MULTITASKER

400-0402-003

17

Command Format: {CLFGk}

Gk = Group number (k = # from 1-8)

See the {CLFC} command for details.

34.  

{STA}

This command is used to show the 
input-to-output connections for Matrix 
cards/groups  as set from the front panel only. 
The LEDs on the front panel flash to show 
connections.

The {STA} command must be programmed into 
a subroutine for the front panel.

NOTE:

This command is used in conjunction 

with the {CLF} command.

Command Format: {WRSy=LED*=0,STA}

Sy = subroutine (n is a # from 1 to 180)

Example:

C4 is an 8X8 matrix card and the following is 
programmed into the front panel:

Keys 13-20 select inputs for C4.

Keys 29-36 select outputs for C4.

Sub 2 contains the following:
{WRS2=LED*=0,STA}.

Key 2 is programmed as follows:
{WRK2=2,0,0,0,0}.

Connect Input 1 to Outputs 1 and 2 on C4 and 
verify the connection. Use the following steps:

1.

From the front panel, connect Input 1 

(Key 13) to Output 1 (Key 29). LEDs 13 and 
29 flash.

2.

Next, connect Input 1 (Key 13) to Output 2 

(Key 30). LEDs 13 and 30 flash.

3.

Press any key and the LEDs stop flashing.

4.

Press Key 2 and then Key 13. LEDs 13, 29,

and 30 flash indicating Input 1 is connected 
to Outputs 1 and 2.

NOTE:

 An input or output key can be selected 

to see its  connections. In either case, all 
connections would be indicated. Selecting an 
input key will show all the outputs to which the 
input is connected. An output key will show only 
the one input to which it is connected.

KEY COMMANDS

Key commands define which subroutines will be 
performed when a key is pressed under various 
conditions and how it will respond to activation. 
Keys may also be given labels to help identify their 
usage.

35.  

{RDK}

This command displays the contents of one or 
more key programs. The subroutines defined 
will be displayed first, then the key label, if any. 
Next, if the key is defined as volume control, the 
word VOLUME will be displayed. Lastly, if the 
key is locked, the word LOCKED will be 
displayed.

Command Format: {RDKn}

Kn = key program (n = # of key program)

{RDKn}:

Display a single key program.

{RDK*}:

Display all key programs.

Example 1:

Display the program definition for Key 1 by 
sending {RDK1} and the system will display the 
program in the following format:

KEY1 : 2,5,10,20,30 LABEL VOLUME LOCKED

KEY1

The key number requested.

2

Go to SUB2 for key state 1.

5

Go to SUB5 for key state 2.

10

Go to SUB10 for key state 3.

20

Go to SUB20 for key state 4.

30

Go to SUB30 for key state 5.

LABEL

The key label text will be displayed if 
a label was defined using {WRLK}.

VOLUME

VOLUME will be displayed if the key 
was set using {SETVK}.

LOCKED

LOCKED will be displayed if the key 
was locked using {LOCK}.
