7.3 Detailed command descriptions:
Cycle Time Set
Cycle time is set by transmitting the number of 0.01 second increments needed to make the
desired output rate. The default rate is 10 hertz (C0010). To set the output rate to 1.2
seconds the command string would be "C0120".
After the initial software release another character was added to allow the cycle time to be
set to 5 ms resolution. To maintain compatibility with older versions this character is
optional. For an example on using this extra precision, the command "C00125" would set
the cycle time to 8 hertz (125 ms).
