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.  
SWP123 Switcher Features  
Bandwidth — Bandwidth for the VGA switcher is 450 MHz (-3dB), allowing the  
switcher to switch everything from NTSC video to high-resolution computer  
displays.  
Multiple video inputs — Twelve inputs can include four composite video (NTSC,  
PAL, or SECAM) on BNC female connectors, four VGA (or SVGA, UXGA,  
RGBHV, RGBS, RGsB, or RsGsBs) on 15-pin HD female connectors, and four  
S-video (NTSC, PAL, or SECAM) on 4-pin mini DIN female connectors.  
Multiple video outputs — Three outputs for simultaneous (in Separate mode), and  
one at a time (in Single mode) display on VGA, S-video, or composite video.  
Multiple audio inputs — Twelve line level unbalanced stereo inputs can include  
four to the VGA group, four to the S-video group, and four to the composite  
video group. All audio inputs are on female RCA connectors.  
Multiple audio outputs — One output for each group (VGA, S-video, and  
composite video), plus Master Audio. All audio outputs are balanced or  
unbalanced on 3.8 mm, 5-pin captive screw connectors.  
Master audio switcher — A 3 x 1 stereo audio switching system allows the audio  
input of any video group to be selected for Master Audio output, with  
volume and mute control.  
Individual input audio attenuation adjustments — To balance each audio input  
Master-Audio-Follow-Video switching — When enabled, the Master Audio  
automatically follows the last input selected, regardless of group (VGA,  
S-video, or composite video).  
This feature is disabled as a factory default. You must enable the feature  
using an RS-232 serial command or the ICS100 Control Software.  
Decoder loop function — Converts all composite video signals to S-video using  
an optional external composite video to S-video decoder.  
This feature is disabled as a factory default. You must enable the feature using  
an RS-232 serial command or the ICS100 Control Software.  
Microphone input — Built-in microphone amplifier and Microphone Talk Over  
button, with adjustable talk-over threshold control and microphone  
volume level control  
+24V Phantom power — For condenser microphones  
Front panel control disable — Locks out all front panel functions except input  
selection. When the front panel controls are disabled, all controls are still  
available through RS-232, RS-422, or RS-485 commands.

RS-232/RS-422/RS-485 remote control — Allows third-party remote control of  
switchers using Serial Control Protocol or ICS100 Control Software.  
Rack-mountable — The 2U high, full rack wide, metal enclosure is rack-mountable.  
IR control — Enables user to select inputs/outputs and adjust volume using  
optional CTL 120-3 IR Remote Control.  
Internal Universal power supply — Operates with AC power from 100-240 VAC,  
50/60 Hz for worldwide compatibility.

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.

Front Panel Operation  
The functions of the front panel controls are described in the following sections.  
Selecting A/V inputs to output  
There are four input selection groups on the front panel: VGA/Audio, S-video/  
Audio, Composite Video/Audio, and Master Audio. These groups correspond to  
the four independent switchers (three A/V and one audio only) in the SWP 123  
Presentation Switcher.  
Use the four input select buttons in each A/V group to route a video signal to the  
output for each group. When you press an input select button, the green LED  
indicator on top of the button lights, indicating which input is linked to the  
output for that group. To select a different input for that group, press a different  
button in the same group.  
The outputs of all three A/V groups are always active within the group. The  
audio output from any group (or the microphone) may be routed to the Master  
Audio switcher for output. See the Master Audio functions section (below) for more  
details.  
There are two switcher modes available for the SWP123: Separate switcher mode  
and Single switcher mode. The default is Separate switcher mode.  
Separate switcher mode  
In this mode, all three A/V groups operate independently from each other, and  
all three outputs (audio and video) are active.  
Single switcher mode  
This mode can be turned on/off only via RS-232. In this mode, all three A/V  
groups operate as a combined 12 x 1 switcher (12 inputs and one output). Only  
the output (audio and video) of the selected A/V group is active, while the  
remaining two unselected A/V group outputs are muted. This design feature  
enables the autoswitching feature of the output device (scaler, etc.).  
Blanking the output from a group  
Each A/V group has a blank button. To blank the video output for a group, press  
the Blank button for the group. The LED above the button lights, indicating that  
blanking is active.

