RS485 433MHz 20dBm Wireless Transceiver

Dual-unit set of ruggedised 433 MHz VHF/UHF radio modems for RS485 networks. Each unit measures 74 × 24 × 16 mm (excluding antenna), housed in durable plastic + metal casing. Operates on 4.5–5.5 V DC supply, interfaces via standard RS485 pins (5V, GND, A+, B−). Frequency band: 433–458.5 MHz (255 channels); output power: −40 to +20 dBm (100 mW max); receiver sensitivity: −114 dBm. Transparent serial mode supports 1200–19200 bps (default 9600); over-the-air data rate: 10–100 kbps. Features built-in MCU for serial parameter setup; AT commands (e.g., AT+ENABLE=1) accepted only within first 3 minutes after power-up. Supports ID-configurable topologies: point-to-point or star (one master, multiple slaves), emulating wired RS485 bus behaviour — master sends to all, any node may reply (with strict single-transmit arbitration). Certified for continuous operation from −25 °C to +75 °C. Proven in IP PTZ camera links, Modbus temperature sensors, LED controllers, RS485 relay modules (R4D3C32/N4D8B08/N4D8C12), remote metering, Wiser Home ecosystems, and access control infrastructure.
