RFID InterrogatorThe RFID interrogator is available with serial (RS232) and USB1.1 interface. The device API allows the RF field to be turned
on/off and provide status and version information. The RFID command-set includes block read, block write and transponder
inventory (enumerate IDs of all transponders in range) commands. The interrogator can issue addressed commands (affect only
one transponder) and non-addressed commands (obeyed by all transponders in range).
C++ class libraries and headers are available for Linux and Windows programming environments in statically and dynamically
linked assemblies. Full protocol documentation is available on request. The libraries also support digital signatures, based
on strong encryption, to detect tampering with (and corruption of) data on the transponders. GR1xx Interrogator
| Interface (RS232): MOLEX 6/4 plug (or 9-pin data + power lead via GR2xxx adaptor below)
Interface (USB): USB "B" socket
Dimensions:178x122x36 mm (serial version has 50mm flexible fly lead protruding perpendicularly from centre of one 122x36mm face)
Weight: approximately 200g
Surface texture: matt (black or white)
Power supply: 5V DC, integral to fly lead (serial), bus-powered (USB)
Input current: 350mA
Range (read): 115mm
Range (write): 110mm
Splash resistant: yes, wipe clean with damp cloth
Available in black or white finish. Differently sized and shaped cases are available on request. This device emits radio frequency (RF) radiation at 13.56MHz. The output power level is below the UK Radiocommunications
Agency threshold for licensed operation: you do not need a license to operate this equipment. | GR2xxx Adaptor | Breakout adaptor for RS232 reader: splits the interrogator's output into separate power (DIN5/180) and data (9-pin serial).
The device is enclosed in a 60x30x10mm matt black plastic box. A 9-pin null-modem serial lead (5<=>5, 2<=>3, 3<=>2) and
a 5V power supply are required. |
Technical InformationThe RS232 and USB readers interrogate "high frequency" (13.56MHz) RFID transponders. Five classes of transponder are supported
(each operates an "interrogator-talks-first" protocol):
Texas Instruments Tag-IT (TM) Philips Semiconductors iCODE*1 (TM) ISO 15693 compatible transponders Microchip Series 300 (TM) Inside Technologies PicoTag (TM) and PicoPass (TM) Static and dynamic C++ class libraries and header files for reading and writing to RFID transponders are available for Linux
and Win32 environments. Command-line tools for reading and programming are also available. Please contact us for details.
Digital signature support is also available (in most countries).
Serial communications parameters: 9600,8,N,1 no handshake
USB: device is a bus-powered "standard" speed USBv1.1 device which appears to Windows and Linux as a USB serial port. Windows
2000 family operating systems include the required driver; Linux users should compile the USB serial drivers (usbserial.o)
in the 2.4 series kernels or backported versions.
The interface is a checksummed, packetised protocol. Commands from the master (PC) are interleaved by responses from the
reader. A specification of the interface protocol for the serial and USB RFID interrogators is available on request. Ordering Information
