This LBS integrates the RSS-Systems RFID reader (http://www.rss-systems.de/sr28.pdf)
Prerequisites: TCP/IP connection to RFID reader via ser2net or an RS485/232-IP Adapter
With E5/E6 you can add/delete RFID transponder IDs. E4 defines a MASTER Trandponder ID.
When the reader reads the MASTER transponder, the LBS switches in MASTER mode for 15 seconds.
While in MASTER mode and reading another transponder ID, this ID will be added to authorized
transponder list, if it does not exists already. Otherwise it will be deleted from the list
of authorized transponders.
Sending a 1 on E7 will generate a list of all authorized transonders on A7.
E8 specifies the grace period in seconds. After that time receiving the same transponder ID as before
is recognized as a new authorization. All identical IDs before that time period are recognized as duplicates
and will be ignored.
E1: Start (1) / Stop (0) RFID Reader
E2: IP Adress of ser2net or RS485/IP Adapter
E3: Port used by ser2net or RS485/IP Adapter
E4: ID of Master key, which can be used to add/delete transponder
E5: 10 byte code to be added to list of authorized transponder
E6: 10 byte code to be deleted from authorized transponder list
E7: 1 on this inputs generated a full list of authorized codes on A7
E8: Grace period after which a transponder triggers a second event
E9: specifies the length of the RFID tag identifier in bytes
E10: specifies the character to identify the start of RFID tag identifier (default: space)
E11: Enable Logging (0-none|1-emerg|2-alert|3-crit|4-err|5-warning|6-notice|7-info|8-debug)
A1: Status of Reader: 0-Stopped | 1-Normal Operation | 2-Master Mode
A2: Last transponder ID received
A3: Timestamp when last transponder ID was received
A4: Authentication successfull (1) => This signal should trigger e.g. the door opener
A5: Authenticated transponder ID
A6: Time of last authentication
A7: List of valid transponder IDs [[name][ID]][[name][ID]]...[[name][ID]]
A8: Last error code (1-mysql connection error)
V1 : Indicator whether LBS is running (1) or not (0)
V2 : message queue ID
V100: Version of LBS
V101: LBS Number
V102: Name of Custom Log
V103: used to store Loglevel

- Install php-process
Install php-process extension:
==============================
Login in as root to your EDOMI Server and execute the following command:
yum install php-process
Changelog:
==========
v0.1: Initial version
v0.2: LBS extended by two inputs to specify length of RFID Code (E9) and delimiter byte to identify start of RFID code (default: space)
