These cards are ideal for distributing audio to
recording devices in dubbing racks using simple
off-the-shelf cables. As an example, the MT108104/(105) can distribute audio to four cassette
recorders or it can handle the audio portion of A/V
distribution to four VCRs.
As a “transparent” line driver, these cards utilize
AC coupling on their inputs for ideal signal transfer
characteristics. The power indicator on the card is
a red LED indicating the board has power applied.
These cards consume one slot each.

INSTALLING YOUR MT108-104/(105)
6
Step 1. Slide the MT108-104/(105) into an
available slot in the Multi-Tasker™ Basic
Enclosure in order to connect to the bus.
Make sure that the MT108-104/(105) card
fits into place. Secure the card to the
Multi-Tasker™ by tightening the retainer
screws located on the top and bottom of
the MT108-104/(105) card.
Square brackets “[
command.
]” are part of the
2.
Use uppercase letters for all commands.
7.2 DESCRIPTION OF COMMANDS
Each command consists of three parts:
function, card ID, and unit ID. [Function, Card
ID, Unit ID].
Example:
Step 2. The LED on the card panel will turn red
indicating that the card is in full operation.
An LED that is blinking red indicates that
the card is experiencing a problem. If the
LED is blinking, see the Troubleshooting
Guide in section 8.
[VERC3U2]
VER = function
C3 = Card ID
U2 = Unit ID
For detailed information regarding function, see
each command description.
Step 3. Connect an audio cable from the audio
source to an available input connector (4
inputs) of the MT108-104/(105). Connect
any or all of the four available outputs of
the MT108-104/(105) to audio equipment.
Card ID is an assigned value from 1 to 19, (1 to
8 or 1 to 4 depending on which enclosure is
being used); based on which slot the card is in.
Card ID 0 (C0) is used for the controller (see
user’s guide for the MT100-100). Changing the
position of a card will significantly affect the
commands recorded on software definitions or
a third party control system.
Step 4. Starting from the left, identify the slot
number where the MT108-104/(105) card
is plugged into the Enclosure and note
that it is for RS-232 control.
OPERATION
1.
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 0, then each command can be used
without Ui (use command [SETU0]; see user’s
guide for the MT100-100).

7.1 RS-232 CONTROL
The outputs of the MT108-104 card are always
enabled; therefore, no RS-232 control is
necessary.
Example:
[VERC3]: for unit ID zero
[VERC3Ui]: for unit ID other than zero
[VERC3]: equivalent to [VERC3U0]
When used in the Multi-Tasker™ Basic
Enclosure, the MT108-105 has many advanced
remote
control
capabilities,
which
are
accessible through a standard RS-232
communication. The actual control may be
accomplished using a computer control system
or any other device capable of sending RS-232
commands.
1. [VER]
This command displays the software version
and card type of the MT108-105 card.
Command Format: VERCnUi

Card Status Saved
2. [C]
4. [ + ] or [ - ]
This command receives the status of the card.
This command increases or decreases volume.
It immediately follows the [SEL] command. Any
command other than [ + ] or [ - ] will reset the
previous selection and the [SEL] command will
need to be reissued.
Command Format: [CnUi]
Cn = card ID (n = from 1 to 19)
(1-8 for MT100-101 or 1-4 for MT100-106)
Ui = unit ID (i = from 0 to 9) (refer to the
MT100-100 user’s guide for explanation)
Example:
Example:
If the status of audio card 2 of unit zero is as
follows:
If one MT108-105 card is plugged in slot #2 of
unit 3, sending the [C2U3] command, the
Multi-Tasker™ Basic Enclosure will return
feedback as:
Vol1=16/16
Vol2=0/16
Vol3=0/16
Vol4=0/16
Vol1=16/16
Vol2=12/16
Vol3=8/16
Vol4=4/16
Send the commands:
[SEL1C2] [ - ] [ - ]
[SEL2C2] [ + ] [ + ]
[C2]
There are 16 levels for amplitude. In the above
example, Input 1 (Vol1) is at level 16 out of 16
or maximum amplitude. Input 2 is at 12 or ¾
amplitude. Input 3 is at ½ volume and Input 4 is
at ¼ volume.
The new status will be as follows:
Vol1=14/16
Vol2=2/16
Vol3=0/16
Vol4=0/16
If there is no card plugged into slot #2 of unit 3,
the Multi-Tasker™ Basic Enclosure will not
return any feedback.
Note: The [SEL], [ + ], and [ - ] commands can
also be used to control the volume for a group
of cards.
3. [CiS]
Command Format: [SELmGkUi]
This command saves the current status of the
card's output volume configuration. This
configuration will be restored after system is
reset or powered off then on.

