Remote and auto-input switching connector — This 5-pole, 3.5 mm captive
screw connector (labeled "Remote") 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
page 7).
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
• The power supply must not be permanently fixed to the building structure
or similar structures.
• The power supply must not be located within environmental air
handling spaces or the wall cavity.
• The installation must be in accordance with the applicable provisions
of the National Electrical Code ANSI/NFPA 70, Article 725 and the
Canadian Electrical Code, Part 1, Section 16.
• The power supply must be located in the same vicinity as the Extron
AV processing equipment in an ordinary location, Pollution Degree 2,
secured to a podium, a desk, or an equipment rack within a dedicated
closet.
• Always use a power supply specified for the SW HDMI by Extron.
Use of an unauthorized power supply voids all regulatory compliance
certification and may cause damage to the supply and the switcher.
Cut the DC output cord to the length needed.
Strip the jacket to expose 3/16 inch (5 mm) of the conductors.
CAUTIONS:
• Exposing more than 3/16 inch (5 mm) of the copper wires
could allow the stripped wires to touch each other, causing a
short circuit. This could result in the external DC power supply
overheating and burning.
• Stripping the wires to expose less than the recommended amount
may cause them to slide out of the connector too easily, even if
they are tightly pinched by the captive screws.
• Do not tin the stripped power supply leads before attaching the
captive screw plug to them. Tinned wires are not as secure in the
captive screw connectors and can be easily pulled out. They may
also break after being bent several times.
Slide the leads into the supplied 2-pole captive screw plug and secure them, using a
small screwdriver.
WARNING: The two power cord wires must be kept separate while the power
supply is plugged in. Remove power before wiring.
