Introduction
Although each EXTRON System 8/10 PLUS switcher has been factory preset for the
requested projector brand configuration, it can easily be changed to make your
system switcher compatible with any projector brand you choose.
This manual has been carefully written in an effort to provide you with the
detailed information that you need to connect your System 8/10 PLUS switcher to
most projectors available in today’s market. It covers both the System 8 PLUS
and the System 10 PLUS, however, since the only difference between these two
switchers is the number of inputs, they will be referred to as “System 8/10 PLUS”.

Introduction to System 8/10 PLUS
Features
The system switcher can be controlled by the front panel switches, through its
manual remote connector (using EXTRON or third-party remote control devices), or
from a Host through an RS-232 connector. To address large installations with
more than 10 inputs, the switchers can be looped for a total of up to 154 inputs
(17 switchers). Features like Video Loop Back (VLB) make this switcher
adaptable to most application requirements.

Introduction to System 8/10 PLUS
Features
Description of Features
Outputs — Because switching is direct, the output will always have the same
format as the selected input. Separate output connectors are provided for RGBS,
Composite Video, S-Video, and Audio.
Video Loop Back (VLB) — This feature allows the switcher to integrate with either
RGB decoders or scan doublers. With VLB, a Composite or S-Video output is
routed from the switcher output through a decoder or scan doubler and then
back into System 8/10 PLUS switcher. This means that one decoder or scan
doubler can be used for all the video inputs instead of needing one unit for each
video source.
Triple-Action Switching™ (RGB delay) — This prevents image scrambling during
switching time. When an input is selected, Triple-Action Switching® will:
1. Drop the RGB signals.
2. Wait 150 ms and then switch to the new sync signal.
3. Wait for the time delay set by the user (0.0 - 7.5 seconds) and then switch to
the new RGB signals. (During this time the projector is setting up to match the
new sync.)
300 MHz Bandwidth — The wide bandwidth allows signals to be passed without
loss of resolution. This is extremely important when using high resolution
computer workstations.
Switcher Control — Each channel of the switcher can be controlled in any one of
the following ways:
• Front Panel Buttons. Lighted push buttons can be labeled for each input source.
• Remote Control Connector. Contact closure remote control connector
for hard-wired remote control with Tally indication.
• RS-232 Control Connector. Provides for computer control of switcher
or use of third-party remote control system.
• Projector Infrared Remote. Projector IR remote can control the switcher via
the projector. For some projectors, you may use the projector's remote to
control Extron system switchers. Note: not all projector’s have this capability.
• IR-30 Infrared Remote Control. The IR-30 upgrade will allow you control the
System 8/10 PLUS through the switcher’s IR receiver.
Display Power Switch — The Display Power switch controls projector power. This
is essential for ceiling-mounted projectors.
Video Mute Switch — This switch blanks the video picture without turning off the
projector power.
Balanced or Unbalanced Audio — All audio inputs and outputs use 5 mm Phoenix
brand six-terminal connectors. This allows for connection of balanced or
unbalanced line audio.
Audio Breakaway (RS-232 control only) — Audio and video may be selected from
separate input channels.
Easy System Expansion — Up to 17 switchers can be looped (daisy chained)
together to provide up to 154 inputs when using a combination of System 8 or
System 10 switchers.
Power — The System 8/10 PLUS switchers have an internal, auto-switching (90 260 VAC) power supply. The System 8/10 PLUS switchers are UL approved.
Rear Panel LED Indicators — Rear panel LEDs indicate which input has been
selected and which outputs are active.
Rack Mount — The 3U x 19" System 8/10 PLUS enclosure is ready for rack
mounting.

The following list refers to each input channel (left diagram):
1. Input LEDs: Green LED indicator (1-8 or 1-10) lights to indicate selected input.
2. Audio Level: An audio level attenuator is provided for each input channel (1-8 or
1-10) to normalize audio output levels. The attenuators can only decrease (not
increase) audio levels.
The following are in the output section (right diagram below):
3. NORM/VLB Switch: Set this switch to “VLB” to select Video Loop Back mode
when using composite-to-RGB decoder or scan doubler (e.g., Extron Andora).
Set switch to “Norm” for normal operation. Refer to the discussion of Video Loop
Back mode later in this chapter.
4. Output LEDs: Green LED indicator (3 locations) lights to indicate which type of
output is selected. (RGBHV, Composite, or S-Video).
5. S-Video/S-VHS Switches: Used only when setting up an input. (1-8 or 1-10)
Separate switch for each input
channel to select input/output type
(RGBHV, Composite, or S-Video).
6. NTSC/PAL Switches: Used only
when setting up an input. (1-8 or
1-10) Separate switch for each input
channel to select input/output type
(RGBHV, Composite, or S-Video).
7. Address Switches: Used only
when setting up a master/slave
configuration. Setting determines
binary address of slave switcher.
See Chapter 5 for looping two or
more switchers.
8. Master LED: Lights when this
switcher is configured as the Master
in a loop, or when the switcher is
operating in a stand-alone
configuration.
Details on the function of each panel
section is described on the following pages.
DIP Switch Types
There are different types of DIP switches, some “slide” and some “rock”. Your
System 8/10 PLUS could have either type DIP switch. Although they operate
differently and are labeled differently, they are simply On (switch closed) or Off
(switch open). In the example diagram on the left, with the slide-type DIP switch,
move the slide up to set the switch On (closed). With the rocker-type DIP switch
shown in this example, press the top rocker down to set the switch On (closed).
The two example switches shown here are set up for the same configuration.
Throughout this manual, you may see either type of switch, however, the switch
positions will be the same regardless of the switch type.

