Editing RFID Reader

=== 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 [http://zytrax.com/tech/layer_1/cables/tech_rs232.htm#rj45 "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)

The company says the Mercury4 can read any RFID tag format, including those not yet invented". The TI 5502 DSP running "MercuryOS" runs the software-defined radio (SDR). The Intel IXP420 running Linux runs the web server hosting the remote configuration interface.
