ABOUT YOUR MT107-103 2

MT107-103

64 X 64 Audio Matrix Engine

The MT107-103 is a 64X64 Matrix Engine used for
connecting balanced audio signals. The Matrix
Engine has 8 balanced audio inputs and 8
balanced audio outputs built-in. Additional inputs
and outputs may be added using input and output
audio expansion cards. The expansion cards are
mounted to the engine with specially provided
cables.

The audio input signals are buffered to the matrix
switcher through individual differential line
receivers. The MT107-103 will accept balanced or
unbalanced inputs. The input preset and mute
controls may be applied to any individual input and
are software-controlled for flexibility.

All control of the Matrix Engine is maintained
through the MultiTasker enclosure. The engine
may be controlled using the RS-232 bus, or by
preprogramming the MultiTasker enclosure.
Programming the enclosure eliminates the need for
having an external computer to control the Matrix
Engine.

An audio signal detection circuit is present on all
inputs and outputs in order to make troubleshooting
easier. Each of the outputs is driven by a balanced
audio line driver. The output impedance is low and
is capable of driving signals into 600Ω, including
applications requiring long cable lengths.

The Matrix Engine may be easily configured to
meet customer requirements by selecting the
appropriate number of switching elements.
Selecting the proper configuration may be achieved
using AVSnap®or other control software. The
switching elements within the matrix switcher are
available in steps of 16 and made possible through
the modular design of the Matrix Engine.

INSTALLING YOUR MT107-103 6

Step 1. Determine the number of slots required

for the MT107-103, including the add-on
cards. The base MT107-103 requires two
slots, and a fully loaded 64X64 Matrix
Engine requires 16 slots.

Step 2. Turn off power to the MultiTasker system

and disconnect from AC power.

Step 3. Carefully, slide the MT107-103 into

available slots in the MultiTasker
enclosure in order to connect to the bus.
Make sure that the MT107-103 cards fit
into place.

Step 4. Secure the cards to the MultiTasker by

tightening the retainer screws located on
the top and bottom of each card.

Step 5. Connect a cable from an audio source to

one of the input connectors on the
MT107-103 and another cable from an
output connector to a receiving device.

Step 6. Starting from the left, identify the slot

number where the MT107-103’s Input
Connector Card is plugged into the
enclosure.

The Input Connector Card is the circuit
card on the left-hand side of the engine
as it is being installed. Make note of the
slot number. It is required for RS-232
control.

Step 7. Restore power to the MultiTasker system.
Step 8. The MT107-103 is now operational.

OPERATION 7

7.1 RS-232 CONTROL

The MT107-103 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 MT107-103 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
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: [ERR001]

400-0367-005 7

After processing a command, an “OK” or error
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

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. When
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.

Example:
[VERC3]: For U0

[VERC3Ui]: For ID other than U0
[VERC3]: Equivalent to [VERC3U0]

COMMAND ORGANIZATION
The COMMAND SUMMARY (Section 7.3) gives

one-line descriptions of each command.
Commands in this section are organized into 6
groups:

Basic Commands
Feedback Control
Matrix Setup
Card Control
Card IDs
Groups

NOTE: Large Command Blocks

Disable the MT107-103’s feedback prior to
sending more than 10 commands to the
card in a single burst with no delays
between characters or commands. See the

[AFB] command for details.
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 firmware version
and model number for the MT107-103 card.

Command Format: [VERCn]
Cn = Card ID (n = slot # from 1 to max slots)
Example:
There is an MT107-103 card in slot 8. Send the

command [VERC8] and card will return the
following feedback:

[MT107-103 690-0159-010 C08]
MT107-103 = the card model
690-0159-010 = the software version

400-0367-005 8

C08 = card ID number

MULTITASKER

2. [C]
This command displays the active matrix

configuration, input-to-output connections, and
output on/off status.

