INSTALLING YOUR MT115-111 6
Step 1. Determine the appropriate switch settings
using DIAGRAM 3 on page 8.
Step 2. Turn off power to the MultiTasker system
and disconnect from AC power.
Step 3. Remove an unused slot cover
(MT200-101). Identify the slot number and
note that it is for RS-232 control.
Step 4. Slide the MT115-111 into the enclosure in
order to connect it to the bus. Make sure
that the card fits into place and secure the
card by tightening its retainer screws.
Step 5. Restore power to the MultiTasker
enclosure. The LEDs for each input
should be on and red.
Step 6. Connect the computer/component video
and audio devices to Outputs 1 and 2.
Step 7. Connect the 4TP IN1 to the output of its
Twisted Pair transmitter. If a properly
formatted input signal is available, the
input LED will turn green.
Step 8. Connect the 4TP IN2 to the output of its
Twisted Pair transmitter. If a properly
formatted input signal is available, the
input LED will turn green.
Step 9. The MT115-111 is ready for operation.
Step 10. Video equalization is provided to fine-tune
the displayed image on the remote
display. The equalization adjustments on
the MT115-111 and Twisted Pair
transmitter work together. Adjust
equalization by setting both the
transmitter and receiver to minimum. Then
slowly increase the equalization on the
receiver until an image is present. Then
adjust the equalization on both units for
the best image.
Step 11. The MT115-111 also has video gain
adjustment capability through RS-232
control. See the following section for
RS-232 command details.
OPERATION 7
7.1 RS-232 CONTROL
The MT115-111 has many advanced
remote-control capabilities accessible through
standard RS-232 communication. Control may be
accomplished through a computer, control system,
or any device capable of RS-232 communication.
7.1.1 RS-232 INTERFACE
The control commands for the MT115-111, 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
system. Commands instruct a card to perform
specific actions or request information from the
card. Some commands do both simultaneously.
A command that instructs the card only to
perform an action will generate feedback of “[ ]”.
The open bracket immediately followed by a
closed bracket indicates the card received a
valid command. If the command requested
information from the card, the feedback
generated by 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
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 (optional for Unit ID 0)
For Function, see a detailed explanation under
each command description.
The card ID is a unique identifier. It is equal to
the enclosure slot number, or it may 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 may
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. W hen
using the group ID, all cards in the group will
perform the given instruction.
NOTE: In this guide, cards are referenced by
their IDs (C1, C2...C99). Typically, the ID
number will be equivalent to the slot number.
Groups will be referenced by their IDs (G1-G8).
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 range from U0 to U20. U0
should be used for single unit operation. If the ID
is set to U0, each command may be used
without Ui. Use the command [SETU0], as
explained in the MT101-101 User’s Guide.
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 descriptions of each command.
BASIC COMMANDS
The basic commands are used to provide general
information about the card. These commands are
most useful during the initial stages of setting up
and operating the card.
1. [VER]
This command displays the software version
and card type for the MT115-111 card.
Command Format: [VERCn]
Cn = Card ID (n = slot # from 1 to max slots)
Example:
An MT115-111 card is in slot 4. Send the
command [VERC4], and the system will return
feedback similar to the following:
[MT115-111 690-0231-001 C04]
MT115-111 = Card model number
690-0231-001 = Firmware version
C04 = Card ID
Example:
[VERC3]: For U0
[VERC3Ui]: For ID other than U0
[VERC3]: Equivalent to [VERC3U0]

