System Description

SYSTEM DESCRIPTION

The NFC module is a specific RF module used in VIO Series professional audio equipment of dBTechnologies brand.

Is not allowed and expected use of this module in a different application than the VIO Series final products.

The NFC data exchange system consists of a Master device (NFCMaster1) and a Slave device (NFCSlave1); they are

able to communicate by exchanging data when they are physically located nearby (distance less than about 10cm).

The Master device is the only one able to initiate a communication; the Slave device is instead only passive.

Both devices are controlled by a host device that, in addition to supplying power, reads and writes data to a digital

communication channel.

Dimensions (WxLxH) 72x42x15mm

Mounting With screw

Host comuncation UART, 8N1, 9600baud, 3.3V

Power supply 3.3V DC ± 10%, < 100mA

Max Radiated ERP power -35dBm

Operating frequency 13.56MHz

Operating temperature -20 – +50°C

The master NFC device is connected to the host device via a multipolar cable; power and communication lines (UART) transit on the same cable. The NFC Slave device has two identical connectors. In connector A, the host device is typically connected via a dedicated multipolar cable that simultaneously carries power and data (I2C). A further additional I2C module can be connected to the B connector in cascade. 1 – Vcc 3.
