ABOUT YOUR MT109-100 2

MT109-100

8-in 1-out Stereo Audio Switcher Card

The MT109-100 is a Stereo Audio Switcher Card designed for use with the MultiTasker™. When installed in the Basic Enclosure (MT100-100), this card allows the connection of six stereo audio sources to a single receiving device, such as a cassette recorder, mixer, and/or amplifier for sound reinforcement.

Inputs are selected via easy-to-use ASCII commands from a control system or computer connected to the RS-232 port of the MultiTasker™ Basic Enclosure. While the MT109-100 can accept only unbalanced audio inputs, the output can be wired for either balanced or unbalanced audio.

The MT109-100 is primarily designed to utilize the inputs and output offered on the connector panel. However, it also offers a "hidden" feature that enables access to the MultiTasker signal bus. The signal bus spans the width of the MultiTasker Basic Enclosure along the back plane of the unit. Through RS-232 control, the MT109-100 can send or receive stereo audio signals to or from this bus, from any of the applicable cards in the enclosure.

This feature can be used in a variety of ways to expand the capabilities of the card. For example, two MT109-100 cards can be installed in the MultiTasker and the output of one can be routed to an input of the other, creating a 15-input 1-output switcher. Note that the signal bus handles only one stereo audio signal path at a time.

DIAGRAM 3: JUMPER SETTINGS

MULTI-TASKER™

The MT109-100 has 8 external inputs with 1 internal input and 1 output. The internal input is from the Expansion card through a 10-pin ribbon cable, which is connected between P12 of the Expansion card and P12 of the Master card. The 4 external inputs are configured as inputs 1 thru 8.

The 1 internal input is configured as input 7 or input 8. Only one of two internal inputs is used at a time and it depends on how the jumpers on the Expansion are set.

Setting Jumpers:

1) As an Expansion card: set P13 as port 7 (L1E and R1E) or port 8 (L2E and R2E)

2) As a Master card: set jumpers on P23 and P24 as described below. If the Expansion card's jumpers on P13 are set on L1E and R1E, the Master card must select internal

input 7 on P23 (L1E) and P24 (R1E). If the Expansion card's jumpers on P13 are set on L2E and R2E, the Master card must select internal

input 8 on P23 (L2E) and P24 (R2E). Note: The MT109-100 configuration is 8-in, 1-out stereo audio switcher. For a 15-in, 1-out switcher

configuration, use two MT109-100 cards. One as a Master card and the other as an Expansion card. (See page 9.)

INSTALLING YOUR MT109-100 6

Step 1. Determine how the MT109-100 is going

to be configured. The MT109-100 is configured as an 8-in

1-out Stereo Audio Switcher. It may be configured as a system with 15-in, 1-out using two MT109-100 cards. One card is configured as a Master card and the other is configured as an Expansion card.

In Application Diagram, DIAGRAM 4, on page 8, the Master card is set to accept 7 external inputs, 1 internal input and 1 output. The Expansion card has 8 external inputs (inputs 8 thru15). For RS-232 commands, the 8 external inputs of the Expansion card must still be configured as inputs 1 thru 8.

For example, if the master card is at slot 1 and the Expansion card is at slot 2, to select inputs 1 thru 4, use the following commands to select different inputs:

To select input 1: [ON1C1]

2: [ON2C1] 3: [ON3C1] 4: [ON4C1] 5: [ON5C1] 6: [ON6C1] 7: [ON7C1]

To select input 8: [ON8C1] [ON1C2]

9: [ON8C1] [ON2C2] 10: [ON8C1] [ON3C2] 11: [ON8C1] [ON4C2] 12: [ON8C1] [ON5C2] 13: [ON8C1] [ON6C2] 14: [ON8C1] [ON7C2] 15: [ON8C1] [ON8C2]

Step 2. Slide the MT109-100 into an available

slot in the Multi-Tasker™ Basic Enclosure in order to connect to the bus. Make sure that the MT109-100 card fits into place. Secure the card to the Multi-Tasker™ by tightening the retainer screws located on the top and bottom of the card.

Step 3. The LED on the card panel will turn red

indicating that the card is in full operation. A green LED indicates that a signal is present. An LED that is blinking red indicates that the card is experiencing a problem. If the LED is blinking, see Troubleshooting Guide in section 8.

