ABOUT YOUR MT103-122 2
MT103-122
VIDEO + AUDIO TO TWISTED PAIR
TRANSMITTER CARD
The MT103-122 provides a means of transmitting
computer video and audio signals over Twisted
Pair-type (CAT-5) cable when used together with
an ALTINEX Twisted Pair Video Receiver, such as
the MT103-123 or DA1931CT.
The MT103-122 is compact and easy to use. The
MT103-122 is able to transmit any one of the video
sources, such as RGBHV, YPbPr, S-Video or
C-Video and stereo audio over CAT-5 cable.
The MT103-122 offers a 15-pin HD female
connector with the native Plug &Play compatibility
for computer video, a 4-pin Mini DIN connector for
S-Video input, and an RCA connector for C-Video
input. The 3.5 mm jack is used for unbalanced
stereo audio input. The RJ-45 female connector
provides the output to the Twisted Pair cable.
The MT103-122 features signal detection and video
equalization. Signal Detect shows when a signal is
present and provides feedback over the RS-232
bus. Video equalization provides for transmission
lengths up to 400 ft (122 m). Longer runs are
possible if the receiver has video equalization. The
card may be preset to allow for either software or
hardware control of equalization. There is also
hardware gain control for the audio output.
The latest generation of Twisted Pair devices uses
an innovative, patented technology* developed by
ALTINEX. The new signal processing technology
allows transmitting and receiving fully equalized
computer video signals, stereo, and audio signals
over long distances. The maximum distance at full
UXGA resolution is 400 ft (122 m) between devices
and may reach up to 750 ft (230 m) at VGA
resolution.

INSTALLING YOUR MT103-122 6
Step 1. Determine the settings required for Audio
Sync and Equalization. See Diagram 4 for
Switch Settings.
Step 2. Turn off power to the MultiTasker and
disconnect AC power.
Step 3. Remove a slot cover (MT200-101) from
one of the unused slots. Identify the slot
number and note that it is for RS-232
control.
Step 4. Slide the MT103-122 into an available slot
in the MultiTasker enclosure in order to
connect it to the bus. Make sure that the
card fits into place. Secure the card to the
MultiTasker by tightening the retainer
screws located on the top and bottom of
the card.
Step 5. Restore power to the enclosure and verify
the LED near the top of the card is on and
red indicating power is applied.
Step 6. Connect one of the following video
sources to the MT103-122 input:
RGBHV/YPbPr, S-Video,or C-Video.
Verify the LED turns green if using an
RGBHV signal.
Step 7. Connect the audio source to the AUDIO
INPUT jack.
Step 8. Connect aCAT-5/6 cable from the video
output of the MT103-122 Transmitter to
the Twisted Pair input port on the
MT103-123 or equivalent receiver.
Step 9. Verify the picture quality on the receiving
monitor is equivalent to the quality as
displayed on a local monitor. If the quality
of the image is poor or non-existent, it
may be necessary to adjust the video
equalization on the MT103-122 and/or
MT103-123. If hardware-controlled, adjust
using the knob on the panel; for software
control see the [EQ] command in the
OPERATION section of this manual.
OPERATION 7
7.1 RS-232 CONTROL
The MT103-122has many advanced
remote-control capabilities accessible through
standard RS-232 communication. Control may be
accomplished through a computer control system
or any other device capable of sending RS-232
communication.
7.1.1 RS-232 INTERFACE
The control commands for the MT103-122 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 system 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 about the
status of 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
closedbracket 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 of “[ERR001]”.
After processing a command, an “OK” or
[ERR001] 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.

