Page 5: Chapter 1. Introduction & Overview
1. I & O NTRODUCTION VERVIEW The RCM2100 series is an advanced line of modules that incor- porates the powerful Rabbit 2000 ® microprocessor, flash mem- ory, static RAM and an RJ-45 Ethernet port, all on a PCB the size of a business card. Throughout this manual, the term RCM2100 refers to the complete series of RCM2100 RabbitCore modules unless other production models are referred to specifically. -
Page 6: Standard Ethernet Versions
1.1.1 Standard Ethernet Versions There are two RCM2100 models that incorporate an RJ-45 Ethernet port: RCM2100. The RCM2100 is the most fully equipped module in the family, with an Ethernet port, 512K flash memory, and 512K static RAM. The Ethernet port uses some of the Rabbit 2000 microproces- sor’s parallel ports, reducing the available number of I/O pins to 34. - Page 7 The RCM2100 modules have two 40-pin headers to which cables can be connected, or which can be plugged into matching sockets on a production device. The pinouts for these connectors are shown in Figure 1 below. PB1-CLKA PCLK BA12 BA11 BA10 VBAT VRAM...

Page 30: Sample Program Descriptions
3.3.4 Sample Program Descriptions 3.3.4.1 FLASHLED.C This program is about as simple as a Dynamic C application can get—the equivalent of the traditional “Hello, world!” program found in most basic programming tutorials. If you are familiar with ANSI C, you should have no trouble reading through the source code and understanding it. - Page 31 3.3.4.2 FLASHLEDS.C In addition to Dynamic C’s implementation of C-language programming for embedded systems, it supports assembly-language programming for very efficient processor-level control of the module hardware and program flow. This application is similar to , but uses assembly language for the low-level port FLASHLED.C TOGGLELEDS.C control within cofunctions, another powerful multitasking tool.

Page 37: Tcp/Ip Primer On Ip Addresses
4.2 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. For this reason, it is suggested that the user begin instead by using a direct connection between a PC and the RCM2100 board using an Ethernet crossover cable or a simple arrangement with a hub. - Page 38 Hub(s) Firewall Internet Network of Adapter Proxy Workstations Server Ethernet Ethernet RCM2100 Typical Corporate Network Board If your system administrator can give you an Ethernet cable along with its IP address, the netmask and the gateway address, then you may be able to run the sample programs with- out having to set up a direct connection between your computer and the RCM2100 board.

Page 39: Ip Addresses Explained
4.3 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 40: How Ip Addresses Are Used
4.4 How IP Addresses are Used The actual hardware connection via an Ethernet uses Ethernet adapter addresses (also called MAC addresses). These are 48-bit addresses and are unique for every Ethernet adapter manufactured. In order to send a packet to another computer, given the IP address of the other computer, it is first determined if the packet needs to be sent directly to the other computer or to the gateway. -
Page 41: Dynamically Assigned Internet Addresses
4.5 Dynamically Assigned Internet Addresses In many instances, there are no fixed IP addresses. This is the case when, for example, you are assigned an IP address dynamically by your dial-up Internet service provider (ISP) or when you have a device that provides your IP addresses using the Dynamic Host Configu- ration Protocol (DHCP). -
Page 42: Placing Your Device On The Network
4.6 Placing Your Device on the Network In many corporate settings, users are isolated from the Internet by a firewall and/or a proxy server. These devices attempt to secure the company from unauthorized network traffic, and usually work by disallowing traffic that did not originate from inside the net- work. -
Page 43: Running Tcp/Ip Sample Programs
4.7 Running TCP/IP Sample Programs We have provided a number of sample programs demonstrating various uses of TCP/IP for networking embedded systems. These programs require you to connect your PC and the RCM2100 board together on the same network. This network can be a local private net- work (preferred for initial experimentation and debugging), or a connection via the Internet. -
