MULTITASKER™
23.[SID+]
This command sets the Card ID of all cards to their slot number plus the offset value.
Command Format: [SID+n]
n = Offset amount (n = # from 0 to 99) The maximum Card ID is 99, so subtract the highest slot number from 99 to find the maximum offset. For example, in an 8 slot enclosure, the maximum offset would be
91.The slot number, 8, plus the offset, 91, equals 99.
Example:
There are two, 20 slot enclosures to be connected together during normal operation. The first unit will use the default card IDs where the card ID is equal to its slot numbers. The second unit will have the same Unit ID, but each card ID will be offset by 20.
Connect the computer to the second unit only and send [SID+20] to set the ID of all the cards in the enclosure to their slot number plus 20. Reconnect both units to the computer.
The cards in the first unit will be referenced as card IDs
24.[RSN]
This command reads the slot number of the card with a specified ID number, and returns the value to the system to be displayed in the terminal window. If more than one card has the same ID, each slot number will be displayed.
Command Format: [RSNCi]
Ci = Card ID (i = # from 1 to 99)
Example:
The card in slot 4 uses four slots. Its ID was set to C1 since it is the first card in the system, reading from left to right. Send the command [RSNC1] to find the slot number of C1. The system will respond with the following:
[4]
GROUP COMMANDS
The next few commands are group commands. The use of groups allows several boards, with the same functions, to be controlled simultaneously with a single command. These commands apply to all cards, not only the
25.[WR]
This command groups multiple cards in the enclosure allowing all the group members to be controlled simultaneously with the same command. Each MultiTasker™ unit may define a maximum of eight groups.
In MultiTasker™ 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
Command Format: [WRCn1Cn2…GkUi]
Cn = Card ID (n = slot # from 1 to max slots)
Gk = Group number (k = # from
Ui = Unit ID (i = # from
Example:
Group cards 2, 4, and 6 as group 5 of Unit ID 1 by sending the command [WRC2C4C6G5U1]. After executing this command, cards 2, 4 and 6 will be grouped together as group 5 of Unit ID 1. The system will return the following feedback:
[G5=C2C4C6]
Now, when a command is sent to G5, each board in G5 will execute the same command.
26.[RMC]
This command may be used to remove one or more group members from a group. Reset the system after using this command for all changes to take effect.
