Low-cost Wi-Fi serial server RS232/485 USR-W600 Cost-effective Added featured firmware: SSL/HTTPS/MQTT/MQTTS/ONENET Upgrade iteration Hardware guard design such as hardware watchdog, 24 hours without downtime, stable operation Wide temperature and pressure Industrial design for a wide range of application site temperature and voltage requirements Electrostatic protection ESD Prevent static damage to equipment Such as: dust electrostatic, electric environment arc, etc. Air ±15KV Contact ±8KV Operating mode Transparent transmission mode In this mode, all data that needs to be sent and received is not parsed between the serial port and the wifi interface. Minimize the complexity of user usage. AT command mode In this mode, the user can perform ∪ART and network participation setting for the WIFI module through the AT command. HTTPD Client mode The data is directly transmitted to the HTTP server, or the data serial port data is obtained from the HTTP server. The best choice for submitting a web server to the B/S architecture system by Http (GET/POST) Heartbeat packet mechanism The network heartbeat packet informs the server that it is active and maintains a normal connection with the server by continuously sending heartbeat packets. The serial port heartbeat packet informs the serial device that it is in an active state, and actively captures sensor data that cannot be actively pushed. Registration package mechanism When the server functions as the TCP Clienti and UDP Client, it automatically sends a predetermined registration packet to identify it after establishing a link. The registration packet data can be a MAC address or a custom registration data. Airkiss intelligent distribution network WeChat distribution network printer air purifier air conditioning Smoke detector Fast networking protocol LAN search WIFl connection exception handling Internet function Module as AP mode Mobile devices such as computers or mobile phones that do not need any configuration can quickly access the WIFI module for data transmission, and the maximum number of accesses is 3 Module as STA mode Access to routers for remote communication or device communication within the LAN Module as AP+STA mode It can realize local area network LAN communication, and support remote equipment wide area network communication, and access up to 3 STA devices. Realize real-time transmission of control center data Support RS485 communication to improve anti-dry resistance and isolation Ultra-high cost performance, large-scale application reduces overall project cost