Rear Panel Connections
Input Section
Each input channel of the System 8/10 PLUS has the following:
• A set of five BNC connectors mounted vertically.
• A six-pin audio connector located below each set of BNC connectors.
• A green LED indicator above each set of BNC connectors ( ) lights to
indicate that this input is selected. (Only one input can be selected at a time.)
With this combination of input connectors, the System 8/10 PLUS can accept any
type of video input format (NTSC/PAL, S-Video/S-VHS or RGBS). Also, each
input can have stereo audio. The System 8/10 PLUS handles signals according to
how they are connected to the input, as well as how the configuration DIP
switches are set. Each type of setup is explained in detail later in this chapter.
When the System 8/10 PLUS is used to switch different types of signals, the
output signal will have the same format as the selected input. That is, RGB and
Sync (composite or separate H&V) will exit through the RGB and Sync output.
Likewise, NTSC and PAL video signals go to the Composite Video output.
Therefore, if multiple signal types are used in the same switcher, the same
multiple outputs must be used by the projector or display monitor. Some displays
receive all signals on the RGBHV port when under switcher control (see the
appropriate connection diagram in Chapter 3 for your projector).
Output Section
The System 8/10 PLUS has three sets of
output connectors, one for each video
format: RGBS, S-Video/S-VHS (Y/C) and
NTSC/PAL (composite video). There is a
green LED to identify which output is active,
as determined by which type of input is
selected. There is also a 6-pin audio output
connector at the bottom, as well as left and
right audio BNC outputs.
_____ If audio comes in on BNC connectors, it
goes out the BNC connectors; if it comes in
on the 9-pin Phoenix® connector, it goes out
the 9-pin Phoenix connector.
Video Loop Back (VLB)
When using Extron’s Sentosa, Lancia, a third-party scan converter or a
Composite/S-Video-to-RGB decoder, the System 8/10 PLUS allows the use of a
single scan-doubler or decoder with multiple switcher inputs to be looped back
through the System 8/10 PLUS and then out again as RGB Sync together with all
other RGB Sync inputs. These video configurations are described in detail later
in this chapter.
Power
Although the power cord connector is on the back panel, the fuse is actually on
the power supply inside the cabinet. System 8/10 PLUS switchers have power
supplies that accept 90-260 VAC, 50/60 Hz line power. No power configuration is
required. The fuse rating is 250 VAC, 2 Amp fast-blow.

Input Configurations
Each System 8/10 PLUS switcher input can be configured for any of the following
RGB connections:
•
•
•
•
•
RGB - Red, Green/sync, Blue (3 cables)
RGBS - Red, Green, Blue, and Composite Sync (4 cables)
RGBHV - Red, Green, Blue and Separate H & V Sync (5 cables)
Composite (NTSC/PAL) - Using the G connector (1 cable)
S-Video/S-VHS - Using the G connector for Y and H/HV connector for C
(2 cables)
All video inputs to the System 8/10 PLUS use BNC connectors. Many types of
video devices (VCR, laserdisc players, some computers, etc.) do not have BNC
video output connectors. For this reason, an adapter may be required to connect
the device output to the BNC input of the System 8/10 PLUS. (See parts list in
Appendix B.) With the proper adapter, the RGBS signal can be connected
directly to the R, G, B, H and V inputs of the switcher. If the RGB signal is
carrying the sync on the green channel, connect the three RGB cables to the
switcher without using the sync channels. Audio connections may be used with
any of these video inputs.
Input Switches and Output LEDs
When configuring an input, the video mode must be set up in the DIP switches
located above the output connectors. There are two banks of eight (or ten)
switches. The left bank is for S-Video and the right bank is for Composite
(NTSC/PAL) video. One switch in each bank is assigned to an input channel
number. For example, input #1 uses the leftmost switch at each bank. For the
video mode shown on this page, DIP switch #1 of each switch bank must be in
the RGBS position, which is in the down position.
The System 8/10 PLUS switchers are shipped with all DIP switches in the down
position (RGBS inputs). For composite video input, change the NTSC/PAL DIP
switch for that input channel to the up position. For S-Video or S-VHS input,
change the S-Video/S-VHS DIP for that input channel to the up position.
There is an Output LED next to each set of output connectors. When an input is
selected, the Output LED indicates the format for which that input has been
configured. This also informs the user which output should be used.
_____ These output LEDs also serve as a configuration check. Also, for displays which
have all of their signals (including S-video and Video) on the RGBHV port, both
the RGB LED and either the S-video or Video LED will light simultaneously.
1. For example, if input #1 is using RGBS, and DIP switch #1 of the S-Video
bank was accidently switched “up”, then the S-Video output LED will be lit,
instead of the RGBS LED. This informs the user of an improper setting.
2. The only conditions for which two output LEDs can be lit at the same time is
when the System 8/10 PLUS is used in the Video Loopback mode.
3. Under normal conditions, one of the output LEDs should be lit.
4. All three output LEDs should never be lit at the same time.
5. If no LEDs are lit, check for proper switch settings.
The following pages show examples of the three possible input configurations.

Video Output
Rear Panel Connections
Video Output Connections
The System 8/10 PLUS has three sets of BNC output connectors (RGBHV,
Composite, and S-Video). Which output connectors are active depends upon
which type of input is selected. These connectors provide outputs from the
System 8/10 PLUS to the video projector or display monitor. When an input
channel is selected, the corresponding LED lights to show the format of the
selected video and which output is being used.
Only one output can be active at any given moment, unless the VLB (Video Loop
Back) feature is being used.
All output signals have the same format as the selected input. They are switched
to the output unaltered. That is: RGBHV input signals are RGBHV output signals,
composite video input signals are composite output signals, and S-Video input
signals are S-Video output signals. Thus, if multiple input signal types are used,
such as audio on the R and B inputs, the same multiple output signals will be on
the corresponding output to the projector or display monitor.
1. LED Output Indicators (See in figure above.)
An LED lights to identify which of the three outputs is currently being used.
2. RGB Output Connections ( )
Attach BNC cables to outputs labeled “R”, “G”, “B”, “H/HV”, and “V”.
3. Composite Video Output Connections ( )
Attach a single BNC cable to the output marked “Video”.
4. S-Video Output Connections ( )
Attach the Y (luminance) cable to the BNC connector marked “Y” in the S-Video
section and the C (chroma) cable to the BNC connector marked “C”.
5. If the audio for the selected channel uses the Phoenix® input connector, then the
audio output must use the Phoenix output connector ( ). See next page.