MULTITASKER
2. [C]
This command receives the status of the card.
Command Format: [Cn]
Cn = Card ID (n = # from 1 to max slots)
Example:
There is one MT115-111 card in slot 4. Sending
the command [C4] to the system will yield
feedback similar to the following:
INPUT#1 VIDEO GAIN 4
EQUALIZATION 32
INPUT#2 VIDEO GAIN 4
EQUALIZATION 32
In this case, both card inputs are set for a video
gain of 4 and an equalization of 32.
If there is no card in slot 4, sending the [C4]
command will not return any feedback.
3. [CnS]
This command saves the card settings and
displays the status. After the system is reset or
powered off and on, the settings are restored.
Cn = card number
5. [CLR]
This command clears the card settings and
returns it to the factory default values. The
defaults gain setting is 4 and the default
equalization setting is 32 for each input.
Command Format: [CLRCn]
Cn = Card ID (n = slot # from 1 to max slots)
Example:
In order to clear the card in slot 4, send the
command [CLRC4]. The card will respond with
the following feedback when complete:
FACTORY RESET COMPLETED
6. [TEST]
This command performs a series of tests on the
internal memory and displays a pass message if
successful. Otherwise, failures are indicated.
Command Format: [TESTCn]
Cn = Card ID (n = slot # from 1 to max slots)
Upon completion, the system will display the
results. This feedback will be similar to the
following:
S = save configuration
Example:
Save the status by sending [C4S]. The
feedback returned will be similar to the following:
INPUT#1 VIDEO GAIN 4
EQUALIZATION 32
INPUT#2 VIDEO GAIN 4
EQUALIZATION 32
SAVED
4. [...S]
This command will save the configuration
command being sent in memory. When sending
the command [EQ1=16C4S], after reset or
power up, the equalization for Input 1 will be set
to 16.

7. [HELP]
This command displays information available for
the MultiTasker interface commands.
Command Format: [HELPCn]
Cn = Card ID (n = # from 1 to max slots)
Example:
In order to display the RS-232 commands
available for the MT115-111 card in slot 4, send
the command [HELPC4]. The commands along
with a brief description will be displayed in the
Terminal Window.
11
MULTITASKER
FEEDBACK CONTROL
The next commands are a function of both the card
and the front panel and allow flexibility over when
and how card information is displayed.
8. [FBD]
This command turns feedback delay on or off. It
is necessary when installing some newer cards
in older systems. If the system does not receive
all of the feedback from the card, the card may
be communicating too fast. This command will
slow down the card's communication rate.
Command Format: [FBDm]
m = Delay (0= no delay, 1= delay 100mS)
Example:
The command [HELPC4] is sent to the card in
slot 4. Some of the HELP file is displayed on the
screen, but most is missing. Send the command
[FBD1] to slow down the rate at which the card
sends feedback to the system.
9. [?]
This command will return general information
about the MultiTasker and cards installed in the
unit.
Command Format: [?Ui]
10. [?C]
This command will return general information
about the card and its status.
Command Format: [?Cn]
Cn = Card ID (n = # from 1 to max slots)
Example:
The MT115-111 in slot 4 has Inputs 1 and 2 set
to their default values. Send the command [?C4]
to receive feedback similar to the following.
[(MT115-111C04) (VR690-0231-001C04)
(GN0404C04) (EQ3232C04)]
All feedback is enclosed in square brackets.
Each data field in the status is in parentheses.
The first two characters identify the status type
and the last three are the card’s ID.
MT115-111 = Card model number
VR690-0231-001 = Firmware version
GN0404 = Video gain levels
EQ3232 = Equalization settings
The video gain levels are displayed for both
Input 1 and Input 2. The first 2 digits are the
setting for Input 1 and the last 2 digits are the
setting for Input 2. In this case, both are set to a
level of 4 out of 11.
Ui = Unit ID (i = from 0 t o 9)
Example:
A MultiTasker with unit ID 1 has a front panel
with part number MT101-101 and contains an
MT103-122 and MT115-111. Send the
command [?U1] and receive the following:
[(MT101-101U1)(MT103-122C01)
(MT115-111C04)]
MT101-101U1 = Panel number/unit ID
MT103-122C01 = MT103-122 is in slot 1
MT115-111C04 = MT115-111 is in slot 4
400-0443-004
The equalization levels are displayed for both
Input 1 and Input 2 as well. The first 2 digits are
the setting for Input 1 and the last 2 digits are
the setting for Input 2. In this case, both are set
to a level of 32 out of 64.
11. [STA1]
This command enables automatic feedback
from the front panel. The command affects any
card with auto-feedback capability, not just the
MT115-111. The power on default or reset is
STA0, off. For more details, see the [?Cn]

