Installing Your MULTI-TASKER, Operation

MULTI-TASKER

INSTALLING YOUR MULTI-TASKER™

Step 1. Slide the MT104-107into an available slot in the Multi-Tasker™ Enclosure in order to connect to the bus. Make sure that the MT104-107card fits into place. Secure the card to the Multi-Tasker™ by tightening the retainer screws located on the top and bottom of the MT104-107card.

Step 2. The LED on the card panel will turn red indicating that the card is in full operation.

Step 3. Connect a coaxial cable from the video source to the input connector of the MT104-107. Connect the output connectors of the MT104-107to the display devices through a coaxial cable.

Step 4. Starting from the left, identify the slot number where the MT104-107card is plugged into the Enclosure and note that it is for RS-232 control.

OPERATION

7.1 RS-232 CONTROL

When used in the Multi-Tasker™ Enclosure, the MT104-107has 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 MT104-107are 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 such as [ON], [OFF], and [ IO] that end 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.

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 from 1 to 19 (1 to 8 or 1 to 4 depending on which enclosure is being used), which represents the number of slots. Card ID 0 (C0) is used for the controller (see user’s guide for the MT100 -100). Changing the position of a card will significantly affect the commands recorded in software definitions or a third party control system.

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 0, then each command can be used without Ui (use command [SETU0]; see user’s guide for the MT100 -100).

Example:
[VERC3]:	for unit ID zero
[VERC3Ui]:	for unit ID other than zero
[VERC3]:	equivalent to [VERC3U0]

1.[VER]

This command receives the software version and card type for the MT104-107card.

Command Format: [VERCnUi]

Cn = card ID (n = # from 1 to max slots) Ui = Unit ID (i = # from 0 to 9)

Example:

An MT104-107card is in slot #2 of unit 3. Retrieve the card type and version by sending