Power switch on the back panel of the switcher to On.  
Decoder Loop Function  
For data projectors, plasma displays, and other displays on which the composite  
video and S-video inputs do not work independently, the SWP123 is equipped  
with a decoder loop function that converts all composite video signals to S-video.  
This is accomplished by using an external Extron YCS Transcoder or a VYC  
100N/P composite video to S-video decoder. Once the decoder loop is  
configured and programmed, the following occurs when you select a composite  
video input:  
• The switcher automatically selects Input 4 in the S-video A/V group to enable  
the loop.  
• The Extron YCS Transcoder or VYC 100N/P composite video to S-video  
decoder converts all composite video signals coming through the switcher  
to S-video.  
Wiring the decoder loop  
1.  
2.  
3.  
4.  
Connect the output of the Composite Video A/V group to the composite  
input of the transcoder or decoder.  
Connect the S-video output of the transcoder or decoder to S-video input 4  
of the SWP switcher.  
Connect the S-video output of the SWP switcher to the S-video input of the  
display device.  
Activate the decoder loop using the correct RS-232 serial command (see  
chapter 5) or the ICS100 Control Software (see chapter 4).

Commands and responses for programming the SWP123 Switcher from a  
host system connected to the RS-232/RS-422/RS-485 port are listed on the  
following pages.  
DIP switch settings  
Use the DIP switch bank in the back of the SWP123 switcher to  
configure the serial ports to operate as an RS-232 (factory  
default) or RS-422/RS-485 interface. DIP switch settings  
change according to the standard used. Configure the DIP  
switch according to your requirements, based on the table  
below.  
RS-232  
RS-422/485  
Termination resistors should be turned on only when the switcher is  
operating in RS-422/RS-485 mode, and then only for the first and last units  
on a long serial line. The default switch settings are all OFF. In half-duplex  
mode, turn on only one of the termination resistors, as they are connected  
together by the cable.

Host-to-Switcher Communications  
The SWP123 switcher accepts Serial Control Protocol commands through  
the RS-232/RS-422/RS-485 port. These commands consist of one or more  
characters per command field. They require a beginning character ([) and an  
ending character (]).  
This unit does not work with standard Extron SIS commands.  
Using the command tables  
The command table is shown on the following pages. Lowercase  
characters are acceptable in the command field only where indicated.  
Command and response examples are shown throughout the command  
table.  
Addressing commands  
In RS-232 mode, there is no need to assign an address to the switcher;  
however, if you are using RS-422 or RS-485 mode with several devices  
connected in parallel to a single serial port, you must assign an address  
for each unit.  
The factory default for the SWP123 Switcher is no address. If you want  
addressing, you must assign an address from 01 to 98. Address 00 is a  
broadcast address, and all connected units perform the action commanded  
(no responses is sent). Address 99 is reserved for future products.  
Once an address has been assigned to a unit [ADDRxx] the unit does not  
accept or respond to commands unless the commands are sent to the unit’s  
address [CCxx]. The unit accepts all commands issued to the specified  
address and sends responses.  
Command  
Description  
Assign address  
[ADDRxx]  
Assigns an address from 01 to 98 to the unit. Address 00 is a

Remote Control from a Network  
You can control the SWP123 switcher from a remote location across a Local Area  
Network (LAN), a Wide Area Network (WAN), or over the Internet.  
This remote network control is available in a client-server environment, where  
the PC attached to the switcher is called the server, and the PC that needs to  
control the device from another location is called the client.  
Enabling remote control of the switcher over a network  
Both the user operating the client (remote PC) and the user operating the server  
(local PC) must install the ICS100 Control Software program onto their respective  
PCs. See chapter 4, Windows-Based Control Program, for information on installing  
the software. The following sections describe how to configure the server and  
client PCs.  
SWP123 Presentation Switcher • Remote Control

