MULTITASKER ABOUT YOUR MT110-103 2 TECHNICAL SPECIFICATIONS MT110-103 8X8 Mono Audio Matrix Switcher Specifications are subject to change. See www.altinex.com for up-to-date information. The MT110-103 is a Balanced Audio Matrix Switching Card. This card allows any input to be independently switched to any or all of the outputs. All inputs and outputs can be wired for unbalanced audio, or they can be wired for balanced audio allowing longer cable runs and superior noise resistance.

MULTITASKER INSTALLING YOUR MT110-103 Step 1. Turn off power enclosure. to the 6 OPERATION MultiTasker 7.1 RS-232 CONTROL The MT110-103 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. Step 2. Slide the MT110-103 into an available slot in the MultiTasker enclosure in order to connect to the bus. Make sure that the MT110-103 card fits into place.
MULTITASKER 7.2 DESCRIPTION OF COMMANDS Each command consists of three Function, Card ID, and Unit ID. [ Function , Card ID , Unit ID ] COMMAND ORGANIZATION parts: The RS-232 commands in this section are organized into the following 5 categories: Basic Commands Feedback Control Card Control Volume Ramping Controls Card IDs Groups Example: [VERC3U2] VER C3 U2 = Function = Card ID or Group ID = Unit ID (optional for Unit ID 0) For Function, see a detailed explanation under each command description.
MULTITASKER 2. [C] Example: This command receives the status of the card.
MULTITASKER 6. [TEST] Example: This command performs a series of tests on the internal memory of the card. 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 [FBD1] to slow down the rate at which the card sends feedback to the system. Command Format: [TESTCn] Cn = Card ID (n = # from 1 to 99) Example: 9. [?] Test the internal memory of the MT110-103 in slot 4 by sending [TESTC4].
MULTITASKER 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. MT110-103 = Card model number VR690-0152-011 = Firmware version ON1111111 = Output ON/OFF status MA01010101...01 = Matrix connections MX8x8C04 = Matrix configuration VO323232...
MULTITASKER 4x4 CARD CONTROL INPUTS 1a 1b 2a 2b 3a 3b 4a 4b Card control commands allow the main functions of the card to be executed over the RS-232 bus, or from the front panel’s programmable keys. 14. [MATmXy] The matrix command allows the matrix switcher to be setup for different matrix sizes. The following tables show how the inputs and outputs will be configured when the matrix is changed. The input and output layouts are as viewed from the front of the card.
MULTITASKER GROUP OPERATION Example: This command enables one or all outputs for all cards in a group. C4 has Output 1 turned on. The following commands may be used to turn off the input. Command Format: [ONmGk] 1) [OFF1C4]: Turn off only Output 1. m 2) [OFFC4]: Turn off all outputs. = Output number (m = # from 1-8) Gk = Group number (k = # from 1-8) GROUP OPERATION Example: This command disables one or all outputs for all cards in a group.
MULTITASKER 17. [IO] 21. [OSI] This command connects a single input to a single output in the current matrix configuration. This command sets the input offset value that is applied to all inputs. The default is zero, or Input 1 equals Input 1.
MULTITASKER 24. [SEL] 27. [MUT0] This command is the output select command. It sets the path to adjust the output volume level for the current matrix. It is used in conjunction with the [ + ] and [ - ] commands. This command turns on the all the outputs without changing other settings. Command Format: [MUT0Cn] Cn = Card ID (n = # from 1 to max slots) Command Format: [SELmCn] m Example: = Output No. (m = # from 1 to 8) Send the command [MUT0C4] to enable the outputs for C4.
MULTITASKER {WRS8=RUPC4} //Ramp Up {WRK8=8,108,0,0,0} //Press= start, release= stop {WRS10=RDNC4} //Ramp Down 31. [RUPm] {WRS108=RSTC4} //STOP RAMPING This command ramps up the volume for the specified output. The ramping continues to its maximum level at the rate defined using the [RAMP] command. The ramping may be stopped at any time using the [RST] command.
MULTITASKER 35. [RST] Command Format: [RDNmCn] Cn = Card ID (n = # from 1 to max slots) Ramp the volume for Output 8 from a starting level of 32 down to 00 for C4. Send the command [RDN8C4] and the system will respond with the following feedback: This command stops ramping and maintains the last volume setting. It can be used as a stand-alone command, or as a volume key on the front panel. As a volume key, the ramping action begins when the key is depressed and then stops when the key is released.
MULTITASKER 37. [RAMP=x] ID COMMANDS This command sets the ramp rate for 32 steps. The range is from 4s to 18s, in 2s steps. 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.
MULTITASKER 39. [SIDn] Example: 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. 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.
MULTITASKER 45. [RMG] 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 MT110-103. This command deletes one or all groups. 43. [WR] Remove all cards from G52 by sending [RMG5]. The system will return the following feedback: Command Format: [RMGk] Gk = Group ID (k = # from 1-8, * for all) Example: This command adds cards to a group.
MULTITASKER 7.3.
MULTITASKER 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. 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: 7.4.
MULTITASKER 7.4.4 MT110-103 MENUS 1. Switch Input 2 to Output 1 Following are the menu items available on the MT110-103’s Main Menu. The expanded menu contains values that indicate the current setting or value of a parameter. The value is usually in parentheses, or otherwise indicated at the top of a sub-menu. In some cases, additional comments are provided for clarification and are not part of the menu feedback. Follow the keystrokes below to connect Input 2 to Output 1.
MULTITASKER 8 Cause 2: We have carefully tested and have found no problems in the supplied MT110-103; however, we would like to offer suggestions for the following: The proper input card 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. TROUBLESHOOTING GUIDE 8.1 LED IS NOT LIT Cause 1: Card cage is not plugged in. Cause 3: Solution: Plug card cage in. If the LED lights, the problem is solved.
MULTITASKER 8.5. SOUND LEVEL IS LOW Cause 1: ALTINEX POLICIES Volume levels are inappropriate. 9.1 LIMITED WARRANTY/RETURN POLICIES Solution 1: Turn up the source volume. If sound level is still low, see Solution 2. Please see the ALTINEX website at www.altinex.com for details on warranty and return policies. Solution 2: Turn up the destination amplifier volume. If the sound level is still low, see Cause 2. Cause 2 Poor signal transmission.
