MT105-108
Re-configurable VGA-QXGA Video
Matrix Switcher Cards
The MT105-108 is a re-configurable VGA-QXGA
Video Matrix Switcher Card designed to route both
broadcast and computer video to audio/visual
presentation systems.
This card may be configured to provide different
matrix sizes. There are two fixed inputs and two
fixed outputs. Additionally, there are four
re-configurable Input/Output ports. These four
ports are configured with jumpers to be either input
or output ports. For example, the card can be
configured as a 2-In/6-Out matrix or a 6-In/2-Out
matrix just by changing jumper positions.
Size Fixed
Input I/O set to IN Fixed Output I/O set to OUT
2x6 2024
3x5 2123
4x4 2222
5x3 2321
6x2 2420
The MT105-108 provides an economical
application for VGA-QXGA type video signals. This
card is designed for 150 MHz bandwidth
performance.
Inputs are selected through easy-to-use ASCII
commands from a control system or computer
connected to the RS-232 port of the Multi-Tasker
Enclosure.
A special feature of the MT105-108 is Sync Delay
to eliminate the appearance of video signals
before the display device is able to process the
sync signals and properly format the video image.
The Sync Delay is the amount of time to wait after
switching the Horizontal and Vertical Sync signals
and before switching the RGB signals. Each output
may be programmed with a delay ranging from
zero to 24.75 seconds, in increments of 250mS.

INSTALLING YOUR MULTI-TASKER™ 6
Step 1. Determine the desired configuration for
the MT105-108 and set the jumpers
appropriately. The MT105-108 can be set
as follows:
2 Inputs - 6 Outputs
3 Inputs - 5 Outputs
4 Inputs - 4 Outputs
5 Inputs - 3 Outputs
6 Inputs - 2 Outputs
Step 2. Set the jumpers as described in the
Jumpers Settings diagram. Each jumper
is a 10-pin ribbon cable assembly.
Step 3. Slide the MT105-108 into an available
slot in the Multi-Tasker™ Enclosure in
order to connect to the bus. Make sure
that the MT105-108 card fits into place.
Secure the card to the Multi-Tasker™ by
tightening the retainer screws located on
the top and bottom of the MT105-108.
Step 4. Connect a VGA cable from one or more
video sources to the input connectors of
the MT105-108.
Step 5. Connect one or more of the output
connectors of the MT105-108 to display
devices through VGA cables.
Step 6. Starting from the left, identify the slot
number where the MT105-108 card is
plugged into the Enclosure and note that
it is for RS-232 control.
OPERATION 7
7.1 RS-232 CONTROL
When used in the Multi-Tasker™ Enclosure, the
MT105-108 has many advanced remote control
capabilities, which are accessible through standard
RS-232 communication. The actual controlling can
be accomplished through a computer control
system or any other device capable of sending
RS-232 commands.
7.1.1 RS-232 INTERFACE
The RS-232 commands, for the MT105-108,
are in a simple ASCII character format.
1. Square brackets “[ ]” are part of the
command.
2. Use uppercase letters for all commands.
After processing a command, an OK or ER will
be returned as feedback if "F" is included at the
end of a command string.
Commands ending in "S" will be saved into
memory. Commands not ending in "S" will still
be executed but will not be restored when the
system is reset or powered OFF then ON.
7.2 DESCRIPTION OF COMMANDS
Each command consists of three parts:
Function, Card ID, and Unit ID.
[Function , Card ID , Unit ID ]
Example: [VERC3U2]
VER = Function
C3 = Card ID or Group ID
U2 = Unit ID
For Function, see a detailed explanation under
each command description.
The Card ID is an assigned value. It is equal to
the enclosure slot number in which the card is
installed. The value can range from 1 to 4 up to
1 to 20 depending on the enclosure.
Card ID 0 (C0) is used for the controller. See
the MT100-100 User’s Guide for details.

