MULTITASKER™
400-0132-005
16
Some cards require more than one slot in the
MultiTasker™ system. As an example, some
matrix switcher cards require 4 slots. If there are
five of these cards installed, they would be
numbered C4, C8, C12, C16 and C20.
Changing the Card ID allows the user to define
the cards as C1, C2, C3, C4 and C5.
Another use for changing the Card ID is to be
able to use multiple systems without having to
set each unit to a different Unit ID. All systems
may be left as Unit ID 0 for ease of
programming. The cards in the first unit may be
numbered 1-10 and in the second unit 11-20.
The ID commands work with all MultiTasker™
Front Panel systems. However, front panels that
have firmware releases prior to the following will
not be able to address Card IDs greater than
the number of slots in the system:
690-0122-019 = Version 019 or later.
690-0123-005 = Version 005 or later.
690-0124-019 = Version 019 or later.
Send the command [VER], and the system will
respond with feedback that includes the
following:
690-0122-019 690-0123-005 690-0124-019
Check the last three digits against the numbers
above to determine if the Card ID commands
can address all 99 Card IDs.
20. [RSI]
This command resets the card IDs in the
system. After sending this command, each card
ID in the system will match the slot number of
the card. If the card is moved to another slot, its
ID number will be the new slot number.
Command Format: [RSI]
Example:
Send the command [RSI] to the system with
Unit ID 0. The card in slot 1 will have ID 1, the
card in slot 2 will have ID 2 and so on. If the
card in slot 1 is then moved to slot 4, the card ID
will then be 4.
21. [SIDn]
This command sets all the cards installed in the
MultiTasker™ system to the same Card ID.
After sending this command, all cards will be
addressed with the same ID. Use caution when
sending this command to a system with multiple
board types.
Command Format: [SIDn]
n = Card ID (n = # from 1 to 99)
Example:
Send the command [SID1] to the system. All the
cards in the system now have ID 1. Any
commands that are sent to Card ID 1 will be
received and executed by each card.
22. [SIDnCi]
This command sets the Card ID of a single card
to a number from 1 to 99.
Command Format: [SIDnCi]
n = Card ID (n = # from 1 to 99)
Ci = Slot Number (i = # from 1 to max slots)
Example:
Send the command [SID50C10] to set the ID of
the card in slot 10 to an ID of 50.
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.
