Step 1. Turn off power to the MultiTasker
enclosure.
Step 2. Slide the MT113-100/101 into an available
slot in the MultiTasker Enclosure in order to connect to the bus. Make sure that the
MT113-100/101 card fits into place.
Step 3. Secure the card to the MultiTasker by
tightening the retainer screws located on the top and bottom of the MT113-100/101 card.
Step 4. Turn on power to the MultiTasker. Step 5. The fan on the card will turn on. Step 6. Connect audio cables from the audio
source to the input connector of the MT113-100/101. Connect the output connectors of the MT113-100/101 to the audio equipment through an audio cable.
Step 7. Starting from the left, identify the slot
number where the MT113-100/101 card is plugged into the enclosure and note that it is for RS-232 control.
OPERATION 7
7.1 RS-232 CONTROL
The MT113-100/101 has many advanced remote control capabilities, which are accessible through standard RS-232 communication. The actual controlling can be accomplished through a computer control system or any other device capable of sending RS-232 commands.
7.1.1 RS-232 INTERFACE
The RS-232 commands, for the MT113-100/101 are in a simple ASCII character format.
1. Square brackets “[ ]” are part of the command.
2. Use uppercase letters for all commands.
After processing a command, an OK or ER 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.
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
For Function, see a detailed explanation under each command description.
The Card ID is an assigned value. It is equal to the enclosure slot number in which the card is installed. The value can range from 1 to 4 up to 1 to 20 depending on the enclosure.
Card ID 0 (C0) is used for the controller. See the MT100-100 User’s Guide for details.
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.
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]

16 down to 1 for the card in slot #8. Send the command [RDNC8] and the system will respond with the following feedback:
[16][15][14]…[01]
26. [RDN=] This command ramps the OUTPUT volume
down to a user defined level at a rate defined using the [RAMP] command.
Command Format: [RDN=xxCnUi] xx = Stop Level (xx = # from 01-16) Cn = Card ID (n = # from 1 to max slots) Ui = Unit ID (i = # from 0 to 9) Example: Ramp the output volume from a starting level of
16 down to 8 for the card in slot #8. Send the command [RDN=8C8] and the system will respond with the following feedback:
[16][15][14]…[8]
27. [RST] This command stops ramping and maintains the
last volume setting. Command Format: [RSTCnUi] Cn = Card ID (n = # from 1 to max slots) Ui = Unit ID (i = # from 0 to 9) Example: The card in slot #8 is ramping from 1 to 16.
Send the command [RSTC8] and the card will stop ramping the volume. The last displayed volume setting is the new volume level.
28. [RAMP] This command displays the ramping time for 16
steps. The time between each step is equal to the time in seconds divided by 16.
Command Format: [RAMPCnUi] Cn = Card ID (n = # from 1 to max slots) Ui = Unit ID (i = # from 0 to 9) Example: Display the ramp rate setting for the card in slot
#8 by sending [RAMPC8]. The system will respond with feedback similar to the following:
RAMPTIME = 6 SECONDS
29. [RAMP=] This command sets the ramp rate for 16 steps.
The settings range from 4 to 18 seconds, in two-second intervals.
Command Format: [RAMP=xCnUi] x = Rate in Seconds
4 = 0.25 seconds/step 6 = 0.38 seconds /step 8 = 0.50 seconds /step 10 = 0.63 seconds /step 12 = 0.75 seconds /step 14 = 0.88 seconds /step 16 = 1.00 seconds /step
18 = 1.13 seconds /step Cn = Card ID (n = # from 1 to max slots) Ui = Unit ID (i = # from 0 to 9)

