This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. • Any changes or modifications to the unit not expressly approved by ALTINEX, Inc. could void the user’s authority to operate the equipment. 400-0197-005 2 MULTITASKER™ ABOUT YOUR MT110-101/103 2 TECHNICAL SPECIFICATIONS 3 The MT110-101/103 is a Balanced Audio Matrix Switching Card. This card allows any input to be independently switched to any of the outputs. All inputs and outputs can be wired for unbalanced audio, or balanced audio allowing longer cable runs and superior noise resistance. The MT110-101 is an 8x8 audio matrix with a fixed gain of 0db. The MT110-103 is an 8x8 audio matrix with variable gain for each output. As “transparent” distribution amplifiers, these cards utilize AC coupling on their inputs for ideal signal transfer characteristics. Switching is controlled with easy-to-use ASCII commands from a control system or computer connected to the RS-232 port of a MultiTasker™ enclosure. Each card consumes two slots in a MultiTasker enclosure, and all input and output connections are accomplished via captive screw terminal blocks. Although designated as an 8x8 matrix switcher, the MT110-101/103 can be used in a variety of ways to provide different capabilities. For example, one 8x8 card can handle mono audio while two 8x8 cards handle stereo audio, or a single 8x8 card can be used to create an 4x4 stereo audio matrix. The MT110-101 is a standard matrix switcher, whereas the MT110-103 has individual volume trim control on each output. The HelpInside™ feature allows programmers to have access to command structures and control of the MT110-101/103 from any terminal using the [HELP] command. In conjunction with Altinex’s unique command structure, HelpInside™ provides easier-than-ever control of MultiTasker™ cards with simple keyboard commands. No typing of long keyboard strings is necessary.

Turn off power to the MultiTasker™ enclosure. Step 2. Slide the MT110-101/103 into an available slot in the MultiTasker™ Basic Enclosure in order to connect to the bus. Make sure that the MT110-101/103 card fits into place. Secure the card to the MultiTasker™ by tightening the retainer screws located on the top and bottom of the MT110-101/103 card. Step 3. Connect audio cables from the audio source to the input connector of the MT110-101/103. Connect the output connectors of the MT110-101/103 to the audio equipment through an audio cable. Step 4. Starting from the left, identify the slot number where the MT110-101/103 card is plugged into the Enclosure and note that it is for RS-232 control. Step 5. Turn on power to the MultiTasker™ enclosure. Step 6. 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 Troubleshooting Guide in section 8. OPERATION 7 7.1 RS-232 CONTROL The MT110-101/103 has many advanced remote control capabilities, which are accessible through standard RS-232 communication. Actual control may 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 MT110-101/103, are in a simple ASCII character format. 1. Square brackets “[ ]” are part of the command. 2. Use uppercase letters for all commands. The cards in a MultiTasker™ system are capable of performing various functions, as well as pro...
