Industrial RS232 to RS485 Converter

This port-powered adapter translates RS232 signals to RS485 for industrial long-haul communication. It supports bi-directional data flow over distances up to 4000ft or 1.2km. The unit draws power directly from the serial port, removing the need for an external supply. It suits engineers integrating legacy equipment into multi-drop networks.

32-node multi-drop capacity

The converter enables up to 32 devices to share a single RS485 bus using two-wire half-duplex wiring. Automatic RX-TX control manages transmit and receive switching without software intervention. Baud rates up to 115.2 kbps are auto-detected for point-to-point or point-to-multi-point links. This node limit is the key constraint for network planning.

Simple installation with surge protection

Connection uses standard DB9 and terminal block interfaces for quick wiring. A built-in TVS diode provides 600W anti-surge and 15KV static protection to guard attached hardware. Common issues include incorrect polarity on the RS485 pair or missing ground reference between nodes. Ensure termination resistors are fitted only at the bus ends.