Command Format: [Cn]
Cn = Card ID (n = slot # from 1 to max slots)
Example:
There is an MT107-103 in slot 8. Send [C8] and

the card will return feedback in the following
format:

Matrix mode:non-blocking
Matrix number:1
Matrix size:64X64
Input offset:0
Output offset:0
Channel width:1
Channel space:0

OUT

1-8 : 1 1 1 1 1x 1x 1x 1x

9-16: 9x 10x 11x 12x 13x 14x 15x 16x
17-24: 17x 18x 19x 20x 21x 22x 23x 24x
25-32: 25x 26x 27x 28x 29x 30x 31x 32x
33-40: 33x 34x 35x 36x 37x 38x 39x 40x
41-48: 41x 42x 43x 44x 45x 46x 47x 48x
49-56: 49x 50x 51x 52x 53x 54x 55x 56x
57-64: 57x 58x 59x 60x 61x 62x 63x 64x

Description of Feedback:
The first line of the status shows the matrix in

non-blocking mode (see [MODE] command for
details). The next line lists the matrix number
followed by 5 lines that describe the properties
of the matrix. The second half of the status, the
remaining 8 lines, shows the input-to-output
connections and the output on/off status.

In the above example, Matrix 1 is the active
matrix and is configured as a 64X64 matrix with
no input or output offset. The channel width is 1,
and the channel spacing is 0, so each of the 64
inputs and outputs are switched individually.

The last 8 lines of the status are the connection
settings, and each output on/off status. The top
line shows the inputs that are connected to
Outputs 1-8 and the next line shows the inputs
that are connected to Outputs 9-16, and so on.
The lowercase “x” next to the input number
indicates that its output is turned off. In this
case, Input 1 is connected to Outputs 1-8,
Output 9 is connected to Input 9, Output 10 to
Input 10, and so on. Outputs 5-64 are turned
off.

3. [CnS]
This command saves the input-to-output

connections and on/off settings. This
configuration will be restored after the system is
reset or powered off, then back on.

Command Format: [CnS]
Cn = Card ID (n = # from 1 to max slots)
S = save configuration
Example:
Save the setup from the example in the previous

command by sending [C8S]. The feedback
would be as follows:

VIS:OFF
Matrix mode:non-blocking
Matrix number:1
Matrix size:64X64
Input offset:0
Output offset:0
Channel width:1
Channel space:0

OUT

1-8 : 1 1 1 1 1x 1x 1x 1x

4. […S] – Save
This command will save the configuration

command being sent in memory. Send the
command [I1O1C8S] to the engine. After reset
or power-up, Input 1 will be connected to
Output 1 of the engine in slot 8.

5. [SIO]
This command displays the logical

input-to-output connections and their status.
Command Format: [SIOCn]
Cn = Card ID (n = slot # from 1 to max slots)
Example:
Send the command [SIOC8] to the MT107-103

in slot 8 and the card will respond with feedback
similar to the following:

Ch1 In1 Out1 ON
Ch1 In1 Out2 ON
Ch1 In1 Out3 ON
Ch1 In1 Out4 ON
Ch1 In1 Out5 OFF
Ch1 In1 Out6 OFF
Ch1 In1 Out7 OFF
Ch1 In1 Out8 OFF
Ch1 In9 Out9 OFF

etc.

Ch1 In61 Out61 OFF
Ch1 In62 Out62 OFF
Ch1 In63 Out63 OFF
Ch1 In64 Out64 OFF

Notice that each input-to-output connection is
preceded by the channel number. For example,
“Ch1 In1 Out1 ON” indicates that channel 1 of
Input 1 is connected to channel 1 of Output 1. If
the matrix is configured with multiple channels,
each channel is displayed on its own line. For
example, if each input and output had 2
channels, the display would be:

6. [CLR]
This command resets the MT107-103 to the last

saved matrix configuration. It does not affect the
blocking mode or VIS settings.