not just the MT115-111. The default at power
on or reset is STA0, OFF.
Command Format: [STA0]
13. [EQ]
This command displays the equalization setting
for an input and selects that input for adjustment
using the [+] and [-] commands.
Command Format: [EQmCn]
m = Input # (m = 1 or 2)
Cn = Card ID (n = slot # from 1 to max slots)
Example:
Display the equalization setting for Input 1 of C4,
then increase the equalization level by 3 from a
starting value of 12.
Send the command [EQ1C4] and the current
setting for Input 1 will be displayed.
[12]
Next, send the commands [+], [+], and [+] to
increase the setting by 3. Send the [EQ]
command again to receive new value.
[15]
CARD CONTROL
Card control commands allow the main functions of
the card to be executed over the RS-232 bus, or
from the front panel’s programmable keys.
14. [EQ=]
This command sets the equalization for an input
to a value specified by the user.
Command Format: [EQm=xCn]
m = Input # (m = 1 or 2)
x = Equalization level (m = # from 1 to 64)
Cn = Card ID (n = slot # from 1 to max slots)
Example:
Set the equalization on Input 2 of C4 to a value
of 32 by sending the command [EQ2=32C4].
The card will respond with feedback of “[ ]” once
the command is executed.
15. [GAIN]
This command displays the gain setting for an
input and selects that input for adjustment using
the [+] and [-] commands. A gain setting of 4 is
equivalent to unity gain.
Command Format: [GAINmCn]
m = Input # (m = 1 or 2)
Cn = Card ID (n = slot # from 1 to max slots)
Example:
Display the gain setting for Input 2 of C4, then
decrease the gain level by 3 from a starting
value of 10.
Send the command [GAIN2C4] and the current
setting for Input 1 will be displayed.
[10]
Next, send the commands [-], [-], and [-] to
decrease the setting by 3. Send the [GAIN]
command again to receive new value.
[7]
400-0443-004
13
MULTITASKER
16. [GAIN=]
This command sets the gain level for an input to
a value specified by the user. A gain setting of 4
is equivalent to unity gain.
Command Format: [GAINm=xCn]
m = Input # (m = 1 or 2)
x = Gain level (m = # from 1 to 11, 4 = unity)
Cn = Card ID (n = slot # from 1 to max slots)
Example:
Set the gain level for Input 2 of C4 to a value of
4 by sending the command [GAIN2=4C4]. The
card will respond with feedback of “[ ]” once the
command is executed.
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 system. As an example, some matrix
switcher cards require 4 slots. If 5 of these cards
are installed, they 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 systems without having to set each
unit to a different unit ID. All systems may be left as
unit ID 0 for ease of programming. The cards in the
first unit may be numbered 1-10 and in the second
unit 11-20.
17. [RSI]
This command resets the card IDs in the
system. After sending this command, each card
ID in the system 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 system 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.
18. [SIDn]
This command sets all the cards installed in the
MultiTasker system 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 system with multiple
board types.
Command Format: [SIDn]
n = Card ID (n = # from 1 to 99)
Example:
Send the command [SID1] to the system. All the
cards in the system now have ID 1. Any
commands that are sent to card ID 1 will be
received and executed by each card.
19. [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.
400-0443-004
14
MULTITASKER
20. [SID+]
This command sets the card ID of all cards in a
system 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 by 20.
Connect the computer to the second unit only
and send the command [SID+20] to set the ID of
all the cards in the second enclosure to their slot
number plus 20, then reconnect both units.
The cards in the first unit will be referenced as
card IDs 1-20 and the cards in the second unit
will be referenced by card IDs 21-40.
21. [RSN]
This command displays 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 displayed.
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 system, reading from left to
right. Send the command [RSNC1] to find the
slot number of this card. The system responds
with the following feedback:
GROUP COMMANDS
Group commands allow several cards with the
same functions to be controlled simultaneously with
a single command. Up to 8 groups (G1-G8) may be
defined. These commands apply to all cards, not
only the MT115-111.
22. [WR]
This command adds cards to a group. In
MultiTasker systems with audio and video cards,
the groups are typically as follows:
Group 1 = Video Cards
Group 2 = Audio Cards
Group 3 = Video and Audio Cards
Command Format: [WRCn1Cn2…Gk]
Cn = Card ID (n = slot # from 1 to max slots)
Gk = Group ID (k = # from 1-8)
Example:
Add C2, C4, and C6 to G5 by sending the
command [WRC2C4C6G5]. After executing this
command, G5 will consist of C2, C4, and C6.
Now add C8 to G5 by sending [WRC8G5]. C8 is
added to G5, and G5 is not overwritten. View
the contents of G5 by sending [RDG5] and
receiving the following feedback:
[G5=C2C4C6C8]
23. [RMC]
This command removes one or more cards from
a group.
Command Format: [RMCn1Cn2…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 by sending [RMC6C8G5]. View the
contents of G5 by sending [RDG5] and receiving
the following feedback:

