    When a 5 V signal is applied to 5 V tolerant pins, they present a high impedance even if the Rabbit power is off. The 5 V tolerant feature allows 5 V devices that have a suitable switching threshold to be connected directly to the RCM3000. This includes HCT family parts operated at 5 V that have an input threshold between 0.8 and 2 V.

    Either of the two communicating devices can supply the clock. When the Rabbit 3000 provides the clock, the baud rate can be up to 80% of the sys- tem clock frequency divided by 128, or 183,750 bps for a 29.4 MHz clock speed.

    The hub relays packets received on any port to all of the ports on the hub. Hubs are low in cost and are readily available. The RCM3000 board uses 10 Mbps Ethernet, so the hub or Ethernet adapter must be either a 10 Mbps unit or a 10/100 unit that adapts to either 10 or 100 Mbps.

    6.3 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.

  • Page 48: How Ip Addresses Are Used

    Each RCM3000 RabbitCore module has its own unique MAC address, which consists of the prefix 0090C2 followed by the code that appears on the label affixed to the RCM3000 module. For example, a MAC address might be 0090C2C002C0.

If you are not concerned about accessing the RCM3000 from the Internet, you can place the RCM3000 on the internal network using a private address assigned either statically or through DHCP.

  • Page 50: Placing Your Device On The Network

    You can either place the RCM3000 directly on the Internet with a real Internet address or place it behind the firewall. If you place the RCM3000 behind the fire- wall, you need to configure the firewall to translate and forward packets from the Internet to the RCM3000.

    RCM3000 board through header J2. An RCM3000 with no loading at the outputs operating at 29.4 MHz typically draws 145 mA. The RCM3000 will consume an additional 10 mA when the programming cable is used to connect the programming header, J3, to a PC.

  • Page 112: Reset Generator

    The RCM3000 uses a reset generator to reset the Rabbit 3000 microprocessor when the voltage drops below the voltage necessary for reliable operation. The reset occurs between 2.85 V and 3.00 V, typically 2.93 V. The RCM3000 has a reset output, pin 1 on header J2. D.2 Optional +5 V Output The RCM3000 RabbitCore boards have an onboard charge pump that provides the +5 V needed by the RealTek Ethernet chip.

    E.3 Using Parallel Port F Parallel Port F is a byte-wide port with each bit programmable for data direction and drive. These are simple inputs and outputs controlled and reported in the Port F Data Register. As outputs, the bits of the port are buffered, with the data written to the Port F Data Regis- ter transferred to the output pins on a selected timing edge.

    I and Q inputs are sampled in different clock cycles. The Input Capture (see the Rabbit 3000 Microprocessor Users Manual) may be used to measure the pulse width on the I inputs because they come from the odd-numbered port bits.
  • Page 121 The Quadrature Decoder generates an interrupt when the counter increments from 0x00 to 0x01 or when the counter decrements from 0x00 to 0xFF. Note that the status bits in the QDCSR are set coincident with the interrupt, and the interrupt (and status bits) are cleared by reading the QDCSR.