Command Format: [CLRCn]
Cn = Card ID (n = slot # from 1 to max slots)
Example:
Clear the MT107-103 with engine card in slot 8

by sending [CLRC8].

7. [TEST]
This command performs a series of internal

tests on the matrix engine memory.
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, otherwise failures will be indicated.

MEMORY IC TEST RESULTS:
MEMORY IC PASS

8. [HELP]
This command displays information available for

the MultiTasker interface commands.
Command Format: [HELPCn]
Cn = Card ID (n = slot # from 1 to max slots)
Example:
In order to display the RS-232 commands

available for the MT107-103 in slot 8, send the
command [HELPC8]. The commands along with
a brief description will be displayed.

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.

9. [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 [HELPC8] is sent to the card in

slot 8. 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.

10. [?]
This command displays general information

about a MultiTasker and its installed cards.

Example:
The MT107-103 in slot 8 has Input 1 connected

to all outputs. Outputs 1-4 are on, and 5-64 are
off. Send [?C8] to display the feedback status.

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.

12. [AFB]
This command enables/disables the command

acknowledgement feedback, “[ ]”, from the
MT107-103. This setting is automatically saved
to memory and can only be changed by sending
the [AFB] command a second time. Use this
command when sending a large number of
commands to the MT107-103 at the same time.
If monitoring feedback to keep track of events,
the [ACK] command can be used to notify the
system an event has occurred by sending the
[ACK] command last.

Command Format: [AFBmCn]
m = 1 for ON, 0 for OFF
Cn = Card ID (n = # from 1 to max slots)
Example:
Send 16 commands to the MT107-103 in slot 8

to initialize the card with Input 1 to Output 1,
Input 2 to Output 2, and so on. The required
commands are as follows:

[I1O1C8],

[I2O2C8],

etc.

Send the [AFB] command first, and then the
switching commands.

[AFB0C8],
[I1O1C8],
[I2O2C8],

etc.

[I16O16C8]
[ACKC8]

In the above example, the brackets, “[ ]”, will not
be displayed after each command is executed.
However, in order to notify a user or controller
that the last command has been executed, the
[ACK] command is sent last. Since each
command is executed in order, the [ACK]
command is used to display the brackets, “[ ]”,
at the end of the command group.

13. [ACK]
This command displays the open and closed

brackets, “[ ]”, and is intended for use when
feedback is disabled.

Command Format: [ACKCn]
Cn = Card ID (n = # from 1 to max slots)
Example:
See the [AFB] example for details.

14. [STA1]
This command enables automatic feedback

from the front panel. The command affects any
card with auto-feedback capability, not just the
MT107-103. The default at power on or reset is

15. [STA0]
This command disables automatic feedback

from the card and front panel. The command
affects any card with auto-feedback capability,
not just the MT107-103. The default at power-on
or reset is STA0, OFF.

Command Format: [STA0]

16. [...F] – FEEDBACK
After processing a command, an OK or

[ERR001] will be returned as feedback if "F" is
included at the end of a command string.

MATRIX SETUP
The matrix setup commands define the size and

configuration of a matrix. Several matrices can be
defined for a single engine, although only one is
typically used.

17. [MAT]
This command sets the matrix configuration for

the matrix engine. The properties shown in
2-digit format MUST be entered in 2-digit
format.

Command Format:

[MATj;mm;ww;xx;yy;kk;ll;CnS]

j = Matrix ID (j = # from 1 to 9)

mm = Inputs (2-digit # from 01-64)
zz = Outputs (2-digit # from 01-64)
xx = Input offset (2-digit # from 00-99)
yy = Output offset (2-digit # from 00-99
kk = Channel width (2-digit # from 01-32)
ll = Channel spacing (2-digit # from 00-31)
Cn = Engine card slot number

(The left-most slot number of the engine
card is the slot number to use.)

