Description:

The RF8135R active RFID receiver module receives data sent from RF8315T modules on 315Mhz supporting up to 160 IDs. This low-cost receiver module requires no external power supply (some pc or notebook may require external 9V power input) and has a range of 8 meters. The unit and compatible RFID transmitters can be ordered in the US from CheaperTronics.

Quirks and Limitations:

None at this time.

Connection Details

The RF8135R uses a serial connection. It can use a standard 9 wire cable or a minimalist 3 wire cable, since it really only uses send, received, and ground wires. The connection parameters are 9600, 8 data bits, 1 stop bit, no parity, and no flow control. The speed is low, but the amount of data is very trivial, so it's not a big issue.

Configuration Files

There is one configuration file that should be created to use the functionality surfaced in this driver. It should be placed in the CQCData\MacroFileRoot\RFID folder (you will need to create the RFID folder). The TAGS.TXT file contains a list of TAG ID (found on the label for each transmitter) and a driver field name that is to be used for that device. The names are used as CQC field names and must confirm to the constraints of field names (e.g. a single word, no special characters etc.) and must NOT be duplicated.

For example:

1234=Keychain

Driver Fields

This section lists the fields that the driver makes available, their types, minimum and maximum values, etc...

Name	Type	R/W	Description/Limits
AutoLearn	Boolean	W	Set to true to have the driver automatically add any heard tag to the configuration file.
ReloadConfig	Boolean	W	Set to true to have the driver reload the configuration file
Status	String	R	Shows the value "OK" if any data is being received or "NO DATA" if not.
TagCount	Card	R	The count of tags (RFID transmitters) defined in the configuration file
<TAGNAME>	Boolean	R	One field is created for each defined tag. The value is True if the tag has been heard within the configured time window, False if not.
