INTRODUCTION:
MOD-RFID1356
is an RFID station, able to interact with ISO15693
compliant VICC transponders. All the complexity of RFID tag detection,
verification and decoding are handled by MOD-RFID1356. Custom
command requests can be initiated to facilitate VICC EEPROM read and
write operations.
MOD-RFID1356 supports two distinctive modes of operation, easily
switched by a single button press. It can emulate USB HID keyboard and
input the read TAG ID directly to any Windows application, including the
venerable Notepad. Or it can emulate USB CDC serial port for easy access
from custom user applications using standard code for COM port access.

Supports ISO15693 compliant VICC transponders like EM4034.
Base RFID frequency 13,56MHz;
USB port connection to PC;
Two modes of operation, easily changed by pressing the button;
USB HID keyboard emulation mode;
USB CDC serial port emulation mode;
Simple command-line interface in USB CDC mode for configuration,
data acquisition and initiation of custom command requests;
Two LEDs indicating device status and tag presence;
Support for continuous and periodic RF scanning to better suit user
power requirements;
Ships with default mode USB HID and default configuration:
continuous read, scan always, LEDs activated;
ELECTROSTATIC WARNING:
The MOD-RFID1356 board is shipped in protective anti-static packaging.
The board must not be subject to high electrostatic potentials. General
practice for working with static sensitive devices should be applied when
working with this board.
REQUIREMENTS:
Cables:
1.8 meter USB A-B cable.
Software:
Software needed for USB HID keyboard mode:
- Notepad or other text editor.
Software needed for USB CDC mode:
- HyperTerminal or other terminal program.
SUPPORTED RFID TAGS/VICC:
MOD-RFID1356 supports RFID transponder tags with the following
characteristics:
- ISO15693 compliant transponders;
- 13,56MHz carrier frequency;
-
1 out of 4
transmission encoding (VCD to VICC);
- High data rate (26,48kbit/s) reception encoding using one sub-
carrier frequency.
CAVEAT:
MOD-RFID1356 does not support reliably the anticollision
algorithm as defined in the ISO15693 standard. It
will
work reliably only if
there is a single VICC in the vicinity
or
if there is no RF collision. If there is
an RF collision, supposedly because of two VICCs with almost identical
UIDs, it might not detect both of them.
POWER SUPPLY:
Normally the device is supplied from USB.
LEDS:
In normal mode the GREEN LED is on whenever the RF antenna circuit is
active and scanning for RFID tags. The RED LED switches on whenever a
valid RF TAG ID is being scanned and decoded successfully.
The LEDs can be switched off to save power consumption. See the
“Command Line Interface” section for more information.
In boot loader mode the LEDs have other meaning. See the “Firmware
Upgrade” section for more information.
PC DRIVER INSTALLATION:
Drivers for the USB HID mode are integrated in Windows XP/Vista.
The driver for USB CDC mode is available from our website. Windows
installation steps are the following:
1. Download and unzip the file “MOD-RFID1356-drivers.zip” in a
temporary directory.
2. Plug the programmer in the USB port.
3. Point the Device Wizard to the temporary directory.
4. Windows will complain that drivers are not signed. Click “Continue”.
5. Click finish.
Screen shots of the steps are shown below:
Linux distributions normally include drivers both for USB HID and USB
CDC classes. Depending on which driver is loaded in the kernel, user
should look either for
/dev/ttyACMn
or
/dev/ttyUSBn
where "n" is a number, assigned by the kernel to the plugged device.
USB HID MODE:
When device is connected via USB to a host PC it will represent itself as
USB HID keyboard. When an RFID transponder is detected in the vicinity,
the module will type the HEX-representation of the transponder ID.
To use

3.
the device in this mode:
Open Notepad.
Plug in the device in the USB port of the PC.
Put an RFID tag in front of the device. The TAG ID will be entered in
the currently opened text file.
There is no need for OS driver because all major operating systems include
USB HID drivers.
NOTE:
This mode does not allow configuration of device parameters. MOD-
RFID1356 is shipped with default configuration for continuous read. If this