MULTI-TASKER™
400-0218-003 8
The Group ID is a number representing a group
of cards defined with the [WR] command.
When using the Group ID, all cards in the group
will perform the given instruction.
Changing the position of a card will significantly
affect the commands recorded on software
definitions or third party control systems.
The Unit ID has a value from 0 to 9. Unit ID 0
should be used for single unit operation. If the
Unit ID is set to zero, each command may be
used without Ui. Use the command [SETU0],
as explained in the MT100-100 User’s Guide.
Example:
[VERC3]: For Unit ID Zero
[VERC3Ui]: For Unit ID other than Zero
[VERC3]: Equivalent to [VERC3U0]
1. [VER]
This command displays the software version
and card type for the MT105-108 card.
Command Format: [VERCnUi]
Cn = Card ID (n = slot # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)
Example:
An MT105-108 card is in slot #4. Send the
command [VERC4], and the Multi-Tasker™
Enclosure will return the following feedback:
MT105-108 690-0170-003
MT105-108 = the card model
690-0170-003= the software version
2. [C]
This command displays the status of the card
and connections of the Matrix Switcher.
Command Format: [CnUi]
Cn = Card ID (n = slot # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)
Example:
An MT105-108 card is in slot #2. Outputs
1, 2 and 3 are ON. Input 1 is connected to
Output 1 and Input 2 is connected to all the
remaining outputs.
Sending the command [C2] will yield the
following feedback:
In1-Out1 ON
In2-Out2 ON
In2-Out3 ON
In2-Out4 OFF
In2-Out5 OFF
In2-Out6 OFF
In2-Out7 OFF
If there is no card in slot #2, sending the [C2]
command will not return any feedback.
NOTE: The feedback will always show seven
outputs regardless of the matrix
configuration set by the physical
jumpers.
3. [CnS]
This command saves the input to output
settings, as well as, the ON/OFF status of each
output. This configuration will be restored after
the system is reset or powered off then on.
Cn = Card ID (n = slot # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)
Example:
There is an MT105-108 in slot #4. Input 1 is
connected to all outputs, but only outputs 1
through 3 are ON. The feedback after sending
the command [C4S] would be:
In1-Out1 ON
In1-Out2 ON
In1-Out3 ON
In1-Out4 OFF
In1-Out5 OFF
In1-Out6 OFF
In1-Out7 OFF
Saved

MULTI-TASKER™
400-0218-003 9
4. [?CnUi]
This command will return general information
about the card and its status. It is a function of
both the card and the front panel and is only
available with Multi-Tasker™ Front Panel
systems that have the following firmware:
690-0122-015 = Version 015 or later.
690-0123-004 = Version 004 or later.
690-0124-018 = Version 018 or later.
NOTE: In MTSetup™, send the command
[VER] from the Terminal Window. The system
will respond with feedback similar to the
following:
[690-0122-015 690-0123-004 690-0124-018]
Check the last three digits against the numbers
above to determine if the MENU MODE option
is available.

Example:
The MT105-108 in slot #4 has Input 1
connected to all outputs and all outputs turned
ON. Send the command [?C4] to receive the
feedback status.
Each status field begins with a '+' and ends with
the card slot number (ex: C04). The feedback
will be similar to the following:
[+MT105-108C04+VR690-0170-003C04
+ON1111111C04+MA01010101010101C04]
MT105-108 = Card Type
VR690-0170-003 = Firmware version
ON1111111 = Output ON/OFF status
MA01010101010101 = Matrix I/O connections
The ON/OFF status line is read from left to right
as outputs one through seven. A "1" indicates
the output is ON and a "0" indicates the output
is OFF.
The I/O connections are also read left to right
representing outputs one through seven and
the input to which each it is connected. The first
two digits show the input number to which
Output 1 is connected.
5. [SDL]
This command displays the Sync Delay
programmed for each output.
Command Format: [SDLCnUi]
Cn = Card ID (n = # from 1 to max slots)
Ui = Unit ID (i = from 0 to 9)
Example:
There is an MT105-108 in slot #4. Send the
command [SDLC4] and feedback similar to the
following:
SYNC DELAY FOR OUTPUT 1 THROUGH 8
(SDL1 to SDL8):
SDL1=01 (00.25 Sec)
SDL2=03 (00.75 Sec)
SDL3=04 (01.00 Sec)
SDL4=10 (02.50 Sec)
SDL5=20 (05.00 Sec)
SDL6=00 (00.00 Sec)
SDL7=00 (00.00 Sec)
SDL8=00 (00.00 Sec)
6. [SDLm=s]
This command sets the Sync Delay for each
output. The Sync Delay is the amount of time to
wait after switching the Horizontal and Vertical
Sync signals to the new output. When switching
input to output connections, the RGB signals
are disabled first. Then, the RGBHV signals are
switched to the new output with the H and V
signals enabled. After the delay, the RGB
signals are enabled on the new output. Each
individual output may be programmed with a
Sync Delay ranging from zero seconds to 24.75
seconds in increments of 250mS.