The System 8/10 PLUS can accept audio from two different sets of input
connectors. Left and right audio can use the R and B BNC connectors shown to
the left (labeled R Audio and L Audio). Audio can also use the 6-pin Phoenix®
brand of captive screw connector shown at the bottom of each input and output.
Audio connections can be made using the Phoenix
terminals in the following ways:

when using Composite Video or S-Video sources. When using the BNC input
ports for audio, any unselected audio port will be terminated at 75 ohms. Verify
that this termination will not damage the output.
An audio level attenuator is located to the right of each bottom BNC input
channel connector. The attenuators are used to adjust only the audio levels
going to the Phoenix connector output, and not those going to the BNC outputs.
Because attenuators can only decrease (not increase) the audio levels, initial
adjustments should be made with the attenuators set to the maximum
(clockwise) position.
The captive connectors are located on the rear panel, just below the BNC
connectors, and are labeled “R” (right) and “L” (left) for each channel. When
wiring these Phoenix connectors and inserting them into the System 8/10 PLUS
switcher, remember that the screw heads must face downward. Use the
following diagrams to wire the connectors for your audio inputs and outputs.
_______ Because all switching is one-to-one, the audio output must use the same
connector type(s) as the input (Phoenix to Phoenix or R/L Audio to R/L Audio).
600 ohm resistors, .25 W
_____ Nine audio connectors are shipped with each System 8 PLUS and eleven with
each System 10 PLUS. If more are needed, use Phoenix® audio connectors,

Composite Video (NTSC/PAL) Input Connections
NTSC (National Television Standards Committee) and PAL (Phase Alternate
Line) composite video signals use a single coax cable. They may or may not
have separate audio.
See the illustration below to connect a composite video source to the input of a
System 8/10 PLUS. If the source has stereo audio, it can be connected either of
two ways. The solid line shows the use of a Phoenix® audio connector that has
six (6) conductors. Details on audio connections are given on page 2-6. The
second method of audio input connection is shown by dashed lines, and is also
explained on page 2-6.
Input Selection Switches
To complete the Composite Video configuration, the DIP switch for the input
number being configured must be in the up position. These switches are on the
right side of the rear panel. The switch for the example (input #4) is shown in the
NTSC/PAL position. The S-Video switch for this channel (input #4) must be in
the down position.
When the System 8/10 PLUS selects this input, the LED next to the output
marked “Video” will light. See arrow in illustration below.
_______ If audio input uses the Phoenix connector, the output must also use the Phoenix
connector. If the input uses BNC connectors, the output must also use BNC
connectors.

S-Video Input
Rear Panel Connections
S-Video Input Connections
S-Video or S-VHS is typically an output from the AV source on a 4-pin miniature
DIN type connector which must be converted to 2 BNC type connectors – one for
chrominance (C) and the other for luminance (Y) - [Extron adapter cable 26-35301]. S-Video input to the System 8/10 PLUS is made by connecting the chroma
(C) to the H/HV/C input connector and the luminance (Y) to the G/Video/Y input
connector. Audio inputs from the AV source are made to either the R & L inputs
of the System 8/10 PLUS or to the R/R-Audio and B/L-Audio BNC connectors.
Input Selection Switches
Each input must be configured. This is done by setting the DIP switches located
above the output connectors. There are two banks of DIP switches, each having
8 (or 10) switches. Each input channel has two switches assigned to it, one in
each bank. For example, input #3 uses the third switch at each bank. For the SVideo input shown below (S-Video signal connected to channel 3 input), the #3
DIP switch of S-Video/S-VHS bank should be in the up (Video) position and the
#3 DIP switch of the NTSC/PAL should be in the down (RGBS) position.
Place the S-Video/S-VHS switch for the input channel being configured in the
Video (up) position. The NTSC/PAL switch for this channel (input 3, in this
example) must be in the down position.
When the System 8/10 PLUS selects this input, the LED next to the output
marked “S-Video” will light. See arrow in illustration below.
_______ If audio input uses the Phoenix connector, the output must also use the Phoenix
connector. If the input uses BNC connectors, the output must also use BNC
connectors.

Video Loop Back
Rear Panel Connections
Video Loop Back (VLB)
Video Loop Back (VLB) is a special feature which allows a scan doubler (also
called “line-doubler”) or an RGB decoder to be used with the System 8/10 PLUS
switcher. With VLB enabled, any input can use an RGB decoder or a scan
doubler without recabling. This reduces the amount of equipment needed for a
system that requires the use of either of these devices.
The VLB mode is turned on and off by a toggle switch located between output
connectors on the right, rear panel of the System 8/10 PLUS. With the switch in
the NORM (up) position, the VLB mode is disabled. In the VLB (down) position,
Video Loop Back is enabled.
To configure the System 8/10 Switcher for Video Loop Back, connect the
Composite video or S-video output(s) source to a System 8/10 PLUS input.
Connect the output of the System 8/10 PLUS S-Video and/or Composite video to
the input of the decoder or line doubler. Then connect the RGBS output of the
decoder or scan doubler to the last input of the switcher. Only the last input can
be used as VLB input. That is, input #8 of the System 8 PLUS, or input #10 of the
System 10 PLUS.
_____ When connected for Video Loop Back, the number of usable inputs is reduced
by one because VLB uses the last input.
Normal Mode
The VLB switch is set to NORM and no decoder or scan doubler is connected.
When Composite and S-Video input signals are selected, they are routed directly
to the projector (or display monitor) through the normal Composite and S-Video
output connector set.
VLB Mode
Set this switch to the “VLB” position when an external decoder or scan doubler is
connected, as pictured on the following page. When a Composite or S-Video
input signal is selected, it goes through the normal Composite or S-Video output
connectors to an external (user provided) Composite-to-RGB decoder or scan
doubler. The RGBS output of the decoder or scan doubler is “looped back” to the
last input of the System 8/10 PLUS. The decoded (or scan doubled) RGBS signal
is then routed directly to the projector (or display monitor) from the System 8/10
PLUS RGBS output connectors (see diagram on the following page).
Optional Extron Products that can be used with a System 8/10 Plus in Loop Back
mode include:
• CD 400 – Quad Standard Decoder
• Lancia – NTSC & PAL Scan Doubler
• Sentosa – High Resolution Video Line-Quadrupler
60-145-01/02
60-213-01
60-229-01
VLB Restrictions
• When using the VLB mode with multiple switchers, always connect the
switchers in a Star Configuration. The VLB mode cannot be used when
switchers are connected in a Daisy-Chain configuration.
• Only the master switcher can use the VLB mode (slave switchers cannot).
• Refer to Chapter 5 for instructions on looping switchers in the Star
Configuration.
• For projectors that accept S-video and Composite video signals on their
RGBHV port, VLB can only be used when the System 8/10 PLUS is no longer
in cable saver mode (see page 3-4 for SW settings).

