Sort-of-Networked RFID Reader

A 125Khz RFID Reader with a simple RS232 based ring network - to allow connection of multiple units to the same control computer.

Consider using "RS-232D", aka "EIA/TIA-561". It has all the same wires and voltages as RS-232, but specifies a RJ45 connector.

Also consider RS-485.

(What is the name of the standard for RS-485 on RJ14 ("4 wire RJ-11") or RJ45 ?) (Ethernet? =P)
