LED COMMANDS
LED commands apply to the
MT101-115/117
only
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.

{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.
