Description
This attribute specifies the source of the trigger for which the switch can wait when processing a scan list. The switch waits for a trigger when it encounters a semicolon in a scan list. When the trigger occurs, the switch advances to the next entry in the scan list.

Notes
- (1) NISWITCH_VAL_IMMEDIATE Immediate Trigger. The switch does not wait for a trigger before processing the next entry in the scan list.
- (2) NISWITCH_VAL_EXTERNAL External Trigger. The switch waits until it receives a trigger from an external source through the "trigger in" connector.
- (3) NISWITCH_VAL_SOFTWARE_TRIG The switch waits until you call the niSwitch_SendSWTrigger function.
- (111) NISWITCH_VAL_TTL0 The switch waits until it receives a trigger on the SCXI or PXI_TRIG0 line before processing the next entry in the scan list.
- (112) NISWITCH_VAL_TTL1 The switch waits until it receives a trigger on the PXI_TRIG1 line before processing the next entry in the scan list.
- (113) NISWITCH_VAL_TTL2 The switch waits until it receives a trigger on the SCXI or PXI_TRIG2 line before processing the next entry in the scan list.
- (114) NISWITCH_VAL_TTL3 The switch waits until it receives a trigger on the PXI_TRIG3 line before processing the next entry in the scan list.
- (115) NISWITCH_VAL_TTL4 The switch waits until it receives a trigger on the PXI_TRIG4 line before processing the next entry in the scan list.
- (116) NISWITCH_VAL_TTL5 The switch waits until it receives a trigger on the PXI_TRIG5 line before processing the next entry in the scan list.
- (117) NISWITCH_VAL_TTL6 The switch waits until it receives a trigger on the PXI_TRIG6 line before processing the next entry in the scan list.
- (118) NISWITCH_VAL_TTL7 The switch waits until it receives a trigger on the PXI_TRIG7 line before processing the next entry in the scan list.
- (125) NISWITCH_VAL_PXI_STAR The switch waits until it receives a trigger on the PXI STAR trigger bus before processing the next entry in the scan list.
- (1000) NISWITCH_VAL_REARCONNECTOR The switch waits until it receives a trigger on the Rear connector before processing the next entry in the scan list. This value is valid for SCXI scanners that consist of a single device. If more than one device is used, you must use niSwitch_RouteTriggerInput or niSwitch_RouteScanAdvancedOutput functions to route a trigger from the connector on another module to one of the TTL lines instead.
- (1001) NISWITCH_VAL_FRONTCONNECTOR The switch waits until it receives a trigger on the front connector before processing the next entry in the scan list. When using SCXI scanners, this variable is valid for scanners that consist of a single device. If more than one device is used, you must use the niSwitch_RouteTriggerInput or niSwitch_RouteScanAdvancedOutput functions to route a trigger from the connector on another module to one of the TTL lines instead.