VLB Operation
The illustration below is an example of a decoder being used in Video Loop
Back, however, it could be any one of several types of decoders or line doublers.
When VLB is active, the System 8/10 PLUS operates as follows:
1. Composite video and S-Video sources are connected to any of the System 8/10
PLUS inputs except the last one.
2. Standard RGB inputs exit the switcher through the normal RGB output.
3. Composite Video or S-Video signals exit the switcher through their normal
Composite video or S-Video outputs and are routed to the external decoder or
scan doubler.
4. The RGBS output of the decoder or scan doubler is then “looped back” to the
last input (input #8 or #10) of the switcher, which is selected at the same time.
5. The RGBS output from the switcher goes to the projector.
This allows the System 8/10 PLUS to route only RGB signals to the display
device.

Special Features
Rear Panel Connections
Special Features
The System 8/10 PLUS has some special features, one of which is Auto Sync
Detect. Auto Sync Detect determines what type of RGB sync is being input.
Sometimes this feature must be disabled when connecting to certain projectors.
For example, if a Barco projector is powered up with no input yet present at the
switcher, the projector will not detect any sync and will default to sync on Green.
Later, if an RGB source with separate sync is connected to the System 8/10
PLUS, the Barco projector, which is still expecting sync on Green, may
experience problems dealing with this conflicting situation. However, by setting
both Input Selection DIP switches up (disabled), the switcher will disable Auto
Sync Detect which will communicate to the projector that the RGB input has
separate sync. Similarly, if Auto Sync Detect is enabled (both DIP switches
down) for an RGB input, the switcher communicates to the projector that the
RGB input has sync on Green.
Input Selection Switches
Each input must be configured. This is done by setting the DIP switches located
above the output connectors. There are two banks of DIP switches, each having
8 (or 10) switches. Each input channel has two switches assigned to it, one in
each bank. For example, input #2 uses the second switch at each bank. By
setting input #2 up in both banks, the Auto Sync Detect feature will be disabled
and the RGB sync will be defined as separate sync (as described above).

Cabling a System 8/10 PLUS in a Rack
When routing cables from one unit to another in a rack,
do NOT allow the cables to pull down on the
equipment. Use “Tie Wraps”, “Rip-Ties” or other
devices to secure the cables at some location in the
rack that is above the rear panel connectors. Loosely
hanging cables may be stepped on, resulting in
damage to cables and equipment, as well as injury to
personnel.
The illustration shows the rear view of a system rack.
The example has the cables tied to the rack above the
connections to the equipment. This allows a clear view
of the back panels and prevents the cable weight from
pulling down on the equipment.
_______ The holes in the top and bottom of the System 8/10 PLUS enclosure are for
cooling. Do NOT cover these holes. This could cause overheating of vital
components.
_______ Maximum ambient operating temperature must not exceed 104° F (40° C).
_______ The mounting rack and all equipment mounted in it must be grounded according
to national and local electrical codes.
_____ Keep power and signal cables separate (power cables on the right and signal
cables on the left.)

Extron System 8/10 PLUS switchers have bidirectional (i.e., "talk-listen"), userprogrammable communications that communicates with the displays listed
above. If projector input selection is made by the hard-wired or infrared remote
control of the display*, the System 8/10 PLUS switcher "listens" to the selection
and switches to the proper input.
When an input selection is made at the switcher (by a front panel button, hardwired remote control, RS-232 communications or IR-30), the System 8/10 PLUS
switches the projector to RGBS, S-Video, or Composite (as required) and
commands the projector to load the pre-programmed presets for that input.

Setting the System 8/10 PLUS for the Projector
Before each System 8/10 PLUS ships, it is configured for the projector type as
requested by the user. However, it can easily be reconfigured for any application.
The picture below shows the function of each switch behind the access cover on
the front panel of the System 8/10 PLUS.
______ Do not change any switch settings without following the correct procedure in this
chapter. Go to the appropriate procedure for your application.
Triple-Action Switching™ (RGB Delay Switch - RS5)
When an input is selected, the sync switches immediately. However, the picture
may be switched later (0.0 - 7.5 seconds) to prevent an unstable image while the
projector is setting up for the new sync signal. RS5 is used to set this delay.
Each position of the switch adds 0.5 seconds to the delay.

General
Controlling the System 8/10 PLUS Switchers
The System 8/10 PLUS Switchers can be controlled four ways:
1. Manual front panel controls (See next page.)
2. Manual, (contact closure) wired remote control
3. Manual infrared remote control
4. RS-232 control (from a host system)
Manual Remote Control
The Manual Remote connector can be used to select inputs by means of dry
momentary contact closures and Tally outputs to drive (user provided) remote
LEDs to indicate which of the inputs have been selected. This is described in
detail on page B-1 of the appendix.
RS-232 Control
The RS-232 Comm connector provides a serial interface for switching inputs by
means of a host computer (such as a PC) or other third party control system,
such as Crestron® or AMX®. For example, a control program in a PC could be
written in a DOS or Windows® environment. RS-232 programming is described
in Appendix A.

