    6.2.1 IP Addresses Explained IP (Internet Protocol) addresses are expressed as 4 decimal numbers separated by periods, for example: 216.103.126.155 10.1.1.6 Each decimal number must be between 0 and 255. The total IP address is a 32-bit number consisting of the 4 bytes expressed as shown above. A local network uses a group of adja- cent IP addresses.

    The RCM3209/RCM3229 has a 2-channel quadrature decoder and a 10-bit free-running PWM counter with four pulse-width registers. These features allow the RCM3209/ RCM3229 to be used in a motor control application, although Rabbit does not offer the drivers or a compatible stepper motor control board at this time.