MULTITASKER™
Example: There is an MT113-100/101 in slot #5. Send the
command [RAMP=16C5] to set the ramp rate to 16 seconds. After this is set, any ramping will occur at a rate of 16 steps in 16 seconds, or 1 second per step. Confirm the setting by sending the command [RAMPC5] and receiving the feedback:
RAMPTIME = 16 SECONDS
30. [TEST] This command performs a test on the internal
memory. Upon completion, the system will display the results. If there are no problems, the system will display the following:
MEMORY IS GOOD Otherwise, failures will be indicated. Command Format: [TESTCnUi] Cn = Card ID (n = slot # from 1 to max slots) Ui = Unit ID (i = # from 0 to 9) Example: There is an MT113-100/101 in slot #10. In order
to test the internal memory, send the command [TESTC10].
31. [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: [FBDmCnUi] m = Delay (0= no delay, 1= delay 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 displayed on the screen, but most is missing. Send the command [FBD1C4] to slow down the rate at which the card sends feedback to the system.
CARD 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.
The ID commands work with all MultiTasker Front Panel systems. However, front panels that have firmware releases prior to the following will not be able to address Card ID's 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. NOTE: In MTSetup, send the command [VER]
from the Terminal Window. The system will respond with feedback similar to the following:
[690-0122-015 690-0123-005 690-0124-019]
Check the last three digits against the numbers above to determine if the Card ID commands can address all 99 Card ID's.
Some cards require more than one slot in the MultiTasker system. As an example, some matrix switcher cards require 4 slots. If there are 5 of these cards installed, they would be numbered C4, C8, C12, C16 and C20. Changing the Card 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.

32. [RSI] This command resets the card ID's in the
system. After sending this command, each card ID in the system will match the slot number of the card. Use this command along with the SID commands that follow. The [RSI] command MUST be used prior to changing Card ID's once they have already been set.
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.
33. [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.
34. [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.
35. [SID+] This command sets the ID of all the cards in a
system to their slot number plus an 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 Card ID defaults which are equal to their slot numbers. The second unit will have the same Unit ID, but will have the card ID's offset by 20.
Connect the computer to the second unit only. Send the command [SID+20] to set the ID of all cards in the enclosure to their slot number plus
20. Reconnect both units to the computer. The cards in the first unit will be referenced as
Card ID's 1-20 and the cards in the second unit will be referenced by Card ID's 21-40.
36. [RSN] This command reads the slot number of the
card with a specified ID number, and returns the value to the system to be displayed in the terminal window. 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™
37. [HELP] This command displays 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 display the RS-232 commands
available for the MT113-100/101 card in slot #2, send the command [HELPC2]. The commands along with a brief description will be displayed in the Terminal Window.
38. [WR] This command groups multiple cards in the
enclosure allowing all the group members to be controlled simultaneously with the same command. Each unit may define a maximum of eight groups.
In MultiTasker systems with audio and video cards, boards are typically grouped as follows:
Group 1 = Video Cards Group 2 = Audio Cards Group 3 = Video and Audio Cards
Now, when a command is sent to G1, each board in G1 will execute the same command.
39. [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…GkUi] Cn = Card ID (n= # from 1 to max slots) Gk = Group number (k = # from 1-8) Ui = Unit ID (i = # from 0-9) Example: Group 1 consists of the cards located in slots
numbered 1, 2, 3, 4 and 5. Remove just cards #4 and #5 from the group by sending the command [RMC4C5G1]. The system will return the following feedback:
G1=C1C2C3
40. [RMG] This command may be used to delete an entire
group, or all groups. REMOVE ONE GROUP MEMBERS
If assigning group commands to button functions, it is best to use the "Press and Hold on Power Up" to make group settings.
Command Format: [WRCn1Cn2…GkUi] Cn = Card ID (n = slot # from 1 to max slots) Gk = Group number (k = # from 1-8) Ui = Unit ID (i = # from 0-9) Example: To group cards 1, 2, and 3 as group 5 of
Unit ID 1, send the command [WRC1C2C3G5U1]. After executing this command, cards 1, 2 and 3 will be grouped together as group 5 of Unit ID 1. The system will return the following feedback:
G1=C1C2C3
Remove all the members from the group, effectively deleting the group.
Command Format: [RMGkUi] Gk = Group number (k = # from 1-8) Ui = Unit ID (i = # from 0-9) Example: Group 1 consists of the cards located in slots
number 1, 2 and 3. Remove all cards from the group by sending the command [RMG1]. The system will return the following feedback:
G1=EMPTY
18

