connected output device via this connector and
is written to memory on each input whenever the output device is connected to this
port and powered on.
NOTE: The EDID information is also read and stored whenever power is recycled
to the connected output device or when the output device is replaced.
d Contact port — Plug one of the provided 5-pole captive screw connectors into this
5-pole, 3.5 mm captive screw port. On the SW6 and SW8 HDMI, plug connectors
into either or both parts of the dual Contact port. You can use this port to switch
inputs by:
• Shorting the ground pin to any of the other four pins in the connector (see
Contact Closure under “Selecting an Input” on page 15).
• Connecting a push-button contact closure device to the port (see Wiring for
Input Selection by Contact Closure on page 11).
e Remote and auto-input switching connector — This 5-pole, 3.5 mm captive
screw connector (labeled “RS-232 Auto”) can be used for RS-232 communication
with the switcher (including firmware updates) and to enable auto-input switching.
• To enable RS-232 control, connect the Tx (transmit), Rx (receive) and G
(ground) pins to the serial port of your computer (see Wiring for RS-232 Control
on page 8).
• To enable auto-input switching, short pins 4 and 5 of this connector together.
In auto-input switch mode, the switcher automatically switches to the highest
numbered active input (see Enabling Auto-input Switching on page 10).