Download from Www.Somanuals.com. All Manuals Search And Download.  
Configuring the server (local) PC  
1.  
Attach the switcher to the server PC with a serial cable from the PC’s serial  
port to the switcher’s serial port. For information on wiring the cable, see  
Remote Control Port (RS-232/RS-422/RS-485) earlier in this chapter.  
2.  
Click the Windows Start button, then select Programs, then Extron  
Electronics, then ICS100, then Serial Server. The Extron Server Software (the  
server) launches, and the Serial Port Server window opens.  
Figure 5-1 — ICS100 Serial Port Server window  
3.  
Make sure the Local IP, Port, Client IP, and Connection Status information is  
correct (you may need to check with your Network Administrator or IT  
group for this information). If the client PC is connected to the server, a  
Client IP address is displayed and the Connection Status shows green (red  
if not connected).  
4.  
5.  
The Extron Serial Server “listens” for the client PC on TCP/IP port 2001 (the  
factory default). If that port is already in use, you may change the number of  
the port (open the ICS100 Control Software Help file for instructions).  
When the server has been connected and configured correctly, you can  
configure the client to connect to the server (check with your Network  
Administrator to secure log-on rights to the server).  
Configuring the client (remote) PC:  
1.  
Install the ICS100 Control Software program. See chapter 4, Windows-Based  
Control Program, for information on installing the software.  
2.  
From the Windows Start pop-up menu, select Programs, then Extron  
Electronics, then ICS100. The ICS100 Control Software (the “client”)  
launches.  
3.  
Open a connection to the server as follows:  
a. In the ICS100 Control Software, select Network from the  
Communications menu. The Server Connection window opens.

b. Enter the IP Address and Port number of the server PC.  
c. Click OK. The connection is visible in the main window.  
d. Click OK again. The client PC can now be used to control the switcher.  
Adjusting response time  
The user operating the client PC may want to adjust the time out interval. The  
time out interval is the number of seconds that the client waits before  
communicating with the server.  
To adjust the response time:  
1.  
2.  
From the Communications menu, select Response Time Out.  
Select the appropriate time out interval for your network (4–12 seconds).  
Selecting a longer interval does not slow down client-server communication.  
Stopping communication  
The connection between the client PC and the server PC may be closed at any  
time from either PC. To stop communications:  
From the server PC—In the Extron Server Software, from the Server menu, select  
Close Connection.  
From the client PC—In the ICS100, from the Communications menu, select Close  
Connection.

Reference Information  
Updating the Firmware  
Firmware is programming that is inserted into programmable read-only memory  
on a programmable ROM chip in your switcher, thus becoming a permanent part  
of it. Firmware controls many of the features of your switcher. Firmware is  
created, tested, and improved like software and, like software, updates are made  
available periodically. When firmware updates are available, they can be  
downloaded from the Extron Web site (www.extron.com) and, using a special  
user interface, installed in the programmable read-only memory in your switcher.  
Updating the firmware requires the installation of the Windows-based ICS100  
Control Software. For information on installing the ICS100 software, see chapter 4,  
Windows-Based Control Program.  
To update the firmware:  
1.  
When you download the firmware update, save the file in the ICS100  
subdirectory so the file can be found and used when required.  
2.  
Click the Windows Start button, then select Programs, then Extron  
Electronics, the ICS100, then Boot Loader. The Boot Loader launches and  
the Boot Loader window opens.  
Figure B-1 — Boot Loader window  
3.  
4.  
Click the Load Buffer button. An Open window appears.  
Find and double-click the firmware update (hex) file that was previously  
saved in the ICS100 subdirectory. The file loads into the buffer.  
5.  
When you are prompted with the Finish Loading Buffer message, click the  
Burn Flash button to download the firmware to the switcher.
