R/W | N/A | None | IviSwtch Configure Scan List |
Description
This property specifies what happens to existing connections that conflict with the connections you make in a scan list. For example, if CH1 is already connected to CH2 and the scan list instructs the switch module to connect CH1 to CH3, this property specifies what happens to the connection between CH1 and CH2.
If the value of this property is IVISWTCH_VAL_NONE, the switch module takes no action on existing paths. If the value is IVISWTCH_VAL_BREAK_BEFORE_MAKE, the switch module breaks conflicting paths before making new ones. If the value is IVISWTCH_VAL_BREAK_AFTER_MAKE, the switch module breaks conflicting paths after making new ones.
Most switch modules support only one of the possible values. In such cases, this property serves as an indicator of the module's behavior.
IVISWTCH_VAL_BREAK_BEFORE_MAKE—tells the driver to break the previous paths before making the new paths.
IVISWTCH_VAL_BREAK_AFTER_MAKE—tells the driver to make new paths before breaking the previous paths.
IVISWTCH_VAL_NONE_for_SCAN_MODE—indicates that no action should be taken on the previous paths. You must support at least one value to support this property.
