must be changed then device must be switched to USB CDC mode and
configured using the serial command line interface.
USB CDC MODE:
In this mode the device represents itself as USB CDC virtual serial port. It
provides a simple shell-like command line interface for configuring and
interacting with the module. The device echoes back the typed characters
and waits for Carriage Return (Enter) before processing the line input. See
“Command Line Interface” for more information on the supported
commands.
Any terminal software can be used to open the COM port, assigned by the
OS, and type in commands.
SWITCHING OPERATING MODES:
The current mode of operation can be selected by pressing and holding the
button of the device. After two seconds the LEDs will start to blink and will
show the code for the next selected mode. When button is released, the
device will reboot and enter the selected mode. Selected mode is
remembered between power downs. The assigned codes are:

COMMAND LINE INTERFACE (USB CDC mode):
The command line interface, available in USB CDC mode, allows device
configuration and reading of successfully decoded TAG IDs. Just open the
serial port assigned to MOD-RFID1356 using HyperTerminal or similar
terminal program, and start typing commands.
For the impatient: type '?' and press enter to see a short help for the
supported commands. Any typed character will be echoed back; 'enter' will
force the module to process the input command line.