MULTI-TASKER™
400-0218-003 10
Command Format: [SDLm=sCnUi]
m = Output (m = # 1 to 7)
s = Sync Multiplier (s = # from 0 to 99)
Delay = Multiplier X 250mS.
Cn =Card ID (n = # from 1 to max slots)
Ui =Unit ID (i = from 0 to 9)
Example:
There is an MT105-108 in slot #4. Send the
command [SDL1=4C4] to set the Sync Delay
for Output 1 to one second.
7. [STA]
This command enables and disables automatic

but it is not active until the switch command,
[SW], is executed. Commands ending in "P" are
not executed immediately. The path for outputs
on multiple cards or the same card may be
preloaded.
m= Output (m = # from 1 to 7)
Cn = Card ID (n = # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)
P= Path
Example:
There are two MT105-108 cards in slots 6 and
7. Disable Output 1 of card 6 and Output 3 of
card 7 simultaneously using the following
commands:
[OFF1C6P]
[OFF3C7P]
[SW]
If "F" is included, use the [OFFmCnPF]
command or the [OFFmCnFP] command.

FEEDBACK OPERATION
Command Format: [OFF…..F]
After processing a command, an OK or ER will
be returned as feedback if "F" is included at the
end of a command string.
Example:
[OFF1C2F]: if path is not set
[OFF1C2PF]: if path is set
10. […S] – SAVE
This command will save the configuration
command being sent in memory. When
sending the command [I1O1C4S], after reset or
power up, Input 1 will be connected to Output 1
on C4. This command only saves the Input 1 to
Output 1 connection above. In order to save all
the current settings, use the [CnS] command.
11. […F] – FEEDBACK
After processing a command, an OK or ER will
be returned as feedback if "F" is included at the
end of a command string.
12. […P] – PATH
This command will set the path for the output,
but it is not active until the switch command,
[SW], is executed. Commands ending in "P" are
not executed immediately. The path for outputs
on multiple cards or the same card can be
preloaded. See the examples in the ON and
OFF command descriptions.
Example:
There is an MT105-108 in slot #4. Currently,
Input 1 is connected to all outputs and all
outputs are ON. The PATH command has been
used to set Input 2 to Output 1 and turn OFF
Outputs 2 and 3 at the same time. If checking
the status prior to sending the [SW] command,
the feedback will appear as follows for the
above connection settings:
In1-Out1 ON P=2
In1-Out2 ON P=OFF
In1-Out3 ON P=OFF
In1-Out4 ON
In1-Out5 ON
In1-Out6 ON
In1-Out7 ON
The notation "P=" at the end of the line
indicates the path condition is active. "P=2" on
the Output 1 line indicates that after the [SW]
command, Input 2 will be connected to Output
1.
The notation "P=OFF" on lines 2 and 3
indicates that Outputs 2 and 3 will be turned
OFF after the [SW] command is executed.
13. [SW] – SWITCH
This command immediately connects inputs
and outputs previously set with the PATH
command. The command switches all paths
set on this card and all other cards in the
enclosure.
Example:
The following commands set the path for
turning ON Output 1 of the card in slot #6 and
turning OFF Output 3 of the card in slot #7.
Nothing happens until the [SW] command is
sent. At that time, Output 1 will be enabled and
Output 3 will be disabled.
[ON1C6P]
[OFF3C7P]
[SW]
14. [IO]
This command will connect a single input with
one or all outputs. It will not effect the ON/OFF
status of the output.
Command Format: [IxOyCnUi]
x = Input (x = # from 1 to 6)
y = Output (y = # from 1 to 7, or [for all)
Cn = Card ID (n = # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)

