2. CP2201EK Overview
The purpose of the CP2201EK is to provide a way to easily evaluate Silicon Laboratories Ethernet Solutions and
view some of the applications made possible by the CP2200/1. To develop embedded applications using the
CP2200/1, we offer a complete Embedded Ethernet Development Kit (Ethernet-DK). The Embedded Ethernet
Development Kit contains a TCP/IP Configuration Wizard that automatically generates code to perform many of the
functions in the CP2201EK. Numerous code and application examples are also provided in the development kit.
The CP2201EK is a fully contained evaluation board. The main system controller, which runs the TCP/IP Stack and
performs other system tasks, is a 50 MIPS Silicon Laboratories C8051F340. The Ethernet controller providing
network connectivity is the Silicon Laboratories CP2201—the industry's smallest Ethernet controller. The third
major component on the board is the Ethernet connector (RJ-45) with integrated magnetics and LEDs.
On the software side, the C8051F340 is running the CMX Micronet Web Server. The embedded web server has
web pages for displaying temperature and light sensor data, controlling the yellow LED state, sending an e-mail,
remotely updating firmware, and displaying images and CP2201 Key Features. The embedded system can also be
accessed through a command line Telnet interface.
Figure 1 shows the CP2201EB and identifies its various components.

Page 2: Hardware Setup
5. Network Setup The CP2201EK software uses the Netfinder utility to find all CP2201EB boards connected to the network. If the network has a DHCP server, then each device will automatically acquire an IP address once it detects that it has been plugged into a live network. - Page 3 CP2201-EK 2. If the CP2201EB was able to automatically obtain an IP address through DHCP, then its IP address will appear inside a window with green background. If the device’s IP address is 0.0.0.1 and the window back- ground is yellow, then skip this step and the following step. If the device was unable to automatically obtain an IP address through DHCP, then its IP address will be 0.0.0.1 and it will appear inside a window with a yellow background.
- Page 4 CP2201-EK 5. If the network does not have a DHCP server, then the CP2201EB will search for approximately 35 seconds before going into static IP address mode. While searching, the yellow led will be blinking fast. After going into static IP address mode, Netfinder will display information about the device in a window with a yellow background.
- Page 5 CP2201-EK 7. Close the ‘Assign IP Address’ dialog then press Search to refresh the Netfinder screen. Select the device by clicking inside the yellow area and pressing the Web Browser quick launch button as shown in Figure 7. Figure 7. Web Browser Quick Launch Button In Static IP Address Mode 8.

Sending an e-mail containing the latest sensor data. Monitoring real-time sensor data using the Telnet interface.
- Page 7 CP2201-EK Clicking the second link on the main web page ‘2. Control Yellow LED’ will load the yellow LED control page shown in Figure 10. Each of the links numbered 1 through 4 on this page borrow the yellow LED for 10 seconds and force it to the state described in the text.
- Page 8 CP2201-EK 6.4. Monitoring Real Time Sensor Data Using the Telnet Interface The temperature and light sensor data can be monitored using the command line Telnet interface. The Telnet interface is very similar to UART, except bytes are sent over a TCP connection instead of an RS-232 cable. 1.
- Page 9 CP2201-EK 6.5. Remotely Updating Firmware Using the Bootloader The CP2201EB has a bootloader that can be used to update its firmware over the network. The bootloader uses the Trivial File Transfer Protocol (TFTP) to transfer an image file from the PC (TFTP Client) to the CP2201EB (TFTP Server).

Below are a few guidelines to follow when choosing an IP address for the embedded system. Figure 20 shows an example of a compatible PC and embedded system IP address combination.
