Disabling Unused Extensions
IviSwtch Class Driver
When you call the IviSwtch_Connect_Channels, the IviSwtch_SetPath, or the IviSwtch_InitiateScan function, the class driver disables extension capability groups that the program does not use by setting properties of the unused extension group to values that disable that extension group.
If you do not use the IviSwtchScanner extension group, the driver uses the following default values.
| IVISWTCH_ATTR_SCAN_LIST | "" (Empty string) |
| IVISWTCH_ATTR_TRIGGER_INPUT | IVISWTCH_VAL_IMMEDIATE |
| IVISWTCH_ATTR_SCAN_ADVANCED_OUTPUT | IVISWTCH_VAL_NONE |
| IVISWTCH_ATTR_SCAN_DELAY | 0 |