Step 4. Connect audio cables from the audio

source to the input connector of the MT109-100. Connect the output connectors of the MT109-100 to the audio equipment through an audio cable.

Step 5. Starting from the left, identify the slot

number where the MT109-100 card is plugged into the Enclosure and note that it is for RS-232 control.

OPERATION 7

7.1 RS-232 CONTROL

When used in the Multi-Tasker™ Enclosure, the MT109-100 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 MT109-100, 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.

Page 11

MULTI-TASKER™

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 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, 1 to 8, or 1 to 19 depending on the enclosure.

Card ID 0 (C0) is used for the controller. See the MT100-100 User’s Guide for details.

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]

Example: Send the command [VERC2] to check the

version of the MT109-100 in slot 2. The system will return the following feedback:

MT109-100 690-0179-003 MT109-100 = card type

690-0179-003 = software version

2. [C] This command receives the status of the card. Command Format: [CnUi] Cn = card ID (n = # from 1 to max slots)

Ui = unit id (i = 0 to 9) Example: An MT109-100 card is in slot #4. Sending the

command [C4] to the Multi-Tasker™ will yield feedback similar to the following:

If there is no card in slot #4, sending the [C4] command will not return any feedback.

1. [VER] This command displays the software version

and card type for the card. Command Format: [VERCnUi] Cn = Card ID (n = # from 1 to max slots)

Ui = Unit ID (i = # from 0 to 9)

3. [CnS] This command saves the status of the card's

current settings. This configuration will be restored after system is reset or powered off then on.

Cn = card number S = save configuration

Page 12

MULTI-TASKER™

Example: Save the card's current settings by sending the

command [C4S]. The feedback will indicate the card settings were saved and display the saved settings. In the example below, the output volume is set to 20, the active input is 5 and all the input volumes are set to 16.

ON 5 C04 Saved OUTVOL=20/32 INVOL1=16/32 INVOL2=16/32 INVOL3=16/32 INVOL4=16/32 INVOL5=16/32 INVOL6=16/32 INVOL7=16/32 INVOL8=16/32

Example: Card 5 has Input 1 ON and a volume level of

16. Sending the command [OFFC5], turns OFF the output volume, but leaves the volume settings unchanged. When the output volume is turned back on, the original volume level of 16 will be retained.

PATH OPERATION Command Format: [OFFmCnUiP] 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 outputs on multiple cards or the same card may be preloaded.

m = Input number (m = 1 to 8) n = Card ID (n = # from 1 to max slots) i = Unit ID (i = # from 0 to 9) P = Path

FEEDBACK OPERATION Command Format: [OFF…..F] After processing a command, an OK or ER will

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

Example: [OFFC2F]: if path is not set

[OFFC2PF]: if path is set

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

command being sent in memory. When sending the command [VOL1A16C5S], after reset or power up, Input 1 on C5 will be restored with an input volume level of 16.

21. […F] – Feedback After processing a command, an OK or ER will

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

22. […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 outputs on multiple cards or the same card can be preloaded. See examples in ON and OFF commands.

23. [SW] – Switch

Example: There are two MT109-100 cards in slots 6 and

7. Turn OFF the output volume on both cards simultaneously using the commands:

[OFFC6P] [OFFC7P] [SW]

If "F" is included, use the [OFFmCnUiPF] command or the [OFFmCnUiFP] command.

The switch command immediately connects inputs and outputs, which were previously set with the path command on this card and all other cards in the MT100-100.

Example: [ON1C6P]

[ON3C7P] [SW]

The system will return feedback as OK if the unit ID is zero.

27. [CLRG] This command clears the members for a single

group or for all nine groups. The clear command restores the cards to default settings.

Command Format: [CLRGkUi] Gk = Group number (k = # from 1-8)

Ui = Unit ID (i = # from 0-9) Example:

1) To clear group 1, send the [CLRG1U1]

command. This command clears the members for the specified group only.

2) To clear all groups of Unit ID 1, send the

[CLRG[U1] command.

28. [RD] This command displays the members in each

group.

