Figure 27 Configuration interface for GPIO
⚫ GPIO x: define the functions of the four GPIOs, it need to be powered on again to
take effect;
① Disabled: don't use this GPIO；
② As input x: After the setting takes effect, you can use the get Input Status
command to read the current level status of the GPIO;
③ As output x: After the setting takes effect, you can use the output control
command to make the GPIO output high or low levels;
⚫ Output port initial status: it needs to be powered on again to take effect.
Output x: the default setting is low level. After the device is powered on, the
default state of the output port is low level.
6.1.4. RF And Air Protocol
Figure 28 Configuration interface for RF and air protocol
⚫ RF parameter:
Transmitter power: 1W~8W, the default setting is 4W.
Receive sensitivity: the default setting is high.
When RF closed, Keep antenna port open: check to take effect.
Enable EMC: check to enable EMC mode.
⚫ Air protocol:
CMD ASK: set whether the communication frame of ISO15693 protocol adopts
100% or 10% modulation;
EOF ASK: when using 16 slot counts, whether the EOF of the switching time slot
