SyncDriver

The sync driver has two functions. It serves as a provider for ‘dummy’ axes and it can do a low-accuracy sync with external devices by stopping the measurement until a certain event has occurred on a serial-port line or by triggering an external device by setting a serial-port line low or high.

Active Syncing

The SyncDriver cannot provide a pixel clock. It can, however set the output lines of the computers RS232 to high or low or pulse them in arbitrary sequences along the measurement axes. The triggering is set up through the ‘TTL’ property sheet in the measurement settings and follows the standard TTLChannels scheme (ref{sec:TTLChannels})