MULTI-TASKER™
400-0218-003 13
Example:
An MT105-108 is in slot #4 Connect Input 1 to
all outputs by sending the command [I1O[C4].
After the command is sent, Input 1 will be
connected to all outputs. In order to turn ON all
the outputs, send the command [ONC4].
15. [CLR]
This command resets the card configuration to
the factory defaults. After the [CLR] command,
Input 1 will be connected to all outputs and all
outputs will be ON.
Command Format: [CLRCnUi]
Cn = Card ID (n = # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)
Example:
Send the command [CLRC4] to reset the card
in slot #4 to its factory defaults.
16. [TEST]
This command performs a test on the internal
memory. Upon completion, the system will
display the results. If there are no problems, the
system will display the following:
MEMORY IS GOOD
Otherwise, failures will be indicated.
Command Format: [TESTCnUi]
Cn = Card ID (n = slot # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)
Example:
There is an MT105-108 in slot #4. Send the
command [TESTC4] to test the internal
memory.
17. [HELP]
This command displays information available
for the Multi-Tasker interface commands.
NOTE: There is no signal detect capability on
the MT105-108. The [SIGI] and [SIGO]
commands in the HELP file don't apply.
Command Format: [HELPCnUi]
Cn = Card ID (n = # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)
Example:
In order to display the RS-232 commands
available for the MT105-108 card in slot #2,
send the command [HELPC2]. The commands
along with a brief description will be displayed
in the Terminal Window.
18. [WR]
This command groups multiple cards in the
enclosure allowing all the group members to be
controlled simultaneously with the same
command. Each unit may define a maximum of
eight groups.
In Multi-Tasker™ systems with audio and video
cards, boards are typically grouped as follows:
Group 1 = Video Cards
Group 2 = Audio Cards
Group 3 = Video and Audio Cards
If assigning group commands to button
functions, it is best to use the "Press and Hold
on Power Up" to make group settings.
Command Format: [WRCn1Cn2…GkUi]
Cn = Card ID (n = slot # from 1 to max slots)
Gk = Group number (k = # from 1-8)
Ui = Unit ID (i = # from 0-9)
Example:
To group cards 1, 2, and 3 as group 5 of
Unit ID 1, send the command
[WRC1C2C3G5U1]. After executing this
command, cards 1, 2 and 3 will be grouped
together as group 5 of Unit ID 1. The system
will return the following feedback:
G1=C1C2C3
Now, when a command is sent to G1, each
board in G1 will execute the same command.

MULTI-TASKER™
400-0218-003 14
19. [RMC]
This command may be used to remove one or
more group members from a group.
Command Format: [RMCn1Cn2…GkUi]
Cn = Card ID (n= # from 1 to max slots)
Gk = Group number (k = # from 1-8)
Ui = Unit ID (i = # from 0-9)
Example:
Group 1 consists of the cards located in slots
numbered 1, 2, 3, 4 and 5. Remove just cards
#4 and #5 from the group by sending the
command [RMC4C5G1]. The system will return
the following feedback:
G1=C1C2C3
20. [RMG]
This command may be used to delete an entire
group, or all groups.
REMOVE ONE GROUP MEMBERS
Remove all the members from the group,
effectively deleting the group.
Command Format: [RMGkUi]
Gk = Group number (k = # from 1-8)
Ui = Unit ID (i = # from 0-9)
Example:
Group 1 consists of the cards located in slots
number 1, 2 and 3. Remove all cards from the
group by sending the command [RMG1]. The
system will return the following feedback:
G1=EMPTY
REMOVE ALL GROUPS
Remove all the members from every group,
effectively deleting all groups.
Command Format: [RMG[Ui]
Ui = Unit ID (i = # from 0-9)
Example:
Group 1 consists of cards 1 and 2. Group 2
consists of cards 1, 2, 3, 4 and 5. Delete all the
groups by sending the command [RMG[]. The
system will return the following feedback:
G1-G8:EMPTY
21. [RD]
This command reads and then displays the
members in each group.
Command Format: [RDGkUi]
Gk = Group number (k = # from 1-8)
Ui = Unit ID (i = # from 0-9)
Example:
The cards in slots 1, 2 and 19 are part of
group 5. Read the member data for group 5, by
sending the command [RDG5]. The system will
return feedback as follows:
G1=C1C2C19
The feedback shows G1 (Group 1) and then the
cards that make up Group 1. In this case,
Group 1 includes C1, C2 and C19.
22. [CLRG]
This command clears the members for a single
group or for all groups. The clear command
restores the cards to default settings and is the
equivalent to sending the [CLR] command to
each individual card.
NOTE: Since this command is sending the
[CLR] command to its group members,
each card will display its own reset
message, if any.
Command Format: [CLRGkUi]
Gk = Group ID (k = # from 1-8, or [for all)
Ui = Unit ID (i = # from 0-9)

MULTI-TASKER™
400-0218-003 15
Example:
1) To clear group 1 of Unit ID 0, send the
[CLRG1] command. This command clears
the members for the specified group only.
2) To clear all groups of Unit ID 1, send the
[CLRG[U1] command.
23. [CLM]
This command removes the members in a
group and leaves the group empty. It is
equivalent to sending the [RMGkUi] command
without card references.
Command Format: [CLMGkUi]
Gk = Group number (k = # from 1-8)
Ui = Unit ID (i = # from 0-9)
Example:
Group 5 of Unit ID 1 contains the cards in slots
1, 2 and 19. Read the member data for group 5
of Unit ID 1. Send the command [RDG5U1]
and receive the following feedback:
G1=C1C2C19
Now, clear group 5 by sending the command
[CLMG5U1]. Reread the member data as above
and note the following feedback:
G1=EMPTY

