MULTITASKER
35.[SDO]
This command detects if there is a signal present on one output or all outputs. The system will return feedback along the following:
Command Format, One Output: [SDOmmCn]
Command Format, All Outputs: [SDOCn]
mm = Output
Cn = Card ID (n = slot # from 1 to max slots)
Feedback Format: [OxxSyCn]
xx = Input number (
y= Signal present (1=signal, 0=no signal) Cn = Card ID (n = slot # from 1 to max slots) Example 1:
Check for a signal on Output 1 of C8 by sending [SDO01C8]. If a signal present on Output 1, the following feedback will be displayed:
[O01S1C08]
Example 2:
Check for a signal on all outputs of C8 by sending [SDOC8]. In the example below, there is a signal is present on Output 1, but the rest have no signals. The
[O01S1C08] [O02S0C08] [O03S0C08]
[O04S0C08] [O05S0C08] [O06S0C08]
[O07S0C08] [O08S0C08] … [O63S0C08] [O64S0C08]
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 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
36.[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.
