MULTITASKER™ ABOUT YOUR MT110-100/102 2 TECHNICAL SPECIFICATIONS MT110-100/102 16-In 8-Out Audio Matrix Switcher Card FEATURES/DESCRIPTION GENERAL Inputs The MT110-100 and MT110-102 are balanced input Audio Matrix Switching Cards. Each card allows any input to be independently switched to any of the outputs. All inputs and outputs can be wired for unbalanced or balanced audio, allowing longer cable runs and superior noise resistance.

MULTITASKER™ INSTALLING YOUR MT110-100/102 7.1.1 RS-232 INTERFACE 6 The RS-232 commands, for the MT110-100/102, are in a simple ASCII character format. Step 1. Turn off power to the MultiTasker™ enclosure. Step 2. Slide the MT110-100/102 into an available slot in the MultiTasker™ Basic Enclosure in order to connect to the bus. Make sure that the MT110-100/102 card fits into place.
MULTITASKER™ 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 to 4 up to 1 to 20 depending on the enclosure. If the value is assigned, the ID may be a maximum of 99. 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) Card ID 0 (C0) is used for the controller and cannot be reassigned.
MULTITASKER™ Example: Example: If Input 1 is connected to all outputs, but only 1 through 4 are on, the feedback after sending the command [C4S], for slot 4, would be similar to the following: A MultiTasker™ with Unit ID #1 has a front panel with part number MT101-105 and contains an MT110-102.
MULTITASKER™ The matrix I/O connections are also read left to right representing outputs 1-8 and the input to which each is connected. The first two digits show the input number to which Output 1 is connected. The third and forth digits are for Output 2 and so on. 7. [STA0] This command disables automatic feedback from the card and front panel. The command affects any card with auto-feedback capability, not just the MT110-102. The default at power on or reset is STA0, OFF.
MULTITASKER™ PATH OPERATION Example: The path for outputs on the same or multiple cards may be preloaded. This 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. Card 5 has Output 1 on. The following commands may be used to turn off the input. Command Format: [ONmCnUiP] GROUP OPERATION m This command disables output ‘m’ for each card in group ‘k’ of unit ‘i’. = Output No.
MULTITASKER™ If ‘F’ is included, use the [OFFmCnPF] command or the [OFFmCnFP] command. In01-Out01 ON In01-Out02 ON In01-Out03 ON etc… FEEDBACK OPERATION After processing a command, an “OK” or “[ERR001]” will be returned as feedback if ‘F’ is included at the end of a command string. P=02 P=OFF P=OFF The notation "P=" at the end of the line indicates the path condition is active. "P=02" on the Output 1 line indicates that after the [SW] command, Input 2 will be connected to Output 1.
MULTITASKER™ Command Format: [ImO*CnUi] Command Format: [OSOmCi] m m = Offset (m = # from 0 to 128) = Input (m = # from 1 to 8) Cn = Card ID (n = slot # from 1 to max slots) Ci = Card ID (i = # from 1 to max slots) Ui = Unit ID (i = # from 0 to 9) Example: Example: [OSO16C8] sets the output offset value to 16 for the card in slot 8. The outputs on card 8 will now be addressed by the value of their physical number plus the offset value. In this case, Output 1 would now be Output 17.
MULTITASKER™ Some cards require more than one slot in the MultiTasker™ system. As an example, some matrix switcher cards require 4 slots. If there are five 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. 21. [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.
MULTITASKER™ Connect the computer to the second unit only and send [SID+20] to set the ID of all the cards in the enclosure to their slot number plus 20. Reconnect both units to the computer. Command Format: [WRCn1Cn2…GkUi] 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.
MULTITASKER™ Example: Upon completion, following: Group 5 consists of the cards located in slots number 2, 4 and 6. Remove all cards from the group by sending the command [RMG5]. The system will return the following feedback: the system will display Command Format: [TESTCn] Cn = Card ID (n = # from 1 to 99) Example: [G5=0] Remove all the members from every group, effectively deleting all groups. Test the internal memory of the MT110-102 in slot 4 by sending the command [TESTC4].
MULTITASKER™ Example: When defined as a volume control key, the key will respond to two conditions: press and release. Below, subroutine 8 starts ramping up when key 8 is pressed. Subroutine 10 starts ramping down when key 10 is pressed. Subroutine 108 stops ramping when either key is released. There is an MT110-102 card in slot 8. Adjust the volume level on Output 2. The current level is set to 10. After sending the following commands, a better level of 15 is obtained: 1.
MULTITASKER™ 35. [RDN] MT110-102 ONLY 37. [RUPm=xx] MT110-102 ONLY This command ramps the output volume down to a level of 00 at a rate defined using the [RAMP] command. This command ramps a specified output’s volume to a user defined level at a rate defined using the [RAMP] command.
MULTITASKER™ 39. [RDNm=xx] MT110-102 ONLY 41. [RAMP] MT110-102 ONLY This command ramps a specified output’s volume down to a user defined level at a rate defined using the [RAMP] command. This command displays the ramping time for 32 steps. The time between each step is equal to the time in seconds divided by 32. Command Format: [RDN=xxCnUi] Command Format: [RAMPCnUi] m Cn = Card ID (n = # from 1 to max slots) = Output No.
MULTITASKER™ 43. [MUT0] MT110-102 ONLY 16 x 8 INPUTS This command turns on the all the outputs without changing the input port selected and without changing any volume settings. 9 10 11 12 13 14 15 16 Command Format: [MUT0CnUi] Cn = Card ID (n = # from 1 to max slots) Ui = Unit ID (i = # from 0 to 9) Example: Send the command [MUT0C4] to enable the outputs for the card in slot 4. 44.
MULTITASKER™ Example: ID Commands In order to display the RS-232 commands available for the MT110-102 card in slot 2, send the command [HELPC2]. The commands along with a brief description will be displayed in the terminal window. 20) [RSI] Reset Card IDs 21) [SIDn] Set all Card IDs 22) [SIDnCi] Set one Card ID 7.3.
MULTITASKER™ TROUBLESHOOTING GUIDE Cause 2: 8 We have carefully tested and have found no problems in the supplied MT110-100/102; however, we would like to offer suggestions for the following: Solution 1: Turn the system off and then on again. If there is still an error, see Cause 3. 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.
MULTITASKER™ 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. ALTINEX POLICY 9.1 LIMITED WARRANTY/RETURN POLICY Please see the Altinex website at www.altinex.com for details on warranty and return policies. 8.4. DISTORTED SOUND Cause 1: The source level is above 1Vp-p Solution: Make sure that the source level is below 1V p-p. If the sound is still distorted, see Cause 2. Cause 2: 9.
