Standard Actions
So far, i!-ConnectLinx has handled custom actions where each action is likely to
be different from system to system. In the Using i!-ConnectLinx example on
page 84, action 1 played the VCR. However, in another system, it is very unlikely
that action 1 plays the VCR.
i!-ConnectLinx uniquely identifies each action list. Once an i!-ConnectLinx
compatible technology programs itself to execute an action on a system, it also
stores a copy of the system identifier from the action list. This identifier is sent to
i!-ConnectLinx along with this action execution request. If the action identifier
does not match the i!-ConnectLinx system that received the request, the action is
not executed. This eliminates any ambiguity that may exist, since each system’s
action 1 may be different.
i!-ConnectLinx supports standard actions. Standard actions are actions defined
by AMX and supported natively by i!-ConnectLinx. When adding actions to
i!-ConnectLinx, it is best to use the standard action if it is available. That way, the
action can be executed regardless of which system the i!-ConnectLinx
compatible technology was programmed to control.
The list of standard actions are listed in the i!-ConnectLinxStdFunctionList.xls
file. The standard actions ID are the same as the channel number used to execute
the action. For instance, VCR Select has an ID of 1011 so the programming to
support this standard action is:
BUTTON_EVENT[vdvCLActions,1011] (* VCR Select *)
{
PUSH:
{
// Switch the projector and switcher to select the VCR
}
}
To add a standard action, look up the action ID in the Standard Function List file,
and send that in a send command to i!-ConnectLinx to tell it you want to support
that action. To change the above example to standard action:
1. Lookup VCR Play and VCR Stop in the Standard Function List.
2. Find their IDs. VCR Play is 1131, and VCR Stop is 1132.
3. Send the IDs to i!-ConnectLinx:
DATA_EVENT[vdvCLActions]
