4. NFC
The NFC interface of the RYMASKON 200 device can be used to get additional information and configuration
options for room automation. The RYMASKON 200 will behave like an NFC tag that can be read by an NFC
enabled device. The antenna is located behind the LCD and best performance is achieved by putting the NFC
enabled device right on the front panel glass. Depending on where the antenna of the mobile device is located the
optimal position will be found by moving the device slowly over the front panel. Best performance can be
achieved by positioning the device in a more or less horizontal position covering the LCD as shown in Figure 8.
Figure 8: NFC Device Positioning
If the connection is established the NFC field detection bit at the short_pressed Modbus register at address 1
(Table 7 on Page 19) will be set. In the meantime the NFC enabled device will read the memory of the tag and will
perform an appropriate action.
Since a NDEF URI record is saved at the tags memory the device will ask to open the defined URL in the browser
of the NFC enabled device.