MULTITASKER
400-0373-00310
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-to-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. When
using the group ID, all cards in the group will
perform the given instruction.
NOTE: In this manual, cards will be referenced
by their ID (C1, C2...C99). Typically, the ID
number will be equivalent to the slot number.
Groups will be referenced by their ID (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 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]
COMMANDS

Sending the command [C10] to the MultiTasker
will yield the following feedback:
ON, EQ=0 C10
ON = output is on
EQ=0 = equalization is zero
C10 = card ID
If there is no card in slot 10, sending the
command [C10] 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 then back on, the card restores
the saved settings.
Cn = Card ID

[C10S]. The feedback returned will be similar to
the following:
ON, EQ=0 C10 [SAVED]
FEEDBACK COMMANDS
The next four commands are a function of both
the card and the front panelfirmware.
4. [?]
This command displays general information
about the MultiTasker and cards installed in the
unit.
Command Format: [?Ui]
Ui = Unit ID (i = from 0 to 9)
Example:
A MultiTasker with ID 1 has a front panel with
part number MT101-101 and contains an
MT103-122 and an MT103-123. Send the
command [?U1] and receive the following
feedback:
[(MT101-101U1)(MT103-122C10)
(MT103-123C19)]
MT101-101U1 = Panel model/unit ID
MT103-122C10 = An MT103-122 is in slot 10
MT103-123C19 = An MT103-123 is in slot 19
5. [?C]
This command will display general information
about the card and its status.
Command Format: [?Cn]
Cn = Card ID (n = # from 1 to max slots)
Example:
The MT103-122 in slot 10 has a software
equalization value of 25 and the output is
enabled. Send the command [?C10] to receive
feedback status similar to the following.
[(MT103-122C10)(VR690-0197-005C10)
(ONC10)(EQ25C10)(SI0C10)]
All status feedback is enclosed in brackets, “[ ]“.
Each data field within the status is enclosed in
parentheses. The first two characters identify
the status type. The last three characters are the
card’s ID.
MT103-122 = Card model number
VR690-0197-005= Firmware version
ON = Output status
EQ25 = Video equalization
SI0 = Input signal status
The output status line always reads“ON” since
the MT103-122 does not have an output disable
feature.
The software video equalization value is shown
following the EQ prefix, or 25 out of 50.
The input signal detect line will display a “1”
following the SI prefix if an input signal is
detected, otherwise a “0” will follow the prefix.
6. [STA1]
This command enables automatic feedback
from the front panel. The command affects any
card with auto-feedback capability, not just the
MT103-122. The default at power on or reset is
STA0, off. For more details, see the [?Cn]

SETUP COMMANDS
8. [SIG]
This command will test for the presence of an
input signal and return a “1” if a signal is present
and return a “0” if no signal is present.
Command Format: [SIGCn]
Cn = Card ID (n = # from 1 to max slots)
Example:
An MT103-122 is in slot 10 and there is a valid
Twisted Pair signal on the input. Send the
command [SIGC10] and the system will return
the following feedback:
1
9. [EQ]
This command displays the current software
equalization setting and selects the equalization
function for adjustment using the [+] and [-]
commands. This command has no effect if the
equalization switch is set for hardware control.
Command Format: [EQCn]
Cn = Card ID (n = slot # from 1 to max slots)
Example: DISPLAY EQUALIZATION
An MT103-122 card is in slot 10 and its
equalization level is set to zero. Send the
command [EQC10] and receive the following
feedback:
EQ=0
Example: ADJUST EQUALIZATION
Continuing from the previous example, the
equalization function is now active and may be
adjusted using the [+] and [-] commands. The
card will display the new equalization setting
after each [+] or [-] command. Send the
following commands to increase the equalization
to a value of 5:
[ +][ +][ +][ +][ +][ -]
EQ=1 EQ=2 EQ=3 EQ=4 EQ=5 EQ=6
The level is now 5and no further adjustments
are required.
10. [+]
See the [EQ] command for details.
11. [-]
See the [EQ] command for details.
12. [EQ=]
This command is used to set the equalization to
an absolute value and select the equalization
function for adjustment using the [+] and [-]
commands. This command has no effect if the
equalization switch is set for hardware control.
Command Format: [EQ=mCn]
m= Equalization (m =# from 0 to 50)
Cn = Card ID (n = slot # from 1 to max slots)
Example:
Set the equalization level of the MT103-122 card
in slot 10 to a value of 25 by sending the
command [EQ=25C10]. The [+] and [-]
commands may be used to fine-tune the
equalization at this time.
13. [CLR]
This command clears the card settings and sets
the software equalization to zero.
Command Format: [CLRCn]
Cn = Card ID (n = slot # from 1 to max slots)
Example:
Clear the MT103-122 by sending [CLRC10].

