MULTITASKER

INSTALLING YOUR MT107-103 6

Step 1. Determine the number of slots required for the MT107-103, including the add-on cards. The base MT107-103requires two slots, and a fully loaded 64X64 Matrix Engine requires 16 slots.

Step 2. Turn off power to the MultiTasker system and disconnect from AC power.

Step 3. Carefully, slide the MT107-103into available slots in the MultiTasker enclosure in order to connect to the bus. Make sure that the MT107-103cards fit into place.

Step 4. Secure the cards to the MultiTasker by tightening the retainer screws located on the top and bottom of each card.

Step 5. Connect a cable from an audio source to one of the input connectors on the MT107-103and another cable from an output connector to a receiving device.

Step 6. Starting from the left, identify the slot number where the MT107-103’s Input Connector Card is plugged into the enclosure.

The Input Connector Card is the circuit card on the left-hand side of the engine as it is being installed. Make note of the slot number. It is required for RS-232 control.

Step 7. Restore power to the MultiTasker system. Step 8. The MT107-103is now operational.

OPERATION 7

7.1 RS-232 CONTROL

The MT107-103has 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.

7.1.1 RS-232 INTERFACE

The control commands for the MT107-103are in a simple ASCII character format.

1.Square brackets “[ ]” are part of the command.

2.Use uppercase letters for all commands.

3.Spaces are not legal characters.

The cards in a MultiTasker are capable of performing various functions, as well as providing feedback to the user or control system. Commands instruct a card to perform specific actions or request information from the card. Some commands do both simultaneously.

A command that instructs the card only to perform an action will generate feedback of “[ ]”. The open bracket immediately followed by a closed bracket indicates the card received a valid command. If the command requested information from the card, the feedback generated by the card is the acknowledgement of having received a valid command. Invalid commands generate feedback that includes “ERR” plus an error code.

Example: [ERR001]

After processing a command, an “OK” or error 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.
