MULTI-TASKER™
14
13. [ + ] and [ – ]
These commands are used to adjust the
Equalization and Horizontal Position and may
be used from keyboard commands or
programmed front panel buttons.
Command Format: [ + ], [ - ]
[+] = Increment level by one step
[-] = Decrement level by one step
Example:
Select the Horizontal Position control for the
card in slot #4. The current setting is 5, but it is
not the optimal value. After sending the
following commands, an optimum setting of 10
is obtained:
1. [EQC4]
The current level is 5.
2. [ – ] [ – ] [ – ]
The level is now 2 and is too low.
3. [ + ] [ + ] [ + ] [ + ] [ + ] [ + ] [ + ] [ + ]
The level is now 10 and no further
adjustments are required.
14. [HELP]
This command displays information available
for the Multi-Tasker interface commands.
Command Format: [HELPCnUi]
Cn = Card ID (n = # from 1 to max slots)
Ui = Unit ID (i = # from 0 to 9)
Example:
In order to display the RS-232 commands
available for the MT103-127/128 card in slot #4,
send the command [HELPC4]. The commands
along with a brief description will be displayed
in the Terminal Window.
15. [WR]
This command groups multiple cards in the
enclosure allowing all the group members to be
controlled simultaneously with the same
command. Each unit may define a maximum of
eight groups.
In Multi-Tasker™ systems with audio and video
cards, boards are typically grouped as follows:
Group 1 = Video Cards
Group 2 = Audio Cards
Group 3 = Video and Audio Cards
If assigning group commands to button
functions, it is best to use the "Press and Hold
on Power Up" to make group settings.
Command Format: [WRCn…GkUi]
Cn = Card ID (n = slot # from 1 to max slots)
Gk = Group ID (k = # from 1-8)
Ui = Unit ID (i = # from 0-9)
Example:
To group cards 1, 2, and 3 as group 5 of
Unit ID 1, send the command
[WRC1C2C3G5U1]. After executing this
command, cards 1, 2 and 3 will be grouped
together as group 5 of Unit ID 1. The system
will return the following feedback:
G1=C1C2C3
Now, when a command is sent to G1, each
board in G1 will execute the same command.
16. [CLRG]
This command clears the members for a single
group or for all groups. The clear command
restores the cards to default settings.
Command Format: [CLRGkUi]
Gk = Group ID (k = # from 1-8, or [ for all)
Ui = Unit ID (i = # from 0-9)
Example:
1) To clear group 1, send the [CLRG1U1]
command. This command clears the
members for the specified group only.
2) To clear all groups of Unit ID 1, send the
[CLRG[U1] command.
NOTE: Since this command is sending the
[CLR] command to its group members,
each card will display its own reset
message.
