INSTALLING YOUR MT106-103 6

Step 1. Turn off power to the MultiTasker system and disconnect from AC power.

Step 2. Remove a slot cover (MT200-101) from one of the unused slots. Identify the slot number and note that it is for RS-232 control.

Step 3. Slide the MT106-103into the MultiTasker enclosure in order to connect it to the bus. Make sure that the card fits into place and then secure the card by tightening its retainer screws.

Step 4. Make one or more of the following input video connections:

§Connect a BNC-type cable from the video source (camera, VCR, etc.) to the Video input connector.

§Connect an S-Video cable from the S-Video source (DVD, laptop, etc.) to the S-Video input connector.

§Use one of the two RCA to 15-pin HD cables included with the MT106-103to connect the component video source (DVD, satellite, media player, etc.) to the component video input connector.

§Connect the RGBHV video output of a computer to the PC Bypass input.

Step 5. Connect the output connector of the MT106-103to the display device through

aVGA-type (15-pin HD) cable. If the output of the MT106-103will be component video, use the second RCA to 15-pin HD cable included with the MT106-103to connect the output of the Scaler to the input of the display.

Step 6. Restore power to the MultiTasker system.

Step 7. The default input is the Video input port. Use AVSnap® or other communication software to change the MT106-103input. See the [IN] command in section 7.2 or section 7.4 for Menu Mode to change the selection.

OPERATION 7

7.1 RS-232 CONTROL

The MT106-103has many advanced remote-control capabilities accessible through standard RS-232 communication. Control may be accomplished through a computer control system or any other device capable of sending RS-232 communication.

7.1.1 RS-232 INTERFACE

The control commands for the MT106-103are 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 system 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 about the status of 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 of “[ERR001]”.

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.

7.2 DESCRIPTION OF COMMANDS

Each command consists of three parts: Function, Card ID, and Unit ID.
