5. About Your MT105-120/121
The MT105-120/121 are VGA-UXGA Video Matrix Switcher Cards designed to switch high bandwidth RGBHV video signals. The MT105-120 card has eight
inputs and eight outputs with 15 pin HD connectors. The MT105-121 has eight inputs and four outputs, also with 15-pin HD connectors.
Both cards provide signal detection on input and output through horizontal s nc. This feature allows for eas remote diagnostics throughout RS-232 commands,
from the source all the wa to the output connectors.
The MT105-120/121 provide an economical application due to the space saving design using D-connectors instead of BNC connectors.
Inputs are switched to outputs through eas -to-use ASCII commands from a control s stem or computer connected to the RS-232 port of the MultiTasker
enclosure. Both cards allow disabling of video outputs through RS-232 commands. Inputs and outputs ma be programmed in batches and switched all at the
same time with a single command.
Used in conjunction with the MT110-100 and MT110-101 Audio Matrix Switcher cards, it is possible to group audio and video inputs and outputs together. Once
grouped, the cards ma be switched as audio and video or independentl .
A special feature of the MT105-120/121 is S nc Dela which eliminates the appearance of video signals before the displa device is able to process the s nc
signals and properl format the video image. The S nc Dela is the amount of time to wait after switching the Horizontal and Vertical S nc signals and before
switching the RGB signals. Each output ma be programmed with a dela ranging from zero to 24.75 seconds, in increments of 250mS.

7. Operation
7.1 RS-232 Control
The MT105-120/121 has man advanced remote-control capabilities
accessible through standard RS-232 communication using a computer,
control s stem, or an device capable of RS-232 communication.
7.1.1 RS-232 Interface
The control commands for the MT106-103 are in a simple ASCII
character format.
1. Square brackets “[ ]” are part of the command.
2. Use uppercase letters for all commands.
3. Spaces are NOT legal characters.
The cards in a MultiTasker are capable of performing various
functions, as well as providing feedback to the user or control s stem.
Commands instruct a card to perform specific actions or request
information from the card. Some commands do both simultaneousl .
A command that instructs the card onl to perform an action will
generate feedback of "[ ]". The open bracket immediatel followed b
a closed bracket indicates the card received a valid command. If the
command requested information from the card, the feedback
generated b the card is the acknowledgement of having received a
valid command. Invalid commands generate feedback that includes
"ERR" plus an error code.
Example 1: [ERR001] Error number
Example 2: [ERRC04] Card error C4
After processing a command, an "OK" or error is returned as feedback
if "F" is included at the end of a command string.
Commands ending in "S" will be saved into memor . Commands not
ending in "S" are executed, but not restored at reset or powered-up.
7.1.2 Conventions Used in this Manual
Card IDs:
In this manual, cards are referenced b their card ID; t picall
equivalent to the slot number:
C1, C2, C3, C4 ... C99
Group IDs:
Groups are referenced b their group ID:
G1, G2, G3 ... G8
Unit IDs:
Units are referenced b their unit ID:
U0, U1, U2 ... U20
Examples for each command in the following sections do not
include the unit ID. Commands sent to a MultiTasker without a
unit ID are executed b all MultiTaskers connected to the
RS-232 bus. It is onl necessar to include the unit ID when
there is more than one MultiTasker connected to the bus and
the command is intended for cards in that MultiTasker onl .
[VERC3]: Executed b all MultiTaskers on the RS-232 bus.
[VERC3U1]: Executed b MultiTasker unit ID U1 onl .
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 (optional for Unit ID 0)
For Function, see a detailed explanation under each description.
The card ID is a unique identifier. It is equal to the enclosure slot
number, or it ma be an assigned value. As the slot number, the value
can range from 1-4 up to 1-20 depending on the enclosure. If the value
is assigned, the ID ma be a maximum of 99. Card ID 0 (C0) is used for
the controller and cannot be reassigned.
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
perform the given instruction.
Changing the position of a card significantl affects the commands
recorded on software definitions or third-part control s stems.
Example:
[VERC3]: For U0 or all MultiTaskers on the bus.
[VERC3Ui]: For IDs other than U0 or all MultiTaskers.
[VERC3]: Equivalent to [VERC3U0] for U0.
Command Organization
The RS-232 commands in this section are organized into the following 5
categories:
Basic Commands
Feedback Control
Card Control
Card IDs
Groups
See the SUMMARY OF COMMANDS (Section 7.3) for one-line

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
14. […S] – SAVE
This command will save the configuration command being sent in
memor . When sending the command [I1O1C4S], after reset or
power up, Input 1 will be connected to Output 1 on C4. This
command onl saves the Input 1 to Output 1 connection above. In
order to save all the current settings, use the [CnS] command.
15. […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.
16. […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 immediatel . 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 MT105-120 in slot 4. Currentl , 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.