[WAIT] time after sending this command.
Example:
If cards 1, 2, and 3 are grouped as group 5 of
unit 1, send the command [SEL1G5U1]. Then
send the commands [ + ], and [ - ] to increase
or decrease the volume for cards 1, 2, and 3
simultaneously.
[CLRCnUi]
Cn = card ID No. (n = slot # from 1 to 19)
(1-8 for MT100-101 or 1-4 for MT100-106)
Ui = Unit ID number (i = 0 to 9)
5. [SEL]
After [CLR] is executed, send [Cn] and receive
feedback as:
This command selects the individual input for
adjusting the volume level of each output.
Vol1=16/16
Vol2=16/16
Vol3=16/16
Vol4=16/16
Command Format: [SELmCnUi]
SELm = volume select for output m. (m = 1-4)
Cn = card ID (n = from 1 to 19)
(1-8 for MT100-101 or 1-4 for MT100-106)
8. […S] – Save
Ui = unit ID (i = from 0 to 9)
This command will save the volume
configuration command being sent in memory.
When sending the command [VOL1A10C4S],
after reset or power up, the volume level of
output 1 on C4 will be level 10.
After the [SEL] command is executed, the [ + ]
and [ - ] commands must be executed
immediately in order to increase or decrease
the volume. Any other command (or an empty
command such as [ ] ) will terminate the [SEL]
command.
9. [CLR] - Group
This command clears the members for all nine
groups.
6. [VOL]
This command allows the Multi-Tasker to send
an absolute volume level to the MT108-105.
[CLRGkUi]
Gk = group number (k = # from 1-9)
Command Format: [VOLmAnCi]
Ui = unit number (i = # from 0-9)
VOLm = output select (m = 1 to 4)
Example:
An = amplitude level (n = 0 to 16)
a)
To clear group #1, send the command
[CLRG1U1]. This command clears the
members for the specified group only.
b)
To clear all groups of unit 1, send the
command [CLR G[U1].
Ci = card ID (i = from 1 to 19)
(1-8 for MT100-101 or 1-4 for MT100-106)
Ui = unit ID (i = from 0 to 9)
Example:
10. [WR]

TROUBLESHOOTING GUIDE
Example:
We have carefully tested and have found no
problems in the supplied MT108-104/(105);
however, we would like to offer suggestions for the
following:
To group cards #1, 2, and 3 as group 5 of unit
#1, send the command [WRC1C2C3G5U1].
After executing this command, cards 1, 2, and 3
of unit 1 will be grouped together as group 5.

• 8.2 NO SOUND
11. [RD]
• 8.3 SOUND DISTORTION
• 8.4 SOUND LEVEL IS LOW
This command displays the members in each
group.
8.1 LED IS NOT LIT
Command Format: [RDGkUi]
Cause 1: Card cage is not plugged in.
Gk = group number (k = # from 1-9)
Solution:
Ui = unit number (i = # from 0-9)
member = C1 - C19 (card 1 to 19)
Plug card cage in. If the LED lights,
the problem is solved. If the LED is
still not lit, see Cause 2.
Example:
Cause 2: Card is not plugged in all the way.
To read member data for group 1 of unit 1,
send the [RD] command. The system will return
feedback as C1C2C3 G5U1.
Solution:
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 may work in other slots. If
other slots work and the LED lights,
the problem is the card cage slot.
The card cage may require service.
Call ALTINEX at (714) 990-2300. If
the other slots do not work and the
LED is still not lit, see Solution 2.