S = Save

Send command with AFB on and without “F”:

[I1O*C8] [ ]

Send command with AFB off and without “F”:

[I1O*C8]

Send command with AFB on and with “F”:

[I1O*C8F] OK

Send command with AFB off and with “F”:

[I1O*C8F] OK

400-0367-005 14

This property saves the configuration to
memory, and allows the configuration to
be recalled any time, even after power-up
or reset.

Adding the “S” to the command will also
make the matrix configuration the default
at power-up. The last configuration ID
created and saved will be the default at
power-up.

In order to change the power-up default
without having to redefine the settings,
see the command [MjCnS].

MULTITASKER

Matrix Configuration Definitions:
Matrix ID: A total of 9 matrix configurations may

be defined in a single engine. Once saved,
the configuration may be recalled by
number without having to redefine the
settings.

Number of Inputs: The number of inputs in the

configuration, or eight times the number of
input cards installed, is the maximum.

If the channel width and spacing are

different, then the number of inputs will be
lower. For example, in a 32X32 matrix with
a width of 4 and a spacing of 7, the number
of inputs would be 8. See Example 1 in this

section for specifics.
Number of Outputs: Same as for Inputs.
Input Offset: The offset defines where Input #1

will be in reference to Input #1 on the Input

Connector Card. Typically, Input #1 would

be Input #1 of the base card. However, an

offset of 8 will make Input #1 start at the

actual Input #9.
Output Offset: Same as for Input Offset.
Channel Width: The number of signals per

channel. The default width is one.
Channel Spacing: The default spacing is zero.

When dealing with multi-cabled signals, the

spacing is typically one less than the

number of inputs on a single card.
Matrix Assembly Layout:
Input cards count from the main Input

Connector Card, right-to-left.
Output cards count from the main Output

Connector Card, left-to-right.

The following table illustrates the card and
channel numbering. The channel numbering is
based upon the default configuration. The
default configuration is configured as a 64X64
Matrix with the following settings:

Number of Inputs = 64
Number of Outputs = 64
Input Offset = 00
Output Offset = 00
Channel Width = 01
Channel Spacing = 00

18. [MjCn]
This command selects the matrix to be active.
Command Format: [MjCn]
j = Matrix ID (j = # from 1 to 9)
Cn = Card ID (n = slot # from 1 to max slots)
Example:
There is a Matrix Engine in slot 8. Send the

command [M1C8] to recall the Matrix 1
configuration of C8.

RECALL MATRIX ON POWER-UP
In order to make Matrix 1’s configuration the

default when power is turned on, send the
[M1C8S]. The feedback will be similar to:

[SAVED]

19. [MODE]
This command sets the matrix switch mode to

blocking or non-blocking. See the following
examples for command functionality.

Command Format: [MODEmCn]

Example: NON-BLOCKING
Send the command [MODE0C8] to turn off

blocking for the engine in slot 8. Next, send the
command [I1O*C8] to connect Input 1 to all
outputs. In non-blocking mode, the inputs will be
switched and the outputs will be enabled.

Example: BLOCKING ON
Send the command [I1O*C8] to connect Input 1

to all outputs. With blocking on, Input 1 will be
connected to all outputs, but only output 1 will
be enabled. The remaining outputs will need to
be enabled using the [ON] command.

Connecting a single output results in the output
being switched and enabled. For example,
sending [I22O22C8] with blocking on results in
Input 22 being connected to Output 22, with
Output 22 being enabled.

MULTITASKER

28. […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 multiple
cards or the same card can be preset.

Example 1:
Switch Input 1 to Output 2, and switch Input 2 to

Output 4 simultaneously with the following
commands:

30. [SEL]
This command selects the path to adjust the

input volume. Send this command first, then use
the [+] and [-] commands to adjust the volume
to the desired level.

CAUTION: This adjustment is on the input,
NOT the output. If Input 1 is connected to more
than one output, adjusting Input 1’s volume will
affect all the outputs connected to Input 1.