7.4 MENU MODE
MENU MODE commands are RS-232 commands
that allow virtually the same functionality as
programming commands. Unlike the programming
commands in the previous sections, 7.2 and 7.3,
MENU commands prompt the user to select from a
list of available options. The system then responds
based upon selections made by the user.
MENU commands may be issued in response to
prompts from within MTSetup™ or other RS-232
communication software.
The MENU driven commands are only available
with Multi-Tasker™ Front Panel systems that have
the following firmware:
690-0122-015 = Version 015 or later.
690-0123-004 = Version 004 or later.
690-0124-018 = Version 018 or later.
NOTE: In MTSetup™, send the command [VER]
from the Terminal Window. The system will
respond with feedback similar to the following:
[690-0122-015 690-0123-004 690-0124-018]
Check the last three digits against the numbers
above to determine if MENU MODE is available.

7.4.2 USING MENU MODE
SUGGESTION: Before using the menu mode, it
is best to disable the automatic feedback
feature. The values and current settings will be
displayed in the menu mode, but the automatic
feature will display after each setting change
making the menus difficult to read.
1. In order to run MENU mode, the system
must be connected to a computer running
MTSetup™ or other RS-232 control
software.
2. Insert the card into an empty slot and push
in all the way for a secure fit.
3. Reset the system or power the system OFF
and then ON.
4. In MTSetup™, click in the Terminal Window
then press the ENTER key.
5. The system interrogates the enclosure and
returns a list of cards installed and their slot
locations.
Example: 4 (Slot 4): MT105-108
NOTE: Only cards supporting the MENU
feature will be displayed.
5. Find the alphanumeric character
representing the card whose setup requires
changing. It's the first character in the line.
6. Press the number or letter associated with
the card, and a menu with options available
for that card will appear on the screen. In
the example above, press "4".
WARNING: Do NOT enter any characters
except the one relating to the desired
menu. Pressing ENTER or RETURN after
"4" will force the system back to the original
prompt.
7. After selecting the MT105-108 as described
above, the system will prompt for selections
specific to that card.
8. Read each menu carefully, and continue
selecting keys as prompted for further
functions. (Example prompt: "Key= ")

7.4.3 MENU TYPES
1. MAIN MENU
The first menu displayed after selecting the
card is the Main Menu. This menu provides
access to the main functions related to the
card. Press the key representing the menu
item for access. A sub menu will appear
next.
2. SUB MENUS
Each sub menu will display either another
menu (sub menu) or a list of available
options or settings. Press the key
corresponding to the menu choice to
change a setting or select the next menu.
NOTE: Pressing the ESCAPE (ESC) key in
most menus will take you up to the
previous menu without making changes in
the current menu. In the some menus, the
ESC key is used to confirm the card/group
selection or new settings.
7.4.4 MT105-108 MENUS
Following are the menus available to the
MT105-108. The first menu is the Main Menu
only. The second listing is an expansion of all
the menu items.
The expanded menu contains values in
parentheses that indicate the current setting or
value of that parameter. In some areas,
additional comments are provided for
clarification.
Some menu settings act as toggle features. For
example, the ON/OFF command for each
output as only one option. If Output 1 is ON,
pressing 1 in the ON/OFF menu will turn Output
1 OFF. Pressing it again will turn Output 1 ON
again. In short, pressing 1 repeatedly will toggle
Output 1 ON and OFF.
System prompts requiring specific values for
input numbers or output numbers, card number
etc… are not shown. See the examples
following the menus for details.
The IN-OUT menu requires the user to input the
numeric value of the input to switch, then it will
prompt for the output to which the input will be
switched. After each change, the system will
respond with "ok". Entering "S" will redisplay the
connection settings.
The Sync Delay menu will prompt the user to
select the output number for delay. After that,
the system will display a one line prompt so the
user can enter the Sync Delay value.
CAUTION: Pay special attention to the top of
the CONTROL menu. After selecting the
CONTROL menu, THIS CARD or a group
number will be identified at the top of the sub
menu. Since group functions may be modified
from this menu, make sure the desired card or
group is selected.