Front Panel Buttons and Indicators
The following Front Panel Controls are used to operate the System 8/10 PLUS.
Power indicator – Lights to indicate System 8/10 PLUS switcher input power is On.
This LED also blinks when the optional IR-30 remote receiver is detecting a
signal from the transmitter.
Display Power Button – This button is used to turn the projector ON or OFF. To
turn the projector ON, press this button down until it flashes on, then off,
(approximately two seconds) and then release the button. Some projectors take
a few seconds to initialize. For those projectors, the Display Power button will
flash to prevent any communications during the initialization period. This flashing
can last from 8 to 35 seconds. To turn OFF the projector, press and hold the
button down until it flashes off, then on (approximately two seconds). This two
second delay provides a safety factor so the projector is not turned off by
accidentally touching this button.
Display Mute Button – The Video Mute button is similar to a “Projector Mute” or
“Pause” button typically found on the projector remote control. This button mutes
(blanks) the projector display, but does not actually turn the projector off. Press
to mute the video display. The button lights to indicate Display Mute mode has
been selected and the projector display is blanked. Press the button again to
restore the video image.
RGB Mute – Pressing this button interrupts the picture (RGB) to the display device,
but not the sync. Pressing the button again restores the picture without flicker.
Audio Mute – Press to mute the audio. The button lights to indicate audio mute
mode has been selected. Press again to restore the audio. The button light then
goes out.
Input Select Buttons – Press to select video input. (System 8 has buttons 1-8 and
System 10 has 1-10.) Each button lights when its input is selected. Only one
input can be selected at one time. These buttons flash to indicate that audio only
is selected from that input (Breakaway).
Infrared Receiver – The lower left corner of the front panel has the receiver lens for
the infrared (IR System Remote) control. Although the lens is there, it will not
operate if the option is not installed. See page B-5 for installation procedures and
B-6 for IR operation.
Infrared Remote Transmitter – This remote control transmits commands to the
Infrared Receiver described above.

Using System 8/10 PLUS as slave(s) to System 4
For large installations that require more inputs than one system switcher can
handle, multiple switchers can be looped together. Up to 17 switchers can be
looped together, providing a total of 154 inputs (using all System 10 PLUS
switchers). System 8/10 PLUS switchers can be looped together in different
combinations. Two connection schemes that are suitable for looping switchers
are called Daisy Chain and Star configurations.
When switchers are connected to work together, only one can communicate with
the projector and with the host system. This switcher is called the "Master". All
other switchers provide input to the Master, and they are called “Slaves”. Which
switcher operates as the Master is determined by two things:
1. How the cables are connected
2. How the Address switches are set
After a multiple switcher configuration is complete, the information must be
saved to the master switcher’s memory.
Saving Configurations to Memory
The System 8/10 PLUS has a memory to store the current connection scheme
(configuration). To save the configuration to memory, switch #4 of the Address
DIP switch, located on the rear panel of the Master Unit, must be set to the
Configuration (Down) position and the system operated for a minimum of 10
seconds. This provides sufficient time to save the configuration in the memory of
the Master Unit. After the configuration is saved, Address switch #4 is set to the
Normal (Up) position. The configuration sequence does not have to be repeated
until (or unless) the connection scheme is changed. This procedure will be
included as a step in the procedures that follow.
Master/Slave Configurations
The Star connection method (shown to the left) provides increased flexibility and
higher video performance than the Daisy Chain connection method. The
maximum number of inputs, however, is limited to 100 inputs when all switchers
are System 10 (1 master unit plus 10 slave units). If
using all System 8 switchers, the maximum number of
inputs is 64 (1 master unit and 8 slaves).
Inputs 1 - 10
Slaves #3 - 9
A simple example of the Daisy Chain method of
connection is shown to the right. It is the most
common looping method used for large analog RGB
switching systems. This method offers the largest
chaining configuration – 154 inputs when using all
System 10 switchers (1 master unit plus 16 slave
units). If using all System 8 switchers, the
maximum number of inputs is 120.

DIP Switch Types
Before going into the switch setups, let us first explain that there are different
types of DIP switches, some "slide" and some "rock". Your System 8/10 PLUS
could have either type DIP switch. Although they operate differently and are
labeled differently, they are simply on/off (open/closed) switches. Regardless of
the type of switch, we will show the positions as "up" or "down" and will use
arrows to show the switch position. The illustration to the left shows two types of
switches having the same configuration. Throughout this manual you may see
either type of switch, however, the switch positions will be the same.
Looping Two Switchers
A simple example of using multiple switchers is to use two System 8/10 PLUS
switchers. As explained on the previous page, the switcher feeding the projector
is the Master and the output of the Slave is one of the inputs to the Master.
1. See the figure below. Remove the power connections from both switchers and
decide which unit will be the Master Unit and which the Slave.
2. Disconnect all communications devices from the Master Unit.
_____ The only communications device that a Slave switcher can have connected is a
contact closure Manual Remote control (if required).
3. On the Master Unit, locate the DIP switches labeled "Address" in the lower right
corner of the rear panel. Set switches #3 and #5 up, and #1, #2 and #4 down.
(Switch #4 must be set to the "down" position until Step 9.)
4. On the Slave Unit, locate the Address DIP switches and set switches #1, 2, 3
and 4 up, and set switch #5 down for Slave Mode.
5. Connect the video output of the Slave Unit to
the last input of the Master Unit.
6. Connect an RJ11-to-RJ11 cable from the
"System Intercom Out" connector of the Master
to the "System Intercom In" connector of the
Slave.
Address

7. Connect the video outputs
from the Master Unit to the
video inputs of the
projector. (Go to Chapter 3
for the detailed projector
connections.)
8. To save the configuration
first turn the Slave On, and
then turn the Master On.
Wait at least 10 seconds
for the Master Unit to save
the configuration to
memory.

Daisy Chain Configuration
Daisy Chain Connection
Daisy Chain configuration refers to routing the output of the first slave (#0) into
the last input of the master switcher, and the output of the second slave (#1) into
the last input of slave #0... etc. All other inputs are used for various video
sources. The maximum number of inputs available in the daisy-chain
configuration is 154 when using all System 10 PLUS switchers (120 when using
all System 8 switchers). The Daisy Chain configuration is easy to configure, but
results in decreased system bandwidth due to the cascading signal path through
multiple switchers. As a further limitation of this connection scheme, it does not
allow the use of composite-to-RGB converters or scan doublers.
Looping Instructions
See illustration on the facing page as you do the following:
1. Remove power from all switchers and decide which will become the Master Unit
and which the Slave.
2. Disconnect all communications devices from the Master Unit.
_____ The Slave Units should never have any communications devices connected,
except a contact closure remote control (if required).
3. On the Master Unit, locate the DIP switches labeled “Address” in the lower right
corner of the rear panel. Set switches #3 and #5 up, and #1, #2 and #4 down.
(Switch #4 must be set to the “down” position until Step 9.)
4. On the first Slave Unit, locate the Address DIP switches and set switches #1, 2,
3 and 4 up (Slave # 0), and set switch #5 down, for Slave Mode.
5. Connect an RJ11 cable from the “System Intercom Out” connector of the Master
to the “System Intercom In” connector of Slave #0. If more slave units are being
connected, connect another RJ11 cable from Slave #0 “System Intercom Out” to
Slave #1 “System Intercom In”. Repeat this for each remaining slave unit in the
daisy chain.
Address
(#0)
6. Connect the video output of Slave #0 to the last input of the Master Unit.
Connect the output of Slave #1 to the last input of Slave #0. Repeat this for each
remaining slave unit in the daisy chain.
7. Connect any communication devices (e.g., projector control cable, remote
control, etc.) to the Master Unit.
8. Connect the video outputs from the Master Unit to the video inputs of the
projector. Refer to Chapter 3 for detailed procedures.
9. To save the configuration first turn the Slave On, and then turn the Master On.
Wait at least 10 seconds for the Master Unit to save the configuration to memory.
10. On the Master Unit, set Address switch #4 to the Normal, or “Up” position.
11. Make any necessary connections and put all switchers to normal operation.
_____ Video Loop Back (VLB) mode cannot be used when units are connected in this
configuration.

