matériel contient des instructions importantes concernant l’exploitation et la
maintenance (réparation).
Ce symbole sert à avertir l’utilisateur de la présence dans le boîtier de l’appareil de
tensions dangereuses non isolées posant des risques d’électrocution.
Attention
Lire les instructions• Prendre connaissance de toutes les consignes de sécurité et d’exploitation avant
d’utiliser le matériel.
Conserver les instructions• Ranger les consignes de sécurité afin de pouvoir les consulter à l’avenir.
Respecter les avertissements • Observer tous les avertissements et consignes marqués sur le matériel ou
présentés dans la documentation utilisateur.
Eviter les pièces de fixation • Ne pas utiliser de pièces de fixation ni d’outils non recommandés par le
fabricant du matériel car cela risquerait de poser certains dangers.
Warning
Power sources • This equipment should be operated only from the power source indicated on the
product. This equipment is intended to be used with a main power system with a grounded
(neutral) conductor. The third (grounding) pin is a safety feature, do not attempt to bypass or
disable it.
Power disconnection • To remove power from the equipment safely, remove all power cords from
the rear of the equipment, or the desktop power module (if detachable), or from the power
source receptacle (wall plug).
Power cord protection • Power cords should be routed so that they are not likely to be stepped on or
pinched by items placed upon or against them.
Servicing • Refer all servicing to qualified service personnel. There are no user-serviceable parts
inside. To prevent the risk of shock, do not attempt to service this equipment yourself because
opening or removing covers may expose you to dangerous voltage or other hazards.
Slots and openings • If the equipment has slots or holes in the enclosure, these are provided to
prevent overheating of sensitive components inside. These openings must never be blocked by
other objects.
Lithium battery • There is a danger of explosion if battery is incorrectly replaced. Replace it only
with the same or equivalent type recommended by the manufacturer. Dispose of used batteries
according to the manufacturer's instructions.
Avertissement
Alimentations• Ne faire fonctionner ce matériel qu’avec la source d’alimentation indiquée sur
l’appareil. Ce matériel doit être utilisé avec une alimentation principale comportant un fil de
terre (neutre). Le troisième contact (de mise à la terre) constitue un dispositif de sécurité :

Installation
Step 1
Turn off power to the switcher and all other
devices that will be connected.
Step 2
Mount the switcher in a rack, or install the four
rubber feet (included) and place the switcher on
a desktop.
Step 3
Attach VGA, S-video, or composite video input
devices to the designated groups on the
switcher, using appropriate connectors (see
illustration on next page).
Step 4
Connect up to three VGA, S-video, or composite
video output devices to the switcher, using the
appropriate connections.
Step 5
Attach audio inputs to the switcher with RCA
connectors (see illustration at right).
Step 6
Connect up to four audio output devices to the
switcher (one to each group and one to Master
Audio) using 5-pole captive screw connectors
(see illustration at right).
Pay extra attention to the Right channel
audio wiring. The “+” and “-” layout is
different than most other Extron products.
Step 7
Set the Mic “+24V Phantom Power” switch to
match the microphone type, then plug in the
microphone.

If the switcher is to be connected to a computer
or host controller for remote control, connect the
host’s RS-232 cable to a 5-pole captive screw
connector and to the serial port on the switcher
(see wiring illustration at right and the serial
port pinout table in chapter 5, Remote Control).
Configure the serial port for the type of control
you will be using (RS-232, RS-422, or RS-485) by
setting the DIP switch adjacent to the port (see
illustration at right ).

Introduction
About the SWP123 Presentation Switcher
The Extron SWP123 is a presentation switcher featuring three independent
audio/video (A/V) switchers and a master audio switcher in one enclosure.
They include a 4 x 1 composite video/stereo audio switcher, a 4 x 1 S-video/
stereo audio switcher, a 4 x 1 VGA/audio switcher, and a 3 x 1 Master Audio
switcher. The SWP123 accepts microphone input and mixes the microphone
signal with the main audio in “talk over” mode. The SWP123 also features a
built-in transcoder loop function and an RS-232/RS-422/RS-485 control port.
“SWP123” and “switcher” are used interchangeably in this manual to refer to
the SWP123 Presentation Switcher.

Mounting the Switcher
The SWP123 is housed in rack-mountable, 2U high, 19" wide metal enclosures.
The switcher may also be placed on a table or desk top.
Tabletop use
The switcher comes with rubber feet for tabletop use. Attach a self-adhesive rubber
foot to each corner of the bottom of the unit if you intend to use it on a tabletop.
If you intend to mount the switcher in a rack, do not install the rubber feet.
Rack mounting
Rack mount the switcher as follows:
1. If the rubber feet are attached, remove them.
2. Insert the switcher into the rack, aligning the holes in the mounting
bracket with those of the rack.
3. Secure the switcher to the rack using the supplied machine screws.

Connecting the SWP123 Switcher
The SWP123 Presentation Switcher can be connected to as many as 12 input
devices simultaneously and to up to 3 outputs simultaneously. Follow the steps
below and see the installation example in figure 2-3.
If the switcher is to be mounted, see Mounting the Switcher, earlier in this
1
chapter.
Turn off power to the switcher and all other devices that will be connected.
2
Using inputs 1, 2, 3, and 4 of the VGA, S-video, and Video (composite)
3
groups, attach up to 12 video input devices to the switcher.
Connect output display devices to the switcher using VGA, S-video, or
4
Composite Video outputs.
Connect up to 12 stereo audio sources to audio inputs 1, 2, 3, and 4 of the
5
VGA, S-video, or Composite Video audio groups. See Audio input and output
later in this chapter.
If using a computer or host controller for remote control, connect the host’s
6
RS-232 cable to the 3.8 mm, 5-pole captive screw serial port (Serial Port A) of
the switcher. For an RS-232/RS-422/RS-485 pinout table and DIP switch
settings, see Remote Control Port (RS-232/RS-422/RS-485) in chapter 5.
Power up the input and output devices, then connect power to the
7
switcher.
