Model 8/10 PLUS Introduction and Specifications
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, S-Video, Composite
Video, and Audio.
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.
Triple Action SwitchingTM (RGB Delay) – Triple Action
SwitchingTM is a technique in which the RGB video is blanked
for a brief period when a new input is selected. This prevents
a distorted image from being displayed during the time the
display device sync circuitry is locking onto the new sync
input. When an input is selected, Triple-Action Switching®
does this:
1. Drop the RGB video signals leaving sync connected.
2. Wait for 20 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.)
Switcher Control – Each channel of the switcher can be
controlled in any one of the following ways:
1. Front Panel Buttons.
2. Manual Remote Control Connector – KP-10 Wired
Remote Control, IR-10 Infrared Remote Control or third
party remote control.
3. RS-232 Control Connector – Provides for computer/serial
control of the switcher.
Internal Power Supply – The Model 8/10 PLUS switchers have
an internal, auto-switching (100 - 240 VAC, 50/60 Hz) power
supply. The Model 8/10 PLUS switchers are UL, CE and CSA
approved.
Rear Panel LED Indicators – Rear panel LEDs indicate which
input is selected and which outputs are active.

Model 8/10 Switcher Operation
The Model 8/10 PLUS switchers enable the output to be
switched from anyone of 8 or 10 inputs (A)* and the following
formats are supported:
• RGBS – RGB with separate composite sync
• RGsB – RGB with sync on green
• Monochrome Composite Video
• NTSC/PAL (Composite) Video w/Stereo Audio follow
• S-Video (SVHS) w/Stereo Audio follow
When an input is selected, an LED will illuminate green next
to the selected BNC input connectors on the rear panel (H)*.
Three sets of output connectors are used for the four different
video format outputs. They are:
• RGB (RGBS or RGsB) – 4 BNC connectors (B)*
• VIDEO (NTSC/PAL) – 1 BNC connector (C)*
• S-Video (SVHS) – 1 S-Video DIN connector (D)*
Audio, if used, is available on the two output BNC connectors
labeled AUDIO (L and R) (E)*.
Only one set of output connectors is active at a time. The
current active set is identified by an illuminated LED next to
the active output connector(s) (F)*.
The Output Select DIP Switch (G)* settings will determine
which of the three output connectors that the selected input
will be directed to. These switches must be set for each input
to match the incoming format. There are two switch modules,
the left switch module is for RGBS/S-Video selection and the
right switch module is for RGBS/NTSC-PAL selection. The
switch modules are numbered from top to bottom to match the
input number.
Front Panel
The POWER LED (see front panel drawing below), when
illuminated, indicates that the switcher power is on. If AC
voltage is available to the switcher, it is powered on.
Front Panel switches 1 – 10 (Model 8 = 1 – 8) shown in the
drawing below may be used to select the input. The LED in
the front panel switch for the selected input will be illuminated.

Output Select DIP Switch Setting
As mentioned earlier, the Output Select DIP switches must be
set to define the video format of each input. The DIP Switch
modules, labeled S-VIDEO/SVHS and NTSC/PAL are shown
in the drawing at the bottom of this page. Each module has 10
(8 if Model 8 PLUS) switches which are numbered to match
the input numbers. RGBS and VIDEO labels under the switch
modules identify the left and right switch positions. When
setting the Output Select Switch Module switches, use the
following rules as a guide:
• All RGB inputs must have the corresponding switch positions
on both switch modules set to RGBS. If all switcher inputs are
RGB format, all of the Output Select DIP switches must be set
to the RGBS position.
• All S-Video inputs must have the corresponding switch
positions on the S-VIDEO/SVHS module set to VIDEO. The
corresponding NTSC/PAL switches must be in the RGBS
position.
• All NTSC/PAL inputs must have the corresponding switch
positions on the NTSC/PAL switch module set to VIDEO. The
corresponding S-Video switches must be in the RGBS position.
The DIP switch modules used in the Model 8/10
PLUS switchers are the "rocker" type (see end
view drawing to the left). The major difference
between the rocker type and the "slide" type
(which could also be used) is the action
required to change the position of the switch.
To change the position of the rocker
type switch, press down on the
desired end (RGBS or VIDEO) with
a pointed object. To change the
position of the slide switch, a small
screwdriver is used to push (slide)
the switch to the desired position
(RGBS or VIDEO).
See examples on facing page.

