The first two options permit total freedom of action in selecting network addresses and use of the “network,” as no action can inter- fere with other users.

    For this reason, it is suggested that the user begin instead by using a direct connection between a PC and the RCM3305/RCM3315 using an Ether- net crossover cable or a simple arrangement with a hub. (A crossover cable should not be confused with regular straight through cables.)

    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.

    Internet IP address. The host would either translate the data, or it would act as a proxy. Each RCM3305/RCM3315 RabbitCore module has its own unique MAC address, which consists of the prefix 0090C2 followed by a code that is unique to each RCM3305/ RCM3315 module.

  • Page 61: Dynamically Assigned Internet Addresses

    The DHCP server may try to give you the same address each time, but a fixed IP address is usually not guaranteed. If you are not concerned about accessing the RCM3305/RCM3315 from the Internet, you can place the RCM3305/RCM3315 on the internal network using an IP address assigned either statically or through DHCP.

  • Page 62: Placing Your Device On The Network

    If you want users on the Internet to communicate with your RCM3305/RCM3315, you have several options. You can either place the RCM3305/RCM3315 directly on the Internet with a real Internet address or place it behind the firewall.

    The Prototyping Board included in the Development Kit makes it easy to connect an RCM3305/RCM3315 module to a power supply and a PC workstation for development. It also provides some basic I/O peripherals (RS-232, RS-485, a relay, LEDs, and switches), as well as a prototyping area for more advanced hardware development.

    —Two momentary-contact, normally open switches are con- • nected to the PG0 and PG1 pins of the RCM3305/RCM3315 module and may be read as inputs by sample applications. Four user LEDs (DS3–DS6) are connected to alternate I/O bus pins PA0–PA3 pins of the RCM3305/RCM3315 module via U8, and may be driven as output indicators.

    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.

    The Prototyping Board is actually both a demonstration board and a prototyping board. As a demonstration board, it can be used with the sample programs to demonstrate the func- tionality of the RCM3305/RCM3315 right out of the box without any modifications. The Prototyping Board pinouts are shown in Figure B-4.
