ATTENTION : Les deux cordons d’alimentation doivent être tenus à l’écart l’un
de l’autre quand l’alimentation est branchée. Couper l’alimentation avant de faire
l’installation électrique.
ATTENTION:
• Always use a power supply supplied and or specified by Extron. Use of an
unauthorized power supply voids all regulatory compliance certification and may
cause damage to the supply and the end product.
• Utilisez toujours une source d’alimentation fournie ou recommandée par Extron.
L’utilisation d’une source d’alimentation non autorisée annule toute conformité
réglementaire et peut endommager la source d’alimentation ainsi que le produit
final.
• If not provided with a power supply, this product is intended to be supplied by a
power source marked “Class 2” or “LPS” and rated at 12 VDC and a minimum of
1.5 A.
• Si ce produit ne dispose pas de sa propre source d’alimentation électrique, il doit
être alimenté par une source d’alimentation de classe 2 ou LPS et paramétré à 12
V et 1.5 A minimum.
• The installation must always be in accordance with the applicable provisions of
National Electrical Code ANSI/NFPA 70, article 725 and the Canadian Electrical
Code part 1, section 16. The power supply shall not be permanently fixed to
building structure or similar structure.
• Cette installation doit toujours être en accord avec les mesures qui s’applique
au National Electrical Code ANSI/NFPA70, article725, et au Canadian Electrical
Code, partie1, section16. La source d’alimentation ne devra pas être fixée de
façon permanente à une structure de bâtiment ou à une structure similaire.

SW HD 4K PLUS Series • Installation 8
ATTENTION:
• Power supply voltage polarity is critical. Incorrect voltage polarity can damage the
power supply and the unit. The ridges on the side of the cord (see figure5) identify
the power cord negative lead.
• La polarité de la source d’alimentation est primordiale. Une polarité incorrecte
pourrait endommager la source d’alimentation et l’unité. Les stries sur le côté du
cordon permettent de repérer le pôle négatif du cordon d’alimentation.
• To verify the polarity before connection, plug in the power supply with no load and
check the output with a voltmeter.
• Pour vérifier la polarité avant la connexion, brancher l’alimentation hors charge et
mesurer sa sortie avec un voltmètre.
• The length of the exposed (stripped) copper wires is important.
The ideal length is 3/16 inch (5 mm). Longer bare wires can short together. Shorter
wires are not as secure in the connectors and could be pulled out.
• La longueur des câbles exposés est primordiale lorsque l’on entreprend de les
dénuder. La longueur idéale est de 5mm (3/16inches). S’ils sont un peu plus
longs, les câbles exposés pourraient se toucher et provoquer un court circuit. S’ils
sont un peu plus courts, ils pourraient sortir, même s’ils sont attachés par les vis
captives.
• Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling
spaces or in wall cavities.
• Sauf mention contraire, les adaptateurs AC/DC ne sont pas appropriés pour une
utilisation dans les espaces d’aération ou dans les cavités murales.
1. Cut the DC output cord to the length needed.
2. Strip the jacket to expose 3/16 inches (5 mm) of the conductors.
3. Slide the leads into the supplied 2-pole captive screw plug, and use a small screwdriver
to secure them.
4. To verify the power cord polarity before connecting the plug, connect the power supply
with no load and check the output with a voltmeter.
5. Use the supplied tie wrap to strap the power cord to the extended tail of the connector.

Wiring the CONTACT/TALLY Connectors
To enable input switching via contact closure, connect a push-button contact closure device
to a Contact connector (see figures 2 and 3, G, on page 5).
To identify the currently selected input when the front panel buttons are not visible, connect
a device such as an LED to the CONTACT/TALLY connector (G) and to the +V connector
(D). When the input you are using is selected, the corresponding Tally Out pin shorts to
ground, activating the connected indicator.
SW2 and SW4 CONTACT/TALLY Connectors
The CONTACT/TALLY panel on the SW2 and SW4 models contains one (SW2) or two (SW4)
female captive screw connectors, each with two pairs of pins labeled Cand T.

Figure 7. Contact/Tally and Remote RS‑232 Ports on SW2 and SW4 Models
Each pin pair is labeled with the number of the HDMI input associated with it. (For example,
in figure 7, 1, the number 1indicates the contact and tally pins for input 1.) Wire devices to
these connectors as follows:
1. SW2 — Wire and connect the provided 5-pole plug to the 5-pole CONTACT/TALLY
captive screw connector on the rear panel.
SW4 — Wire and connect the provided 5-pole plug to the CONTACT/TALLY
connector on the left (containing pin pairs 1 and 2), and wire and connect the provided
4-pole plug to the connector on the right (pin pairs 3 and 4).
2. Connect contact input and tally output devices to the pin pair for each input:
• To enable input switching via contact closure, connect a push-button contact
closure input device to pin C(2) and to the G(ground) pin (5) of the 3-pole
RS-232 connector.
• To identify the currently selected input when the front panel buttons are not visible,
connect an indicator device, such as an LED, to tally output pin Tof the same pair
of pins (3).
When the input you are using is selected, the corresponding tally out pin shorts to
ground, which activates the connected indicator.
3. Insert the power wires for the contact indicator devices into the +V connector (4).
4. Press the button on the contact closure device to switch the connected input to the
output.

SW6 and SW8 CONTACT IN/TALLY OUT Connectors
The REMOTE panel on the SW6 and SW8 models contains six (SW6) or eight (SW8) 3-pole
captive screw connectors, each with three pins labeled C, G, and T, for contact closure
and tally indicator devices. The panel also contains a 3-pole captive screw connector with
three +V pins that provide power to the contact indicator devices connected to the tally (T)
ports. (The REMOTE panel also contains the RS-232 connector, which is not used for contact
closure on these models.)

LockIt HDMI Cable Lacing Bracket Installation
The Extron LockIt lacing bracket secures a
standard HDMI cable to most HDMI devices.
NOTE: The HDMI device must have an
HDMI connection mounting screw for
this bracket to be used.
To securely fasten an HDMI cable to a device:
1. Plug the HDMI cable into the panel
connection.
2. Loosen the HDMI connection mounting screw
from the panel enough to allow the LockIt
lacing bracket to be placed over it. The screw
does not have to be removed.
3. Place the LockIt lacing bracket on the screw
and against the HDMI connector, then tighten
the screw to secure the bracket.
4. Loosely place the included tie wrap around
the HDMI connector and the LockIt lacing
bracket as shown.
5. While holding the connector securely
against the lacing bracket, tighten the tie
wrap, then remove any excess length.
ATTENTION:
• Do not overtighten the HDMI connection mounting screw. The shield to which
it is fastened is very thin and can easily be stripped.
• Ne serrez pas trop la vis de montage du connecteur HDMI. Le blindage auquel
elle est attachée est très fin et peut facilement être dénudé.