Changing the Baud Rate
The RS-232 protocol factory setting is 9600 baud, 8-bits, no
parity, 1 start bit and 1 stop bit. The position of internal rotary
switch SW3 on the main controller board controls the baud
rate and parity. To change the switch setting, remove the four
screws from the top of the case and lift the cover straight up.
Locate SW3 (see drawing below) and use a small, flat blade
screwdriver to rotate the switch to the desired position. SW3
switch positions are defined in the table below.
8-bit, no parity, 1 stop bit 8-bit, odd parity, 1 stop bit
0 = 300 baud 8 = 300 baud
1 = 600 baud 9 = 600 baud
2 = 1200 baud A = 1200 baud
3 = 2400 baud B = 2400 baud
4 = 4800 baud C = 4800 baud
5 = 9600 baud D = 9600 baud
6 = 19200 baud E = 19200 baud
7 = 38400 baud F = 38400 baud
_ Adjust SW3 to set the RS-232 Baud Rate and Protocol.

computer (PC) serial port to the Model 8/10 PLUS Switcher
connector labeled RS-232.
Model 8/10 PLUS Operation and Configuration
Triple Action Switching
TM
(RGB Delay)
This prevents image scrambling during switching time. When
an input is selected, Triple Action Switching®does this:
1. Drop the RGB signals.
2. Wait 20 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.)
SW9 is used to set the 0.0 - 7.5 second delay (See drawing
on facing page). Each position of the switch changes the
delay by 0.5 seconds and the adjustment range is 0.0 (Switch
position 0) to 7.5 seconds (Switch position F). The switcher
ships with SW9 set to the 0 position (0.0 seconds).
To change the SW9 switch position, remove the four screws
from the top of the case and lift the cover straight up. Use a
small, flat blade screwdriver to rotate the switch to the desired
switch position. The switch position can be calculated by
measuring (estimating) the period of time that the video
appears out of sync after switching to a new input, then
multiply the time period by 2 to determine the switch position.
Example:
Measured out of sync period = 4 seconds
4 x 2 = 8 (The required switch position for 4 seconds is #8.)
The switch positions above 9 are labeled in hexadecimal, i.e.
switch position 10 is labeled A on the switch. (10Dec = AHex,
11 = B, 12 = C, 13 = D, 14 = E and 15 = F)

Model 8/10 PLUS RS-232 Control
The Model 8/10 PLUS switchers can be controlled through the
RS-232 port by a Host device/system. The RS-232 connector
location and pin assignments are shown in the drawing below.
Software
Each Model 8/10 PLUS switcher ships with a 3.5" diskette
containing Extron's Windows® compatible UNIVSW Control
Software which enables the user to select the input and check
switcher status in a Windows “point and click” environment.
This software will be covered later in this chapter.
Host/Switcher Communications
The Model 8/10 PLUS Switchers treat any character that
comes in on the RS-232 port as a possible command but
accepts only a limited number as legal commands. There are
no codes required to say that a command is coming, or that a
command has ended. 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.) Simple commands could be
from a terminal, or any other controlling device.
When the Model 8/10 PLUS switcher receives a command
and determines that it is valid, it will execute the command
and send a response back to the controlling (Host) device. If
the command is determined by the Model 8/10 PLUS switcher
to be invalid, an error response will be returned to the Host.
All responses from the switcher to the Host begin and end
with a carriage return and a line feed (CR/LF) signaling the
end of the Response character string (string = one or more
characters).
Using the Command/Response Table
The table on the following page lists those commands which
the Model 8/10 PLUS switchers recognize as valid and the
responses that will be returned to the Host. The Description
column defines the Command, the results of executing the
Command, or a definition of the response.
The Command string in the left hand column of the table is
defined in the right hand column. The Command string is
shown as ASCII characters, an ASCII to HEX conversion
table is provided.