MULTITASKER
400-0373-00313
14. […S] –Save
This command will save the configuration
command being sent in memory. When sending
the command [EQ=10C10S], after reset or
power-up, the equalization level on C10 will be
set to 10.
15. [TEST]
This command performs a series of tests on the
internal memory. The system will display the
results and report any failures. If there are no
problems, the system will display the following:
MEMORY IS GOOD
Command Format: [TESTCn]
Cn = Card ID (n = slot # from 1 to max slots)
Example:
Test the internal memory of the MT103-122 in
slot 10 by sending the command [TESTC10].
16. [FBD]
This command turns feedback delay on or off
and 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: [FBDmCn]
m= Delay (0= no delay, 1= delay 100mS)
Cn = Card ID (n = # from 1 to max slots)
Example:
The command [HELPC10] is sent to the card in
slot 10. 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.
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.
The ID commands work with all MultiTasker
systems. However, front panels that have
firmware releases prior to the following will not
be able to address card IDs greater than the
number of slots in the system:
690-0122-019 = Version 019 or later.
690-0123-005 = Version 005 or later.
690-0124-019 = Version 019 or later.
Send the command [VER], and the system will
respond with feedback that includes the
following:
690-0122-019 690-0123-005 690-0124-019
Check the last three digits against the numbers
above to determine if the card ID commands
can address all 99 card IDs.

MULTITASKER
400-0373-00314
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.
20. [SID+]
This command sets the card ID of all the 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 sum of the slot number
(8) and the offset (91) is 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. 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 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:
[4]

MULTITASKER
400-0373-00315
22. [HELP]
This command displays information available for
the MultiTasker interface commands.
Command Format: [HELPCn]
Cn = Card ID (n = # from 1 to max slots)
Example:
Display the RS-232 commands available for the
MT103-122 in slot 10 by sending the command
[HELPC10]. The commands along with a brief
description will be displayed in the Terminal
Window.
GROUP COMMANDS
The next few commands are group commands.
The use of groups allows several cards with the
same functions to be controlled simultaneously
using a single command. Up to 8 groups
(G1-G8) may be defined in a MultiTasker
system. These commands apply to all cards,
not only the MT103-122.
23. [WR]
This command adds more cards to a group
allowing all the group members to be controlled
simultaneously with the same commands. Each
MultiTasker unit may define a maximum of eight
groups.
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 number (k = # from 1-8)
Example:
Add C2, C4, and C6 to G5by sending the
command [WRC2C4C6G5]. After executing this
command, C2, C4, and C6 will be G5. The
system will return the following feedback:
[G5=C2C4C6]
Now when a command is sent to G5, each
board in G5will execute the same command.
24. [RMC]
This command may be used to remove one or
more group members from a group. Reset the
system after using this command for all changes
to take effect.
Command Format: [RMCn1Cn2…Gk]
Cn = Card ID (n= # from 1 to max slots)
Gk = Group ID (k = # from 1-8)
Example:
G5 consists of the C2, C4, and C6. Remove
only C4 and C6 from the group by sending the
command [RMC4C6G5]. The system will return
the following feedback:
[G5=C2]
25. [RMG]
This command may be used to delete an entire
group, or all groups.
REMOVE A GROUP
Remove all the members from the group,
effectively deleting the group.
Command Format: [RMGk]
Gk = Group ID (k = # from 1-8)
Example:
G5 consists of the C2, C4, and C6. Remove all
cards from the group by sending the command
[RMG5]. The system will return the following
feedback:
[G5=0]

MULTITASKER

REMOVE ALL GROUPS
Remove all the members from every group,
effectively deleting all groups.
Command Format: [RMG*]
Example:
G5 consists of C2, C4,and C6. G2 consists of
C1, C2, C3, C4, and C5. Delete all the groups
by sending the command [RMG*]. The system
will return the following feedback:
G1-G8: EMPTY
26. [RD]
This command reads and then displays the
members in agroup.
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.
The menu-driven commands are only available with
MultiTasker systems that have the following front
panel firmware:
690-0122-015 = Version 015 or later.
690-0123-004 = Version 004 or later.
690-0124-018 = Version 018 or later.
Send the command [VER] and the system will
respond with feedback that includes 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.
7.4.1 MENU COMMAND DEFINITIONS
Refer to section 7.2 for details on card functions
and examples. Following is a cross-reference of
menu mode sections versus programming
commands.

