    6.2 TCP/IP Primer on IP Addresses Obtaining IP addresses to interact over an existing, operating, network can involve a num- ber of complications, and must usually be done with cooperation from your ISP and/or network systems administrator.

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.

  • Page 91: Power Supply

    B.3 Power Supply The RCM3305/RCM3315 requires a regulated 3.15 V to 3.45 V DC power source to oper- ate. Depending on the amount of current required by the application, different regulators can be used to supply this voltage. The Prototyping Board has an onboard +5 V switching power regulator from which a +3.3 V linear regulator draws its supply.

  • Page 97 RS-232 serial communication protocol. Basically, the chip translates the Rabbit 3000’s signals to RS-232 signal levels. Note that the polarity is reversed in an RS-232 circuit so that a +5 V output becomes approximately -10 V and 0 V is output as +10 V.
  • Page 98 3000 Serial Port C through an RS-485 transceiver. The half-duplex communication uses an output from PD7 on the Rabbit 3000 to control the transmit enable on the communica- tion line. Using this scheme a strict master/slave relationship must exist between devices to insure that no two devices attempt to drive the bus simultaneously.

E.1.1 RabbitNet Connections All RabbitNet connections are made point to point. A RabbitNet master port can only be connected directly to a peripheral card, and the number of peripheral cards is limited by the number of available RabbitNet ports on the master.

    With this type of termination, the maximum frequency is limited by the round-trip delay time of the cable. Although a peripheral card could theoretically be up to 45 m (150 ft) from the master for a data rate of 1 MHz, Rabbit recommends a practical limit of 10 m (33 ft).
