	~~== v1.1.3 ==~~

	* [[NA v1.1.3]]

	~~Availability of parts forced a slight change from v1.1.2 to this version:~~

	* Based on the [[Arduino]] [http://arduino.cc/en/Main/ArduinoBoardDuemilanove Duemilanove] using the [http://arduino.cc/en/Main/ArduinoEthernetShield Ethernet Shield] for communication.
	* Arduino's digital pins #2-9 set to output through 330Ω resistors to 2x [[LTV-846]] opto-isolators which opens and closes a given node's reset switch. Supports up to 8 nodes at the moment.
	* [[74HC540E]] 8-Input Inverter for the status LEDs.
	* [[1N4148]] diodes prevent improper connection of the reset connectors by providing a closed circuit when the reset switch's +5vcc is connected to the ground pin.
	* 8x green and 8x red low-power LEDs are are paired up per circuit to show the status of each port.
	* 16x 330Ω resistors. Each Open/Fenced status LED pair's grounds are tied together and connected to ground via a resistor and the Arduino pins going through the optoisolators are tied to ground through a resistor.
	* An Arduino [[Proto Shield v.4]] is used to assemble the components onto an Arduino-compatible shield. Given the size restrictions, wire-wrap wire is used to provide connections. It's messy, but it works.