Star Configuration
Star Connection
In a Star configuration, the output of each slave supplies an input to the master
switcher. There is no slave #0 in a Star configuration. For example, slave #1 is
connected to input #1 of the master switcher; slave #2 is connected to master
input #2, etc. The output of the Master is connected to the projector or display
monitor. The maximum number of inputs available in a Star configuration is 100
when using all System 10 switchers (80 when using all System 8 switchers). The
Star connection scheme is somewhat more complicated to configure, but
provides maximum video bandwidth since the video signal is only routed through
two switchers. Another benefit of the Star configuration is the simple connection
of composite-to-RGB converters and scan doublers.
Looping Instructions
See illustration on the facing page as you do the following:
1. Remove power from all switchers and decide which will become the Master Unit
and which the Slave.
2. Disconnect all communications devices from the Master Unit.
_____ The Slave Unit should never have any communications devices connected,

The default protocol is 9600 baud, 8-bits, no parity and 1 stop bit. The baud rate
can be changed by setting an internal rotary switch.
_____ If the Host baud rate needs to be changed, go to B-3 and B-4.
Program Instructions
The System 8/10 PLUS openly recognizes any character that comes in on the
RS-232 port as a possible command. The characters shown in the Command/
Response table on page A-4 are the only valid commands that are recognized by
the System 8/10, any other character sent as a command will result in an error
response to the Host.
Simple Instruction Set
The Simple Instruction Set can be any ASCII character that is recognized by the
System 8/10 PLUS as a command. For this set, there are no codes required to
say that a command is coming or that a command has ended. Simple commands
could be from a terminal or any other controlling device. The System 8/10 PLUS
will execute the command and send a response back to the controlling device.
A simple command may be a single character typed on a keyboard and does not
require any special characters before or after (i.e. It is not necessary to press
“enter” from the keyboard.). However, some command characters may be
followed by a “delimiter” character which defines a specific request. The
System 8/10 PLUS looks at any character that comes in on the RS-232 port as a
possible command.
A-1
Extron • System 8/10 PLUS • User’s Manual
Terms
RS-232 Programming Guide
Related Terms
The following terms may be helpful in understanding information in the tables
and examples that follow.
Delimiter:
A delimiter character may specify audio and not video, the switcher and not the
projector, etc. For commands that have more than one character, the delimiter is
always the last character for that command string.
Carriage Return/Line Feed:
On most keyboards, pressing “enter” creates a carriage return (cr) and line feed
(lf). The screen cursor moves down one line and to the left margin. This is not
required for a command, but each response (as seen on a terminal display) will
be followed by a cr/lf (shown as ↵).
Discrete Command:
A “discrete” command can do only one thing. For example, if projector power is
already On, sending a “discrete power on” command does nothing.
Display, or Display Device:
“Display”, refers to the video output device (projector, monitor, etc.)
Host:
Any device capable of talking to the switcher through an RS-232 port.
Switcher:
“Switcher” refers to the System 8/10 PLUS or any slave inputs from other sources.
Terminal:
Any device that includes a keyboard and a display. This could be a “dumb”
terminal, a “smart” terminal, a PC operating in “terminal” mode, etc.
Toggle:
A “toggle” command can do either of two things. It changes the state of the
function, i.e. if the function was Off, the command turns it On; if the function was
On, the command turns it Off. A toggle command character may be upper or
lower case.
Zero:
In the examples that follow, the number zero is shown as Ø to distinguish it from
the letter “O”.
Selecting Inputs Using Delimiters
When selecting inputs to the projector and/or the System 8/10 PLUS, audio and
video can be switched together (follow) or separately (breakaway). An input is
selected by its decimal number followed by a delimiter character. The delimiter
ends the command and also determines which inputs are affected. The
delimiters are used as follows:
! - Audio and video (Aud/Vid) for the switcher (Sw) and video for the projector
(Dsp/Sw)
@ - Audio and video (Aud & Vid) for switcher only (Sw)
$ - Audio only (Aud) for the switcher (Sw)
& - Video only (Vid) for both projector and switcher (Dsp/Sw)
Examples:
5!
will select both audio and video from input channel #5.
132$ will select audio (only) from input channel #132. This is “breakaway”.
10&
will select video (only) from input channel #10. This is “breakaway”.

Command and Response
Command/Response Table
The Command/Response table lists commands, responses and data characters
recognized by the System 8/10 PLUS. The Command string (string = one or more
characters) in the left hand column of the table is defined in the right hand
column (both in Bold print). The Command string is shown as ASCII characters
and their hexadecimal (Hex) equivalent.
The Response string consists of one or more characters defining a function
followed by one or more characters defining the status of that function. A
carriage return followed by a line feed (↵ = CR/LF = ØDh ØAh) defines the end of
the Response string. Possible error responses, EØ1 - EØ4 and EØ6, are shown at
the bottom of the table.
In a basic configuration (no master/slave looping), the Channel Select command
selects one of eight or ten inputs. However, in a more complex looping
configuration, it is possible to have up to 154 inputs.