17. [SW] – SWITCH
This command immediatel connects inputs and outputs previousl
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.

[I1O1C4]. Input 1 is not connected to Output 1.
19. [IO*]
This command will connect a single input with all outputs. It will not
affect the ON/OFF status of the output.
Command Format: [IxO*CnUi]
x = Input (x = # from 1 to max inputs)
Cn = Card ID (n = # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)
Example:

23. [FBD]
This command turns feedback dela on or off. It is necessar when
installing some newer cards in older s stems. If the s stem does not
receive all of the feedback from the card, the card ma be
communicating too fast. This command will slow down the card's
communication rate.
Command Format: [FBDmCnUi]
m = Dela (0= no dela , 1= dela 100mS)
Cn = Card ID (n = # from 1 to max slots)
Ui = Unit ID (i = from 0 to 9)
Example:
The command [HELPC4] is sent to the card in slot 4. Some of the
HELP file is displa ed on the screen, but most is missing. Send the
command [FBD1C4] to slow down the rate at which the card sends
feedback to the s stem.
ID Commands
The default card ID is the same as the card slot number. The next several
commands allow the user to change the card ID to a value other than the
slot number. Once the ID is changed, moving the card to another slot will
not change the card ID. If a card in slot 4 is set to ID 1, then moved to slot
10, its ID will remain 1. The [RSI] command forces each installed card to
take its slot number as its ID number, regardless of the slot in which it is
installed.
Some cards require more than one slot in the MultiTasker s stem. As an
example, some matrix switcher cards require 4 slots. If 5 of these cards are
installed, the would be numbered C4, C8, C12, C16, and C20. Changing
the ID allows the user to define the cards as C1, C2, C3, C4, and C5.
Another use for changing the card ID is to be able to use multiple s stems
without having to set each unit to a different unit ID. All s stems ma be
left as unit ID 0 for ease of programming. The cards in the first unit ma be
numbered 1-10 and in the second unit 11-20.
24. [RSI]
This command resets the card IDs in the s stem. After sending this
command, each card ID in the s stem will match the slot number of
the card. If the card is moved to another slot, its ID number will be the
new slot number.
Command Format: [RSI]
Example:
Send the command [RSI] to the s stem with Unit ID 0. The card in
slot 1 will have ID 1, the card in slot 2 will have ID 2, and so on. If the
card in slot 1 is then moved to slot 4, the card ID will then be 4.
25. [SIDn]
This command sets all the cards installed in the MultiTasker s stem to
the same card ID. After sending this command, all cards will be
addressed with the same ID. Use caution when sending this command
to a s stem with multiple board t pes.
Command Format: [SIDn]
n = Card ID (n = # from 1 to 99)
Example:
Send the command [SID1] to the s stem. All the cards in the s stem
now have ID 1. An commands that are sent to card ID 1 will be
received and executed b each card.
26. [SIDnCi]
This command sets the card ID of a single card to a number from 1 to
99.
Command Format: [SIDnCi]
n = Card ID (n = # from 1 to 99)
Ci = Slot Number (i = # from 1 to max slots)
Example:
Send the command [SID50C10] to set the ID of the card in slot 10 to
an ID of 50.
27. [SID+]
This command sets the card ID of all the cards in a s stem to their slot
number plus the offset value.
Command Format: [SID+n]
n = Offset amount (n = # from 0 to 99)
The maximum card ID is 99, so subtract the highest slot
number from 99 to find the maximum offset. For example, in
an 8-slot enclosure, the maximum offset would be 91. The
slot number (8) plus the offset (91) equals 99.
Example:
There are two 20-slot enclosures to be connected together during
normal operation. The first unit will use the default IDs where the
card ID is equal to the slot number. The second unit will have the
same unit ID, but each card ID will be offset b 20.
Connect the computer to the second unit onl and send the command
[SID+20] to set the ID of all the cards in the second enclosure to their
slot number plus 20. Reconnect both units to the computer.
The cards in the first unit will be referenced as card IDs 1-20 and the
cards in the second unit will be referenced b card IDs 21-40.

