Installing Your MT115-111, Operation, RS-232 Control

MULTITASKER

INSTALLING YOUR MT115-111

Step 1. Determine the appropriate switch settings using DIAGRAM 3 on page 8.

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

Step 3. Remove an unused slot cover (MT200-101). Identify the slot number and note that it is for RS-232 control.

Step 4. Slide the MT115-111into the enclosure in order to connect it to the bus. Make sure that the card fits into place and secure the card by tightening its retainer screws.

Step 5. Restore power to the MultiTasker enclosure. The LEDs for each input should be on and red.

Step 6. Connect the computer/component video and audio devices to Outputs 1 and 2.

Step 7. Connect the 4TP IN1 to the output of its Twisted Pair transmitter. If a properly formatted input signal is available, the input LED will turn green.

Step 8. Connect the 4TP IN2 to the output of its Twisted Pair transmitter. If a properly formatted input signal is available, the input LED will turn green.

Step 9. The MT115-111is ready for operation.

Step 10. Video equalization is provided to fine-tune the displayed image on the remote display. The equalization adjustments on the MT115-111and Twisted Pair

transmitter work together. Adjust equalization by setting both the transmitter and receiver to minimum. Then slowly increase the equalization on the receiver until an image is present. Then adjust the equalization on both units for the best image.

Step 11. The MT115-111also has video gain adjustment capability through RS-232 control. See the following section for RS-232 command details.

OPERATION

7.1 RS-232 CONTROL

The MT115-111has 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 MT115-111, are 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 1:	[ERR001]	Error number
Example 2:	[ERRC04]	Card error C4

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.
