FARO Laser Scanner Photon – User’s Manual
83 / 87
All signal outputs are open collectors.
Incoming signals should have a minimum duration of 40ns. The scanner is
triggered on the falling edge of the signal (active low). It handles incoming
signals only when it is ready and if it is set to external control mode. If the
scanner is not set to external control mode, the scanner doesn’t wait for an
incoming start signal to start scanning. It will scan immediately when it gets
ready.
The scanner signals its readiness with a high level on pin [Ready].
When the scanner is recording (ready & start signal detected), on each turn
of the mirror a sync signal of 0.1ms duration will be created.

Test device
When you have purchased the helical option a test device will be supplied
together with the FARO LASER SCANNER PHOTON. This test device can be
connected to the helical socket (see 10.3.3). It is for testing the scanner’s
helical mode and to demonstrate the functionality of this mode.