In Multi-Tasker™ 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

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: [WRCn…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)

Command Format: [RDGkUi] Gk = Group number (k = # from 1-8)

Ui = Unit ID (i = # from 0-9) Example: The cards in slots 1, 2 and 19 are part of

group 5 in Unit ID 1. Read the member data for group 5 of Unit ID 1, by sending the command [RDG5U1]. The system will return feedback as follows:

C1C2C19 G5U1 C1 = Card in Slot 1

C2 = Card in Slot 2 C19 = Card in slot 19 G5 = Group 5 U1 = Unit ID 1

29. [CLM] This command removes the members in a

group and leaves the group empty. Command Format: [CLMGkUi] 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:

C1C2C19 G5U1 Now, clear group 5 by sending the command

[CLMG5U1]. Reread the member data as above and note the following feedback:

NONE G5U1

7.4 MENU MODE

MENU MODE commands are RS-232 commands that allow 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 commands. The system then responds based upon selections made by the user.

MENU commands may be issued in response to prompts from within MTSetup™ or other RS-232 communication software.

The MENU driven commands are only available with Multi-Tasker™ Front Panel systems that have the following firmware:

690-0122-015 = Version 015 or later. 690-0123-004 = Version 004 or later. 690-0124-015 = Version 018 or later.

NOTE: In MTSetup™, send the command [VER] from the Terminal Window. The system will respond with feedback similar to the following:

15) [RST] Stop ramping

[690-0122-015 690-0123-004 690-0124-018]

Page 19

MULTI-TASKER™

Check the last three digits against the numbers above to determine if the MENU MODE option 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.

MENU COMMAND Control Switch [ON] Volume [VOL], [RUP], [RDN], [RST] Mute [MUT0], [MUT1], [OFF], [ON] Clear [CLR] Setup Input Volume [VOL] Ramp Time [RAMP] Group [WR], [CLM] Status [VER], [C] Help [HELP] Not Available [?], [CnS], [STA], […S], [...F],

[...P], [SW], [TEST], [CLRG], [RD], and [SEL] with [+], [-]

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 MTSetup™ or other 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 MTSetup™, click the cursor in the Terminal Window and press the ENTER key.

5. The system will interrogate the enclosure and return a list cards installed and their slot locations.

Example: 8 (Slot 8): MT109-100 NOTE: Only cards supporting the MENU

feature will be displayed.

5. Find the alphanumeric character representing the card whose setup requires changing. It will be the first character in the line.

6. Press the number or letter associated with the card, and a menu with options available for that card will appear on the screen. In the example above, press "8".

WARNING: Do NOT enter any characters

except the one relating to the desired menu. Pressing ENTER or RETURN after "8" will force the system back to the original prompt.

7. After selecting the MT109-100 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= ")

TROUBLESHOOTING GUIDE 8

We have carefully tested and have found no problems in the supplied MT109-100; however, we would like to offer suggestions for the following:

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

Solution: Plug card cage in. If the LED lights,

the problem is solved. If the LED 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

LED is still not ON, see Cause 3.

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.

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 (714) 990-2300.

Page 23

MULTI-TASKER™

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 IC’s are seated in their

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

Cause 2: The card and its serial device are

not communicating.

Solution: Turn the system OFF and then ON

again. If there is still an error, see Cause 3.

Cause 3: RS485 communication error

Solution 1: Make sure that the card is pushed

all the way into the slot. If there is still an error, see Solution 2.

Solution 2: Turn the system OFF and then ON

again. If there is still an error, see Solution 3.

Solution 3: Call ALTINEX at (714) 990-2300.

8.3 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.

Cause 3: Cable connections to the

destination are incorrect.

Solution: Make sure that cables are

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

Cause 4: The destination amplifier has a

problem.

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.

8.4 SOUND DISTORTION Cause 1: The source level is above 1V p-p.

Solution: Make sure that the source level is

below 1V p-p. If the sound is still distorted, see Cause 2.

Cause 2: The destination amplifier provides

excessive amplification.

Solution 1: Make sure that the source signal

level is high enough so that the destination amplifier does not have to provide excessive amplification and thereby distort the signal. If there is still sound distortion, see Solution 2.

Solution 2: Call ALTINEX at (714) 990-2300.

Cause 2: The proper card input may not be

selected.

Solution: Select the card input that is used,

by RS-232 accessible commands in section 7. If no sound is present, see Cause 3.

8.5 SOUND LEVEL IS LOW Cause 1 Input volume is low.

Solution 1: Turn up the source volume. If sound

level is still low, see Solution 2.

Solution 2: Turn up the destination amplifier

volume. If the sound level is still low, see Cause 2.