Manual Remote Control
Manual Remote Operation
The Manual Remote connector is a 25-pin D-Sub port used to remotely control
the System 8/10 PLUS switcher by dry contact closures to ground by using an
Extron hard-wired remote (optional KP-10) or another manufacturer's remote
control device. The connector also has a remote tally lamp capability to light
remote incandescent lamps or LEDs to indicate which input has been selected.
The following specifications are provided to allow the user to match other
devices to these specifications.
Connector Pin Assignments
Display Power. Pin 11 of the Manual Remote connector is used to switch
projector power. By making a dry momentary contact closure for one second
between pin 11 and ground (pin 25), the system switcher will command the
projector to turn ON. A subsequent one second contact closure will command
the projector to turn OFF.
Display Mute. Pin 24 of the Manual Remote connector is used to mute the
projector video. By making a dry contact closure between pin 24 and ground (pin
25), the system switcher will command the projector video image to mute (blank).
A subsequent momentary contact closure will restore the video image.
Input Channel Selection. Input channel selection is made by making a dry
contact closure between the desired input (pin 1 thru 10) and ground (pin 25).
Continuous dry contact closures can be made to select channels, but such
continuous connections made at the Manual Remote port override all other
means of input selection (i.e., takes precedence over front panel button
selections and RS-232 inputs from a host controller).
Tally Outputs
Remote Control
Connector Pin
Assignments:
Tally outputs (pins 14-23) offer means to poll a status from the System 8/10 to
determine which input is presently selected. The tally outputs also have the
ability to drive a remote front panel with lighted display. Tally outputs are
normally high (5 volts) and drop to a low (0 volts) when selected.

Infrared Remote Installation
Installing the Infrared Remote IC Chip
Before starting this procedure, verify that power has been removed from the
System 8/10 PLUS by removing the AC power cord.
_______ Use ESD protection by grounding yourself with an approved wrist strap. An
electrostatic discharge that is too small to be felt or seen is still capable of
destroying or causing intermittent damage to IC circuits.
1. Prepare the switcher by first following the procedure “Removing the System 8/10
PLUS Cover” on page B-3.
2. With the switcher placed on a clean workspace, the power removed and the
cover off, locate the vacant IC socket at U21 on the Main Controller Board. The
picture below shows the left side of the switcher with the cover removed.
3. Using ESD protection, remove
the IC chip from its packaging
and examine it to verify that all
pins (“legs”) are straight and in
perfect alignment.
4. Orient the chip with the socket,
with the notch to the front of
the switcher, as shown at U21
in the illustration.
5. Carefully align each pin on the
chip to its corresponding
female pin socket (see
illustration “e” on the left).
6. With even pressure, press the
chip into the socket (see illustration “f” on the left). If there is difficulty pressing it
into the socket, see if any pins ("legs") are bent. If so, carefully remove the chip,
straighten the leads and try again.
7. When the IC chip is installed, apply power to the System 8/10 PLUS by
connecting the AC power cord.
8. Follow the steps on the next page to check for correct operation of the Infrared
Remote system.
9. After checking the operation, replace the cover on the System 8/10 PLUS (page
B-3). The switcher is now ready for normal operation.
_____ The part number for this kit is 70-037-01.

Infrared Remote Operation
Reference
Infrared Remote Control Operation
_____ The IR-10 Remote control will also allow use of the Manual
Remote 25-pin D-Sub port, whereas the IR-30 Remote will
not.
Verify that batteries are installed in the IR-30 Remote
Transmitter. Note that the buttons on the IR remote are in two
groups.
• The four buttons across the top have the same names and
functions as the four colored buttons on the System 8/10
PLUS front panel.
• The second group includes numbered buttons, as well as
“Enter” and “Function” buttons. The numbered buttons
are used to enter values, such as channel numbers. The
“Enter” button is used to “send” the number to the
switcher. The “Function” button is reserved for future use.
SYSTEM REMOTE
______ Whenever the System 8/10 PLUS is receiving an IR signal
from the remote transmitter, the Main Power LED on the front
panel blinks. The LED on the Main Controller board, next to
the Infrared IC chip (U21), also blinks.
Check the IR-30 Remote operation as follows:
a. Point the transmitter (remote control) in the direction of the left front of the
System 8/10 PLUS and press each of the four top buttons, one at a time. For each
button pressed on the transmitter, the corresponding switch on the front panel
should light.
b. To select an input channel, press the button(s) for the channel number followed
by pressing
. For example, to select input #3, press 3,
. To select
input #10, press 1, 0,
.
_____ If the System 8/10 PLUS is looped, any available input channel is selected the
same way. For example, if a System 10 has another switcher as a Slave input,
selecting input channel #14 (1, 4,
) will cause the System 10 PLUS Master
to switch to the highest input (#10) and the Slave switcher will select its input #5.

4. Ease the chip out in steps (see illustrations “a” to “d” on the left) by pulling up
slightly on one end and then the other, as illustrated to the left. If you try to
remove it too quickly, you may damage the chip and/or the circuit board.
5. With the chip out of its socket, check the area for circuit board damage.
6. Examine the new software chip to be sure that all pins (“legs”) are straight and in
perfect alignment.
7. Orient the new chip to the socket with the notch to the right, as shown at U3 in
the illustration above.
8. Carefully align each pin on the chip to its corresponding female pin (see
illustrations “e” and “f” on the right).
9. Using even pressure, press the chip into the socket. If
there is difficulty pressing it into the socket, see if any pins
(“legs”) are bent. If so, carefully remove the chip (Step 4),
straighten the leads and try again (Step 7).
10. On the rear panel of the System 8/10 PLUS, locate the
Address Configuration DIP switches in the lower right
corner. Set DIP switch #4 to the down position (see illustration to the left). This
will reset the switcher.
11. When the software chip is installed, apply power to the System 8/10 PLUS by
connecting the AC power cord. After power is ON for at least 15 seconds, set
DIP switch #4 to the up position. The switcher has now been reset.

