Beam rest can be manually overridden as needed. Choose between:
ADM Only. This mode restricts beam tracking operations to ADM only.
IFM Only. This mode restricts beam tracking operation to IFM only which requires a homing procedure each time the beam is broken.
IFM Set by ADM. Faro’s default mode which is a hybrid mode that provides accurate tracking using IFM and easy beam re- capture using ADM modes.
External Trigger Settings. The external trigger will apply to ANY measurement profile which has either a spatial or temporal scan as it’s Acquisition.
When “External” is set (for the Measurement Start Trigger in the Faro Tracker Settings), points will be taken when the trigger is pulsed. The only requirements is that a profile must be started for the external trigger to be recognized which as an Acquisition mode of either spatial or temporal scan. The advantage of this design is that no adjustments to the measurement profile need to be made, and any profile will work (Figure 3-75).
The trigger cable must be connected to the “Up” port on the tracker controller.
0 Volts on the trigger port implies take data and send the data in continuous mode (where as 5 Volts indicates stop). So by default the external trigger is set to on and sending data and must be powered to stop sending data. This means that if there is no external trigger, the measurement will simply begin at the maximum temporal rate of the trackers.
Faro’s video camera is used is used for reflector acquisition and provides a couple of optional modes:
Camera Search Enabled. This option enables camera search. Disabling this option is used to limit target search to a beam spiral search only.
Find Me Enabled. This is similar to the “Gesture Recognition” setting and allows the tracker to snap to the moving target.
Active Seek Radius. Active Seek can be set from main window (formerly “Smart Find”) dialog if supported. The Active Seek Radius can be set to limit the search zone relative to the current beam position considered by the camera.
Data buffering was added to ensure that SA keep up with data delivered form the instrument. With a very tight scan increment this can be quite fast (~100Hz).
Enable Faro Data Buffering. Provides a switch to enable or disable data buffer. If unchecked, behavior is unchanged from previous versions
Buffer Size. Default is 0.2. At 0.2, for a spatial increment of 0.01” (2.54 mm), the buffer would be 0.2/0.01 = 20 pts. Another way to look at this is the Buffer Size means the number of inch- es worth of data that will get buffered. So at a value of 1.0 and a spatial increment of 0.01”, the buffer size would be 1.0/0.01 = 100 pts, and with a point every 0.01”, 100 of them takes up 1.0 inch.
Do not buffer if increment is >= . This allows you to set a maximum increment for which buffering will occur. The default value is 0.1, meaning that when you set a spatial increment of 0.1” (2.54 mm) or higher, no buffering will occur.
Its important to know that this buffering happens on the Faro side, the interface will not receive any data until the buffer is filled. So for example, you cannot set a scan whose increment would result in a calculated buffer size of 100 points, and yet set a profile to stop at 20 points because it will not send data at all until 100 points have been recorded.
