MULTITASKER

LED COMMANDS

LED commands apply to the MT101-115/117only and are used to control the LED states and retrieve matrix settings based upon key entries. The LED states (on, off, flashing) may be controlled directly over the RS-232 bus or through the use of subroutines programmed into the front panel.

30.{LEDn=}

This command activates a single key’s LED or all LEDs.

Command Format: {LEDn=s}

n = # from 1 to 36 for a single LED

=* for all LEDs s = # from 0 to 2

=0 for OFF

=1 for ON

=2 for FLASH Examples:

Command	LED#	Results

{ LED36=2 }	36	FLASH

{ LED10=1 }	10	ON

{ LED*=0 }	ALL	OFF

{ LED*=1 }	ALL	ON

{ LED*=2 }	ALL	FLASH

31. {LEDm-n}

This command activates the LEDs for a sequential range of keys.

Command Format: {LEDm-n=s}

m,n = # - ## for a sequential range from 1 to 36

=* for all LEDs s = # from 0 to 2

=0 for OFF

=1 for ON

=2 for FLASH

Examples:

Command	LED#	Results

{ LED1-10=1 }	1 to 10	ON

{ LED13-36=0 }	13 to 36	OFF

32.{CLFC}

This command is a debug tool that clears the memory of input-to-output connections used to flash the LEDs for a single matrix card. This command is used in conjunction with the {STA} command.

Command Format: {CLFCn}

Cn = card number (n is # from 1 to max slots)

Example:

Key 2 on the front panel is programmed with the {STA} command. See the {STA} command for details.

A user connects Input 1 to Outputs 1, 2, and 3 on C2 from the front panel. The connection is verified by pressing Key 2 and then the Input 1 key. The LEDs for Input 1 and Outputs 1, 2, and 3 all flash.

Later, another user connects Input 8 to outputs 1, 2, and 3 over the RS-232 bus. The original user begins experiencing problems and checks the status from the front panel using Key 2. None of the LEDs will flash. This indicates there has been a change in the setup.

NOTE: If the {CLF} command is not used, the front panel LEDs will continue to indicate the last setup made using the front panel. Any changes over the RS-232 bus will be not be indicated. The user controlling the MultiTasker from the RS-232 bus must send the command {CLFC2} to clear the status LED information.

33.{CLFG}

This command is the same as the {CLFC} command except that it clears the memory of input-to-output connections used to flash the LEDs for a group of matrix cards.
