CP2201-EK

3. Hardware Setup

The only external hardware connections required by the CP2201EB are power and a connection to a network. All
required system configuration is performed over the network, saving the board space and cost of an LCD screen or
dedicated UART interface.
1. Connect the CP2201EB to an unused Ethernet jack using the blue straight-through cable. This can be a
wall outlet or an empty port on a network router or switch. If an Ethernet outlet is not available, the CP2201
can be directly connected to a PC using the yellow crossover cable.
See Appendix A for additional setup instructions if using a crossover cable.
2. Power the CP2201EB using the universal power adapter supplied with the kit.
3. Wait until the yellow LED turns to solid yellow (not blinking), stops blinking (always on), or starts to blink
intermittently (blink twice then pause).

4. Software Setup

The included CD-ROM contains all CP2201EK documentation, the Netfinder utility, and a firmware image that can
be used for evaluating the Ethernet bootloader. To get started, insert the CD-ROM into your PC's CD-ROM drive
and click "Netfinder." Follow the on-screen instructions when the blue dialog automatically launches. If the dialog
does not automatically appear on the screen when you insert the CD-ROM, run autorun.exe found in the root
directory of the CD-ROM.

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. If there are multiple CP2201EB boards on the network, the Netfinder utility allows
the user to identify the desired device based on the time powered, time plugged into network, MAC address, or IP
address.
