Triggering Devices - Wired Control

1238888

The Vantage has an External Sync Output port and an External Trigger-Input port via the Auxiliary Box. Use the External Sync Output port to synchronize measurements with any other controller such as a robot, CNC, or other external device. The External Trigger-Input port enables measurement requests to be initiated via hardware control, such as from PLC equipment. An optional Multi-use Integrator cable (FARO part # C-CBL-08796-000-05 or C-CBL-08796-000-10) is available for the Auxiliary Box to provide access to both ports. The cable has four (4) pairs of shielded wires on the opposite end for connecting to another controller or external device. For more information on setup and operation of the Auxiliary Box, see the FARO Laser Tracker Accessories Manual.

FARO CAM2 2021 , FARO Tracker Utilities Measure Pad, and the FARO Software Developer's Kit support this port.

External Trigger-Input

The External Trigger-Input works by using a +3.3 Volt CMOS (+5 Volt tolerant) input signal. The standard way to do this when using isolated contacts (External Trigger and GND signals) is to have the contacts normally open. This allows the internal 2.74 kΩ resistor to pull the signal up to +3.3V. When the contacts are closed, the input is pulled down to ground making this an active low trigger. When the Auxiliary Box senses this change, it causes the Vantage to record a measurement.

The External Trigger-Input uses the White-Brown and Brown wire pair of the Multi-use Integrator cable. The Brown wire is connected to the internal Auxiliary Box ground and the White-Brown wire is the external trigger signal input.

Only use the Brown wire from the White-Brown and Brown pair for the ground. Using a wire from another pair can cause improper signaling. Isolate the remaining wire pairs to prevent a short circuit.

External Sync-Output

The External Sync-Output is a +3.3V CMOS logic level capable of 24mA drive. To use the CMOS output signal, use the White-Green and Green wire pair of the Multi-use Integrator cable. Connect the Green wire to ground of the external device and connect the White-Green wire to the signal input of the external device. The signal is configured as active low. The signal from the White-Green wire will be below +0.6V when measuring is active and higher than +2.2V when measuring is inactive.

Only use the Green wire from the White-Green and Green pair for the ground. Using a wire from another pair can cause improper signaling. Isolate the remaining wire pairs to prevent a short circuit.
