External SYNC - Remote Input Trigger Wiring for the Vantage Laser Tracker

External SYNC / Remote Input Trigger Port

The Vantage MCU has an External SYNC port or Trigger Cable Port that can be used to synchronize measurements with another controller, such as a robot, CNC, or other external device.  An optional shielded MultiUse Integrator Cable is available that connects directly into this port and has 4 pairs of wires on the opposite end is used for these functions.

Remote Triggering of Tracker Measurements

The trigger input to the MCU works by using a +5 Volt TTL signal. The standard way to do this when using isolated contacts is to have the contacts Normally Closed and supplying +5V to the trigger input. When the contacts are opened, the input is pulled down by an internal 50 Ohm resistor making this an active low trigger. When the MCU senses this change, a measurement is taken.

To trigger a measurement, FARO Technologies recommends opening the contacts for at least 1ms. The MCU will take subsequent measurements for as long as the contact remains open.

The TTL Trigger uses the Green and Black wire pair of the MultiUse Intergrator Cable.  Connect the Black wire to ground and connect the Green wire to a voltage source of at least +3.3V.  Be sure to use the Black wire from the Green-Black pair.  If a Black wire from another pair is used, triggering will not properly occur.  Isolate the remaining wire pairs so they do not short out.

CAM2 software, FARO Utilities Measure Pad, and the FARO Software Developer's Kit support the Remote Trigger.

Using the Tracker to Signal Another Device

There are two options to for the tracker to signal to another device that a measurement has started, TTL and RS485 Differential.

To use TTL output signal, the Red and Black wire pair of the MultiUse Intergrator Cable are used.  Connect the Black wire to ground and connect the Red wire to the input device.  Be sure to use the Black wire from the Red-Black pair.  If a Black wire from another pair is used, signaling will not properly occur.  Isolate the remaining wire pairs so they do not short out.  The signal from the Red wire will be between +3.3 V and + 5 V when measurements are not triggered and lower than +3.3 V when measurements are.

To use RS485 Differential, the Blue and Black pair of the MultiUse Intergrator Cable are used as an RS485 driver which provides a minimum 2 Volt differential output into a 100 Ohm load.  The Black wire is – and the Blue wire is +.  Be sure to use the Black wire from the Blue-Black pair.  If a Black wire from another pair is used, signaling will not properly occur. Isolate the remaining wire pairs so they do not short out.
