 +    1x VT220 Terminal
 +    1x USB RFID
 +    1x Strømstik
 +    ​
 +=== RS485 communication ===
 +
 +Example implementation http://​pskillenrules.blogspot.com/​2009/​08/​arduino-and-rs485.html
 +
 +The MAX487 chip only allows half-duplex. This means that the receiver and transmitter must switch between RX and TX mode internally as well as on the enable pins on the level-converter.
 +
 +The protocol will be [[wp>​Modbus|Modbus RTU]] for which many [[http://​en.wikipedia.org/​wiki/​Modbus#​Open-source_software|implementations]] exists. The server ("​grisen"​) will be the master.
 +
 +=== Bus connection ===
 +Pin out for the [[http://​en.wikipedia.org/​wiki/​Modular_plug#​8P8C|8P8C modular plug]] socket in the server box ("​Grisen"​).
 +
 +^**Position**^ **Use** ^ **Colour code for EIA-568-B** ^
 +|Pos. 1 | ++ (12 V dc) | Orange/​white |
 +|Pos. 2 | ++ (12 V dc) | Orange |
 +|Pos. 3 | --  (Common) | Green/​white |
 +|Pos. 4 | "​X-"/​inverting | Blue |
 +|Pos. 5 | "​X+"/​non-inverting | Blue/​white |
 +|Pos. 6 | -- (common) | Green |
 +|pos. 7 | Not connected | Brown/​white |
 +|pos. 8 | Not connected | Brown |
 +
 +The Cat5e cable going to the front door is wired by the  [[http://​en.wikipedia.org/​wiki/​TIA/​EIA-568-B#​Wiring|EIA-568-B]] colour code, whereas the other cables in the structured cabling uses [[http://​en.wikipedia.org/​wiki/​TIA/​EIA-568-B#​Wiring|EIA-568-A colours]].
 +
 +
 +=== Registers ===
 +The door-arduino has the following registers:
 +  1. status
 +  2. rfid
 +  ...
 +  x. pincode1-4