MULTITASKER™
REMOVE ALL GROUPS Remove all the members from every group,
effectively deleting all groups. Command Format: [RMG*Ui] Ui = Unit ID (i = # from 0-9) Example: Group 1 consists of cards 1 and 2. Group 2
consists of cards 1, 2, 3, 4 and 5. Delete all the groups by sending the command [RMG*]. The system will return the following feedback:
G1-G8:EMPTY
41. [RD] This command reads and then displays the
members in each group. Command Format: [RDGkUi] Gk = Group number (k = # from 1-8) Ui = Unit ID (i = # from 0-9)
Example: Group 5 of Unit ID 1 contains the cards in slots
1, 2 and 19. Read the member data for group 5 of Unit ID 1. Send the command [RDG5U1] and receive the following feedback:
G1=C1C2C19 Now, clear group 5 by sending the command
[CLMG5U1]. Reread the member data as above and note the following feedback:
G1=EMPTY

7.4 MENU MODE
MENU MODE commands are RS-232 commands that allow virtually the same functionality 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 system then responds based upon selections made by the user.
The MENU driven commands are only available with MultiTasker Front Panel systems 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 system will respond with feedback that is 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 the MENU MODE option 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 displayed in the menu mode, but 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. Insert the card into an empty slot and push
in all the way for a secure fit.
3. Reset the system or power the system off
and then on.
4. In the terminal window, press ENTER.
5. The system will interrogate the enclosure
and return a list of cards installed and their
slot locations. Example: 08: MT113-100 NOTE: Only cards supporting the menu
feature will be displayed.
5. Find the two digit number representing the card ID whose setup requires changing. They will be the first two characters in the line.
6. Enter the two digit number associated with the card, and a menu with options available for that card will appear on the screen. In the example above, press "08".
WARNING: Do NOT enter any characters
except those relating to the desired menu. Pressing ENTER after "08" will force the system back to the original prompt.
7. After selecting the MT113-100 as described above, the system will prompt for selections specific to that card.
8. 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 main functions related to the card. Press the key representing the menu item for access. A sub menu will appear next.
2. SUB MENUS Each sub menu will display either another
menu (sub menu) or a list of available options or settings. Press the key corresponding to the menu choice to change a setting or select the next menu.
NOTE: Pressing the ESCAPE (ESC) key in
most menus will take you up to the previous menu without making changes in the current menu.

TROUBLESHOOTING GUIDE 8
We have carefully tested and have found no problems in the supplied MT113-100/101; however, we would like to offer suggestions for the following:
8.1 FAN DOES NOT SPIN Cause 1: Card cage is not plugged into
power outlet.
Solution: Plug card cage in. If the fan turns
on, the problem is solved. If the fan is still not on, see Cause 2.
Cause 2: Card is not plugged in all the way.
Solution: Push the card in all the way. If the
fan still does not spin, see Cause 3.
Cause 3: 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 fan is on, the problem is the card cage slot. The card cage may require service. Call ALTINEX at (714) 990-2300. If other slots do not work, see Solution 2.
Solution 2: Take any other known good card
with an LED or fan and verify that the slot used is good by seeing if the other card’s LED (or fan) turns on. If so, then the original card may be the source of the problem. Call ALTINEX at (714) 990-2300.
8.2 NO SOUND Cause 1: The source has a problem.
Solution Check the source and make sure
that it is working at an appropriate volume level and all source connections are correct. If the source is working and there is still no sound, see Cause 2.
3 Displays card status NOTE: The status will be displayed, followed
by the Main Menu being redisplayed.

MULTITASKER™
Cause 2: The card settings are wrong.
Solution: Verify the card volume settings are
at maximum and that mute is off. (See section 7). If no sound is present, see Cause 3.
Cause 3: Cable connections are incorrect.
Solution: Make sure the cables are connected
properly and that the continuity and wiring are good. If there is still no sound present, see Cause 4.
Cause 4: The destination amplifier is bad.
Solution 1: Make sure that the destination
amplifier is powered. If there is still no sound, see Solution 2
Solution 2: Set the volume of the destination
amplifier to a reasonable level. If there is still no sound, call ALTINEX at (714) 990-2300.
