The Communications dialog sets the serial port parameters for the interface to the FaroArm.

Serial Port Settings
Serial port
Connected serial port (COM1 to COM4).
Baud rate
Speed of data stream (4800 baud to 115200 baud).
Parity
Data stream parity (None, Even).
Data bits
Number of data bits per each byte sent. (7 or 8).
Error tolerance
The higher the error tolerance, the greater the number of retries whenever the application receives erroneous packets from the data stream. The maximum error tolerance setting will cause the program to try to read data from the FaroArm indefinitely.
Sampling rate
This slider controls the number of times per second that Faro will read the position of the digitizer tip. The higher the number, the higher the frequency of reads and updates. Note that continuous mode is not available at the highest baud rates.
