I plugged it into my MAC Book (Arduino Ethernet out to USB in)
// Connect your Arduino Uno to your ComputerUse the USB cable provided in the SIK kit to connect the Arduino to one of your computer's USB inputs.
Arduino Ethernet out to USB in
ProgrammingIt is possible to program the Arduino Ethernet board in two ways: through the 6 pin serial programming header, or with an external ISP programmer.The 6-pin serial programming header is compatible with FTDI USB cables and the Sparkfun and Adafruit FTDI-style basic USB-to-serial breakout boards including the Arduino USB-Serial connector. It features support for automatic reset, allowing sketches to be uploaded without pressing the reset button on the board. When plugged into a FTDI-style USB adapter, the Arduino Ethernet is powered off the adapter.You can also program the Ethernet board with an external programmer like an AVRISP mkII or USBTinyISP. To set up your environment for burning a sketch with a programmer, follow these instructions. This will delete the serial bootloader, however.All the Ethernet example sketches work as they do with the Ethernet shield. Make sure to change the network settings for your network.
I wonder why the SparkFun SIK guide has it pictured that way and has it as part of the step by step...
Can you paste a link to the adapter I need to get?
Also, notice my screenshot of the Serial Port sub menu? Why am I only listing BlueTooth?