Command Format: [SELmmCn]
mm = Input no. (mm = # from 01 to 64)
Cn = Card ID (n = slot # from 1 to max slots)
Example:
There is an MT107-103 in slot 8 that requires

volume adjustment on Input 2. The current
volume level is 10. After sending the following
commands, an optimum level of 15 is obtained:

1. [SEL02C8]

The current volume level is 10.

2. [ - ] [ - ] [ - ]

The level is now 7 and is too quiet.
[I1O2C8P]
[I2O4C8P]
[SW]

29. [SW] – Switch
The Switch command immediately connects

inputs and outputs that were previously set with
the Path command. All cards in the system that
were preset with the Path command will switch
at the same time, not only MT107-103.

See the [PATH] command for examples.

… [O63S0C08] [O64S0C08]

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 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.

36. [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:

400-0367-005 20

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.

MULTITASKER

37. [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.

38. [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.

39. [SID+]
This command sets the card ID of all cards in a

system to their slot number plus an offset value.
Command Format: [SID+n]

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 [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.

40. [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]

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.

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 MT107-103.

41. [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]

42. [RMC]
This command removes one or more cards from

a group.

43. [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 [RMG5].

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

44. [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:

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 of
menu mode sections versus programming
commands.

7.4.2 USING MENU MODE

Do NOT press any keys except those relating to
the current menu. If you press the ENTER key
after entering a letter or digit, the original list of
systems will be displayed.

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 the ENTER
key on the keyboard.

3. The system checks all MultiTaskers on the
RS-232 bus and displays a list of available
systems.

Example: 1: U1

2: U2
3: U3

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

08: MT107-103

6. Enter the 2-digit ID and a menu for the card
will be displayed. In the example above,
enter “08” for the MT107-103.

400-0367-005 24

TROUBLESHOOTING GUIDE 8

We have carefully tested and have found no
problems in the supplied MT107-103. However, we
would like to offer suggestions for the following:

8.1 LED IS NOT LIT Cause 1: The card cage is not plugged in.

Solution: Plug in the card cage. If the LED

lights, the problem is solved. If the
LED is still not on, see Cause 2.

Cause 2: The card is not plugged in all the

way.

Solution: Push the card in all the way. If the

LED is still not on, see Cause 3.

Cause 3: The card cage slot has a problem.

Solution 1: Test the card in other slots. If the

slot was damaged, the card may
work in other slots. If other slots
work and the LED lights, the
problem is the card cage slot and it
may require service. Call ALTINEX
at [phone]. If the other slots
do not work and the LED is still not
lit, see Solution 2.

Solution 2: Take any other known good card

with an LED and verify that the slot
used is good by seeing if the other
card’s LED lights in that slot. If it
lights, then the original card may be
the source of the problem. Call
ALTINEX at [phone].

4. Turn off all outputs.

Starting from the MT107-103 Main Menu, set all
outputs off. Follow the keystrokes below.

3 Select OUT ON/OFF menu
2 Select ALL OUTPUTS OFF

The Main Menu is redisplayed.

8.2 LED IS BLINKING RED Cause 1: The CPU on the card is not

working properly.

Solution 1: Look at the card and verify that

there is no damage. If there is no
damage, see Solution 2.

Solution 2: Verify that all ICs are seated in their

sockets. If the LED is still blinking
red, see Cause 2.

MULTITASKER

Cause 2: The card and its serial device are

not communicating.

Solution: Turn the system off and then back

on again. If there is still an error, call
ALTINEX at [phone].

8.3 NO SOUND 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 sound, see Cause 2.

Cause 2: The card output is not selected.

Solution: Select the card output. See RS-232

accessible commands in Section 7.
If no sound is present, see Cause 3.

Cause 3: Cable connections are incorrect.

Solution: Make sure that the cables are

properly connected and that the
continuity and wiring are good. If
there is still no sound, see Cause 4.