24. [RMG]
This command deletes one or all groups.
Command Format: [RMGk]
Gk = Group ID (k = # from 1-8, * for all)
Example:
Remove all cards from G52 by sending [RMG 5].
The system will return the following feedback:
[G5=0]
Example 2:
Remove all cards from all groups, effectively
deleting all groups, by sending [RMG*]. The
system will return the following feedback:
G1-G8: EMPTY
25. [RD]
This command reads and then displays 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 by sending the command [RDG5].
The system 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 allow virtually the same
functionality as programming commands. Unlike
the programming commands in the previous
sections, menu commands prompt the user to
select from a list of available options. The system
then responds based upon selections made by the
user.
7.4.1 MENU COMMAND DEFINITIONS
Refer to section 7.2 for details on card functions
and examples. Following is a cross-reference
between menu mode and programming
commands.
MENU COMMAND

needs to be connected to a computer
running RS-232 control software.
4. Enter the ID number of the desired system.
In the example above, enter a “1” for the
MultiTasker with unit ID 1.
5. The system then interrogates all the cards
available in its enclosure and displays a list
of available cards.
Example: 01: MT103-122
02: MT103-123
04: MT115-111
6. Enter the 2-digit ID and a menu for the card
will be displayed. In the example above,
enter “04” for the MT115-111.
7. The system will prompt for selections
specific to the selected card.
8. Read each menu carefully, and continue
selecting keys as prompted.

TROUBLESHOOTING GUIDE 8
We have carefully tested and found no problems in
the supplied MT115-111 unit. However, we would
like to offer the following suggestions:
8.1 LEDs ARE OFF Cause 1: There is no power to the card.
Solution 1: Make sure the card is plugged all
the way into the enclosure. If an
LED is still not on, see Cause 2.
Cause 2: The card is not initialized.
Solution 1: Turn the system power off and then
back on again. If one of the LEDs is
still not on, please call ALTINEX at
(714) 990-2300.
8.2 DISPLAY IS TOO BRIGHT Cause 1: The software gain is too high.
Solution: Set the gain control to 4 using the
RS-232 commands in Section 7.2. If
the display is still too bright, see
Cause 2.
Cause 2: The gain switch is not set
correctly.
Solution: Set the gain control switch to the
HW (hardware) position for a fixed
gain of one. If the display is still too
bright, see Cause 3.
Cause 3: The receiver video gain is too
high.
Solution: Set the gain control switch to the
HW (hardware) position for a fixed
gain of one. If the display is still too
bright, please call ALTINEX at
(714) 990-2300.

8.3 NO DISPLAY Cause 1: The source has a problem.
Solution: Check the source and make sure
that there is a signal present and all
source connections are correct. If
the source is working and there is
still no display, see Cause 2.
Cause 2: Signal is bad or missing.
Solution 1: Make sure the input is connected to
the TP transmitter. If there is still no
display, see Solution 2.
Solution 2: Bypass the MT115-111 and TP
transmitter and connect the output of
the source directly to the monitor. If
the display is good, then call
ALTINEX at (714) 990-2300. If there
is still no display, see Cause 3.
Cause 3: Cable connections are incorrect.
Solution: Make sure the cables are properly
connected. Also, make sure that the
continuity and wiring are good. If
there is still no display present, see
