IviSwtch Attribute Defined Values
| Attribute | Value Name | Defined Value | Description |
|---|---|---|---|
| SCAN_MODE | VAL_NONE | 0 | Indicates that no action should be taken on the previous paths. |
| VAL_BREAK_BEFORE_MAKE | 1 | Tells the device to break the previous paths before making the new paths. | |
| VAL_BREAK_AFTER_MAKE | 2 | Tells the driver to make the new paths before breaking the previous paths. | |
| TRIGGER_INPUT | VAL_IMMEDIATE | 1 | Indicates that the switch module does not wait for a trigger before starting the next entry in the scan. |
| VAL_EXTERNAL | 2 | Indicates that the trigger is coming from an external source through a trigger input connection. | |
| VAL_SOFTWARE_TRIG | 3 |
The trigger is a software command sent by the program though the IviSwtch_SendSoftwareTrigger operation. If you set the IVISWTCH_ATTR_TRIGGER_INPUT attribute to this value, the instrument can only be triggered by calling the IviSwtch_SendSoftwareTrigger function. |

Parameter Defined Values
| Parameter | Defined Value | Description |
|---|---|---|
| pathCapability | IVISWTCH_VAL_PATH_AVAILABLE | Indicates that the driver can create the path at this time. |
| IVISWTCH_VAL_PATH_EXISTS | Indicates that the path already exists. | |
| IVISWTCH_VAL_PATH_UNSUPPORTED | Indicates that the instrument is not capable of creating a path between the channels you specify. | |
| IVISWTCH_VAL_RSRC_IN_USE | Indicates that although the path is valid, the driver cannot create the path at this moment because the switch module is currently using one or more of the required channels to create another path. You must destroy the other path before creating this one. | |
| IVISWTCH_VAL_SOURCE_CONFLICT | Indicates that the instrument cannot create a path because both channels are connected to a different source channel. | |
| IVISWTCH_VAL_CHANNEL_NOT_AVAILABLE | Indicates that the driver cannot create a path between the two channels because one of the channels is a configuration channel and thus unavailable for external connections. | |
| scanMode | IVISWTCH_VAL_NONE | The instrument takes no action on existing connections. |