28. [RSN]
This command displa s the slot number of a card with a specified ID
number. If more than one card has the same ID, each slot number will
be displa ed.
Command Format: [RSNCi]
Ci = Card ID (i = # from 1 to 99)
Example:
The card in slot 4 takes up four slots in the enclosure. Its ID was set to
1 since it is the first card installed in the s stem, reading from left to
right. Send the command [RSNC1] to find the slot number of this card.
The s stem responds with the following feedback:
[4]
29. [HELP]
This command displa s information available for the MultiTasker interface
commands.
Command Format: [HELPCnUi]
Cn = Card ID (n = # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)
Example:
In order to displa the RS 232 commands available for the MT105-
120/121 card in slot 2, send the command [HELPC2]. The commands
along with a brief description will be displa ed in the Terminal
Window.
Group Commands

Gk = Group ID (k = # from 1-8)
Example:
Add C2, C4, and C6 to G5 b sending the command [WRC2C4C6G5].
After executing this command, G5 will consist of C2, C4, and C6.
Now add C8 to G5 b sending [WRC8G5]. C8 is added to G5, and G5
is not overwritten. View the contents of G5 b sending [RDG5] and
receiving the following feedback:
[G5=C2C4C6C8]
31. [RMC]
This command removes one or more cards from a group.
Command Format: [RMCn 1 Cn 2 …Gk]
Cn = Card ID (n= # from 1 to max slots)
Gk = Group ID (k = # from 1-8)
Example:
G5 consists of C2, C4, C6, and C8. Remove C6 and C8 b sending
[RMC6C8G5]. View the contents of G5 b sending [RDG5] and
receiving the following feedback:

sending [RMG * ]. The s stem will return the following feedback:
G1-G8: EMPTY
33. [RD]
This command reads and then displa s the members in a group.
Command Format: [RDGk]
Gk = Group ID (k = # from 1-8)
Example:
C2, C4, and C6 make up G5. Read the member data for G5 b sending
the command [RDG5]. The s stem will return feedback as follows:
[G5=C2C4C6]
The feedback shows G5 and then the cards that make up G5. In this
case, G5 includes C2, C4, and C6.

7.4 Menu Mode
MENU MODE commands are RS-232 commands that allow virtuall the
same functionalit 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 s stem then responds
based upon selections made b the user.
MENU commands ma be issued in response to prompts from within
MTSetup™ or other RS-232 communication software.
The MENU driven commands are onl available with MultiTasker Front
Panel s stems 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 s stem 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 displa ed in the
menu mode, but the automatic feature will displa after each setting
change making the menus difficult to read.
1. In order to enter menu mode, the s stem needs to be connected to a
computer running RS-232 control software.
2. In the terminal window, press ENTER on the ke board.
3. The s stem interrogates all cards and returns a list of cards and their ID
numbers.
Example: 08: MT105-120
NOTE: Onl cards supporting the menu feature will be displa ed.
4. Enter the two digit ID and a menu for the card will be displa ed. In
the example above, enter “08” for the MT105-120.
WARNING: Do NOT enter an characters except those relating to the
desired menu. Press ENTER after "08" and the original prompt will be
displa ed.
5. After selecting the MT105-120 as described above, the s stem will
prompt for selections specific to that card.
6. Read each menu carefull , and continue selecting ke s as prompted for
further functions. (Example prompt: "Ke = ")
7.4.3 Menu Types
1. Main Menu
The first menu displa ed after selecting the card is the Main Menu.
This menu provides access to the ke functions related to the card.
Press the ke representing the menu item for access and a sub menu
will appear.
2. Sub Menus
Each menu item will displa either a sub menu, or a list of options.
Press the ke corresponding to the desired choice.
7.4.4 MT105-120/121 Menus
Following are the menus available to the MT105-120/121. The first menu
is the Main Menu onl . 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 onl 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 repeatedl will toggle Output 1 ON
and OFF.
S stem 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 s stem will respond with "ok."
Entering "S" will redispla the connection settings.
The S nc Dela menu will prompt the user to select the output number for
dela . After that, the s stem will displa a one line prompt so the user can
enter the S nc Dela value.
CAUTION: Pa 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 ma be
modified from this menu, make sure the desired card or group is selected.

MT105-120/121; however, we would like to offer suggestions for the
following:
8.1 Card is not recognized
Cause 1: The card is not recognized.
Solution: Reset the card cage b sending the [RES] command, or turning
the s stem power off, and then on. Send the [C] command to
see if there is communication with the card. If there is no
feedback, see Cause 2.
Cause 2: Card is not plugged in all the wa .
Solution: Push the card in all the wa . Reset the s stem and send the [C]
command. If the card is still not recognized, see Cause 3.
Cause 3: Card cage slot has a problem.
Solution 1: Test the card in other slots of the card cage. If the slot was
damaged, the card ma work in other slots. If other slots work
and the card is recognized, the problem is the card cage slot.
The card cage ma require service. Call ALTINEX at (714) 990-
