PW41-M: Protoss PW41-M RS485 to WiFi&BLE, 9-50VDC Input, 10W

PW4X provides a protocol conversion product between RS485/RS232 serial ports and TCP/IP, offering a solution for serial devices to transmit data via WIFI/BLE. This product boasts a rich communication protocol, supporting TCP, UDP, MQTT, HTTP, virtual serial ports, and other methods for upstream communication. For downstream serial devices, it supports transparent data transmission, Modbus TCP and Modbus RTU conversion, scheduled data collection, and data format conversion. With various configuration options, the product can be applied in a wide range of scenarios. PW4X uses a highly integrated hardware and software platform. The product supports 802.11b/g/n wireless standards, a complete TCP/IP protocol stack, and multiple data encryption methods to ensure data confidentiality. It has numerous established use cases in industrial automation, energy and power, rail transport and public facilities, building automation, and more.

**PW41 Model**: RS485 has output cables A(data+) and B(data-) respectively. When connecting with RS485, connect A+ to A+ and B- to B-. In case of severe interference, it is recommended to connect the GNDs together. Up to 32 485 terminal devices can be connected via the bus. The maximum communication distance is 1200 meters. The 485 terminal resistance is 120 ohms, generally required for wiring over 300 meters.
