ID COMMANDS
The default card ID is the same as the card slot
number. The next several commands allow the
user to change the card ID to a value other than
the slot number. Once the ID is changed,
moving the card to another slot will not change
the card ID. If a card in slot 4 is set to ID 1, then
moved to slot 10, its ID will remain 1. The [RSI]
command forces each installed card to take its
slot number as its ID number, regardless of the
slot in which it is installed.
Some cards require more than one slot in the
MultiTasker system. As an example, some
matrix switcher cards require 4 slots. If 5 of
these cards are installed, they would be
numbered C4, C8, C12, C16, and C20.
Changing the 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
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] to the system and the
feedback will include 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.
31.
[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.
32.
[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.
33.
[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.
