Configuring RevWorks for FARO Serial Digitizers

 

The FARO 3D digitizer requires no hardware configuration for use. When RevWorks first attempts to communicate with a FARO digitizer, RevWorks automatically initializes the serial baud rate and begins communication.

At any time, you can use the Caliper 3D software that comes with the FARO digitizer to change several internally maintained options, such as the coordinate system. For more information on the Caliper 3D software, refer to the Caliper 3D software manual.

To Configure RevWorks for a FARO Digitizer

1. From the RevWorks toolbar, select ,
   or select Options… from the RevWorks menu.

The Options dialog appears.

2. Select the Devices tab.

3. From the Current Device drop-down list box, select FaroSerial.

The Options tab automatically reflects configuration options for the digitizer.

4. In the Options tab, select the communications Port to which you connected the digitizer.

5. In the Options tab, select a Baud Rate of 4800, 9600, 19200, 38400, 57600, or 115200.

Note: RevWorks maintains the communications options that you specify for your FARO digitizer. If you select a baud rate different from the current setting, RevWorks updates the device to use the new baud rate.

6. In the Options tab, select Data Bits to be 8 or 7.

Note: You should not need to change the setting for data bits from its default setting of 8 unless you change the value for parity. If you select 8 data bits, parity must be set to None. If you select 7 data bits, parity must be set to Even.

7. In the Options tab, select Parity to be None or Even.

Note: You should not need to change the setting for parity from its default value of None, unless you change the value for data bits. If you select None for parity, data bits must be set to 8. If you select Even parity, data bits must be set to 7.

8. In the Options tab, select Stop Bits to be 1

Note: Thought presented in a selectable field, the default value for stop bits cannot currently be changed from the default value of 1.

9. Change the default value for the Probe Approach Tolerance if you wish to change probe motion sensitivity.

Note: The Probe Approach Tolerance sets a threshold, above which any movement of the probe tip registers as actual probe motion for the purpose to determining the offset direction for features measured with a ball probe.

10. Select OK to accept the specified options.

Your FARO serial digitizer is now ready to start.

Probe Approach Tolerance

RevWorks tracks probe movement to assist in determining the proper offset direction for features measured with a ball probe. The sensitivity for probe movement may be adjusted by changing the Probe Approach Tolerance. The Probe Approach Tolerance specifies how much the probe must move before that movement registers as probe motion for the sake of determining the offset direction. The default value of 2 millimeters should be adequate for most measurements. If you are measuring features, such as a bore with a ball probe that is nearly the size of the bore, you may want to reduce the Probe Approach Tolerance, if the probe cannot be moved at least the specified amount before the first point is taken. RevWorks may not be able to determine the correct offset direction unless you approach the first point of the feature by at least the distance specified by the Probe Approach Tolerance. If RevWorks seems to be randomly offsetting in the wrong direction, the value for Probe Approach Tolerance may be too small.

Note: RevWorks displays measurements in the same units as the currently active part or assembly document. You can enter values in any other supported unit of measure by adding the recognized abbreviation after the value you enter.
