sent, then only link 1 will send this piece of information. For the specific rules of the header, see the protocol
transmission part that follows.
Baud Rate/Data/Parity/Stop Bits It represents the properties of the 485 serial port of the device. If it is changed,
after restarting the device, the host computer must change the topmost serial port property to the content you
changed, and then open the serial port to conduct normal communication.
Packing time/packet length The default value is 50/1024, which means that 50ms is the minimum interval
between two packets of data. For example, if the time interval between sending two packets of data to 485 is very
small, only 30ms (less than 50ms), then the two packets of data will be combined into one packet of data. It will be
distinguished. The packet length of 1024 means that if a packet of data is very long, up to 1300 bytes (greater than
1024), it will be divided into two packets of data to send.
Serial Heartbeat Packet/Serial Heartbeat Packet Time/Serial Heartbeat Packet Content This function is
disabled by default. Users need to open it by themselves (check the serial port heartbeat package option), the serial
port heartbeat package time unit is seconds, the heartbeat content is the content that will be sent through 485, and
the hex check on the right means that The heartbeat content will be converted into hex format (hex format is rarely
used, if checked, the content in hex format will be sent). After opening, the device will send serial heartbeat
information through 485 every other serial heartbeat time.
Basic information area ------ WiFi parameter area (configured to take effect after restarting)
WIFI Mode/SSID/Password Parameters representing wifi, such as AP mode, ssid is test, password is
12345678(When entering a password, you can enter a lowercase "x" to set it as open WiFi), then the device is a
hotspot, which can be connected through wifi, the hotspot name is test, and the password is 12345678. If the STA
mode is set, the ssid is test, and the password is 9876543210, then the device will use the password of 9876543210
to connect to a router (hotspot) named test after restarting.
DHCP/Static IP/Subnet Mask/Routed Address The DHCP selection part can choose dynamic IP and static IP
mode (it works in STA mode). If it is dynamic IP, it is easy to understand, that is, after the device is connected to
the router (hotspot), the IP of the device is dynamically assigned to the device by the router (hotspot). Yes, so every
time you restart the device or reconnect to wifi, the address of the device may change. If it is static IP mode, you
can fill in the IP address you want to fix in the static IP below, but note that this cannot be filled in randomly, it
must be kept on the same network segment and this address is not assigned to other devices, for example, your
router is 192.168 .3.XXX network segment, your static IP can only be filled in such as 192.168.3.52. It cannot be
filled in across network segments. Generally, the following subnet masks do not need to be changed. The routing
address is the IP address of the router. In the correct case, every time the device is powered on and connected to the
