Initial Research Start from center and work out Start from center and work out We need a central controlling unit to process input from door readers We need a central controlling unit to process input from door readers How will we communicate with it and over what medium? How will we communicate with it and over what medium? How will we process the input once it is received? How will we process the input once it is received?

Central Controller Communication Options Communication Options Serial – dominant but outgoing Serial – dominant but outgoing Ethernet (TCP/IP) – incoming standard Ethernet (TCP/IP) – incoming standard Wireless (TCP/IP) – very rare but possible Wireless (TCP/IP) – very rare but possible Choice: Ethernet with TCP/IP Choice: Ethernet with TCP/IP Allows Power-Over-Ethernet (POE) Allows Power-Over-Ethernet (POE) Inexpensive and meets fire code Inexpensive and meets fire code No runs more then 100m in building No runs more then 100m in building Allows for secure closed system Allows for secure closed system Follows modular design requirement Follows modular design requirement