7.4.2 USING MENU MODE
SUGGESTION: It is best to disable the
automatic feedback feature, [STA0]. The
automatic feature will display after each setting
change making the menus difficult to read.
1. In order to enter Menu Mode, the system
needs to be connected to a computer
running RS-232 control software.
2. In the Terminal Window, press ENTER on
the keyboard.
3. The system interrogates all cards and
returns a list of cards and their ID numbers.
Example: 08: MT103-122
NOTE: Only cards supporting the menu
feature will be displayed.
4. Enter the 2-digit ID and a menu for the card
will be displayed. In the example above,
enter “08”for the MT103-122.
WARNING: Do NOT enter any characters
except those relating to the desired menu.
Press ENTER after “08”and the original
prompt will be displayed.
5. The system will prompt for selections
specific to the selected card.
6. 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 key functions related to the
card. Press the key representing the menu
item for access and a sub-menu will appear.
2. SUB-MENUS
Each menu item will display either a
sub-menu, or a list of options. Press the key
corresponding to the desired choice.
7.4.4 MT103-122 MENUS
Following are the menus available to the
MT103-122. The first menu is the Main Menu
only. The second listing is an expanded view of
the card’s sub-menus.
The expanded menu contains values in
parentheses indicating the current setting or
value of the parameter. In some areas,
additional comments are provided for
clarification.

7.5 ADJUSTMENTS
The MT103-122 requires only two adjustments to
be made for optimal performance. The first is video
equalization for long cable lengths and the second
is audio gain for volume control of the main output.

MULTITASKER
400-0373-00319
7.5.1 VIDEO EQUALIZATION
Video equalization is provided to fine-tune the
displayed image on the remote display.
Typically, for short cable runs the equalization
will be set to near minimum. Cable lengths up to
400 ft (122 m) will require near maximum
equalization.
The equalization adjustmentson the
MT103-122 and MT103-123 cards work together
for maximum cable lengths. For example, for
cable runs less than 50 ft (15 m), both
equalization settings may be set to
approximately minimum, since on the short
distances no equalization is required. Cable
runs of 400 ft (122 m) will see equalization
settings at about the three-quarter position.
The equalization can be adjusted either from the
potentiometer located on the card’s panel or
through RS-232 control. See the installation
section for details.
7.5.2 AUDIO GAIN
Normally, the Audio Gain control on the
MT103-122will be set to maximum. When set to
maximum, the transmitted volume will be
equivalent to the volume from the audio source.
If necessary, the transmitted volume may be
reduced as required by the user.
TROUBLESHOOTING GUIDE 8
We have carefully tested and have found no
problems in the supplied MT103-122. However, we
would like to offer suggestions for the following:
8.1 LED IS NOT RED
Cause 1: There is no power.
Solution: Make sure the enclosure has power
applied and is turned on. If the LED
is still not on, see Cause 2.
Cause 2: The card is not recognized.
Solution: Reset the card cage by sending the
[RES] command or turning the
system power off and then back on
again. Send the [C] command to see
if there is communication with the
card. If there is no feedback, see
Cause 3.
Cause 3: The card is not plugged in.
Solution: Push the card in all the way. Reset
the system and send the [C]
command. If the card is still not
recognized and the LED is not on,
see Cause 4.
Cause 4: 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 may work in other slots. If
other slots work, the problem is the
card cage slot. The card cage may
require service. Call ALTINEX at
[phone]. If the other slots do
not work, see Solution 2.
Solution 2: Take any other known good card
and verify that the slot used is good
by seeing if the other cardis
recognized in that slot. If it is, then
the original card may be the source
of the problem. Call ALTINEX at
[phone].
8.2 LED IS NOT GREEN
Cause 1: There is no power.
Solution: Disconnect the video input from the
MT103-122 and verify the LED is on
and red indicating power is present.
Reconnect the computer's video
output. If the LED is still not green,
see Cause 2.