AC – Alternating Current –
Flow of electrons that changes direction alternately.
ADA – Analog Distribution Amplifier – A device that takes in one signal and distributes it
to several outputs without “tying” those outputs together (buffered).
Adapter – A linking device which allows two dissimilar devices to connect physically, and/or
communicate electronically.
AMPS – (Amperes) A unit of measurement for current.
Analog (Analogue) – A continuous action, or movement that takes time to change from one position to
another. Standard audio and video signals are analog. An analog signal has an
infinite number of levels between its highest and lowest value. (Not like digital,
where changes are by steps.)
ANSI – American National Standards Institute
ASCII – American Standard Code for Information Interchange. The standard code
consisting of 7-bit coded characters (8 bits including parity check), utilized to
exchange information between data processing systems, data communication
systems, and associated equipment. The ASCII set contains control characters
and graphic characters.
Aspect Ratio – The relationship of the horizontal dimension to the vertical dimension of a
rectangle. In viewing screens, standard TV is 4:3, or 1.33:1; HDTV is 16:9, or
1.78:1. Sometimes the “:1” is implicit, making TV = 1.33 and HDTV = 1.78.
Attenuation – The decrease in magnitude (of a signal).
Audio Follow – A term used when audio is tied to other signals, such as video, and they are
switched together. (The opposite of Breakaway)
Balanced Audio – A method that uses three conductors for one audio signal. They are plus (+),
minus (-) and ground. The ground conductor is strictly for shielding, and does not
carry any signal. Also called Differential Audio.
Bandwidth – A frequency range, or “band” of frequencies, within which a device operates. In
audio and video, it is the band of frequencies that can pass through a device
without significant loss or distortion. The higher the bandwidth, the sharper the
picture; low bandwidth can cause a “fuzzy” picture.
Black Level – More commonly referred to as “brightness”, the Black Level is the level of light
produced on a video screen.
Blanking – The turning off of the electron beam that scans the image onto the screen. When
the beam completes a scan line it must return (retrace) back to the left. During
this time, the beam must be turned off (horizontal blanking). Similarly, when the
last line has been scanned at the bottom of the screen, the beam must return to
the upper left. This requires vertical blanking.
Blooming – Most noticeable at the edges of images on a CRT, “blooming” is when the light
hitting the screen phosphors is so intense that it overdrives them. The edges of
an image seem to exceed its boundaries. Thin lines and sharp edges may look
thick and fuzzy. This may be caused by the brightness being set too high, or by a
high voltage problem.
BNC – It is a cylindrical Bayonet Connector which operates with a twist-locking motion.
Two curved grooves in the collar of the male connector are aligned with two
projections on the outside of the female collar. This allows the connector to be
locked in place without the need of tools.
Breakaway – The ability to separate audio and video signals for the purpose of switching them
independently. For example: an audio and video signal from the same source
may be “broken away” and switched to different destinations. This is the opposite
of the term “audio follow”.

Brightness – Usually refers to the amount, or intensity of video light produced on a screen.
Sometimes called “black level”.
Buffer – Generally referred to as a unity gain amplifier used to isolate the signal source
from the load. This is for both digital and analog signals.
C– In S-Video, “C” is an abbreviation for Chrominance, or the color information. (“Y”
is for Luminance, or the brightness.)
Cable Equalization – The method of altering the frequency response of a video amplifier to
compensate for high frequency losses in cables that it feeds. (See Peaking.)
Capacitance – The storing of an electrical charge. At high frequencies, capacitance that exists
in cables also represents a form of impedance.
Chroma – The characteristics of color information, independent of luminance intensity. Hue
and saturation are qualities of chroma. Black, gray, and white objects do not
have chroma characteristics.
Chrominance Signal – Part of a television signal containing the color information. Abbreviated by “C”.
Coaxial Cable – A two-conductor wire in which one conductor completely wraps the other with the
two separated by insulation. Constant impedance transmission cable.
Color – An Extron adjustment that is used to control color intensity.
Component Video – Our color television system starts with three channels of information; Red,
Green, & Blue (RGB). In the process of translating these channels to a single
composite video signal they are often first converted to Y, R-Y, and B-Y. Both 3channel systems, RGB and Y, R -Y, B -Y are component video signals. They are
the components that eventually make up the composite video signal. Much
higher program production quality is possible if the elements are assembled in
the component domain.
Composite Sync – A signal combining horizontal and vertical sync pulses, and equalizing pulses,
with no picture information. Sometimes called ”C”, “S” (as in RGBS) or “HV”.
Composite Video – An all-in-one video signal comprised of the luminance (black and white),
chrominance (color), blanking pulses, sync pulses and color burst.
Contrast – The range of light and dark values in a picture, or the ratio between the
maximum and the minimum brightness values. Low contrast is shown mainly as
shades of gray, while high contrast is shown as blacks and whites with very little
gray. It is also a TV monitor adjustment which increases or decreases the level
of contrast of a displayed picture. Also called “white level”.
Crosstalk – Interference, usually from an adjacent channel, which adds an undesirable signal
to the desired signal.
Crosstalk Isolation – Attenuation of an undesired signal introduced by crosstalk.
CRT (Cathode Ray Tube) – A vacuum tube that produces light on a screen when energized by the electron
beam from inside the tube. A CRT has a heater element, cathode, and grids in
the neck of the tube, making up the “gun”. An electron beam is produced by the
gun and is accelerated toward the screen surface of the tube. The screen’s
inside surface is coated with phosphors that light up when hit by the electron
beam. The CRT is more commonly known as the picture tube. Some color CRTs
have three guns – for red, green and blue colors.
DAT (Digital Audio Tape) – A method developed by Sony and Hewlett-Packard for recording large amounts
of information in digital form on a small cassette tape. It uses a rotating helical
read/write head, similar to the technique used on a VCR.
dB (Decibel) – The standard unit used to express gain or loss of power. It indicates the
logarithmic ratio of output power divided by input power. A power loss of 3 dB is
an attenuation of half of the original value. The term “3dB down” is used to
describe the “half power point”.

as another device, a video screen, image or hard copy.
PAL ( Phase Alternate Line) – The phase of the color carrier is alternated from line to line. It takes four full
pictures for the color to horizontal phase relationship to return to the reference
point. This alternation helps cancel out phase errors, the reason the hue control
is not needed on PAL TV sets. PAL, in its many forms is used extensively in
Western Europe.
Peak-to-Peak – (abbreviated p-p) The amplitude (voltage, for example) difference between the
most positive and the most negative excursions (peaks) of a signal.
