MULTI-TASKER

INSTALLING YOUR MT104-102 6

Step 1. Slide the MT104-102into an available slot in the Multi-Tasker™ Enclosure in order to connect to the bus. Make sure that the MT104-102card fits into place. Secure the card to the Multi-Tasker™ by tightening the retainer screws located on the top and bottom of the MT104-102card.

Step 2. The LED on the card panel will turn red indicating that the card is in full operation. A green LED indicates that a signal is present. 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.

Step 3. Connect a coaxial cable from the video source to the input connector of the

MT104-102. Connect the output connectors of the MT104-102to the display devices through a coaxial cable.

Step 4. Starting from the left, identify the slot number where the MT104-102card is plugged into the Enclosure and note that it is for RS-232 control.

OPERATION 7

7.1 RS-232 CONTROL

When used in the Multi-Tasker™ Enclosure, the MT104-102has 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 MT104-102are 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 or if the unit ID is zero.

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 (power off

&power on again).

7.2DESCRIPTION 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.

Card ID is an assigned value from 1 to 19 (1 to 8 or 1 to 2 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 on software definitions or a third party control system.

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 MT104-102card.

Command Format: [VERCnUi]

Cn = card ID number (n = # from 1 to 19) (1-8 for MT100-101 or 1-4 for MT100-106)

Ui = Unit ID (i = # from 0 to 9) (refer to the MT100- 100 user’s guide for explanation)
