The ARS485 converter takes advantage of RS485 on systems original equipped with RS232. It transparently converts RS232 signals into RS485 signals. The ARS485 lets you build an industrial grade, long distance communication system with standrd PC hardware.
Circuitry in the ARS485 automatically senses the direction of data flow, dispensing with handshaking requirements in the network, and reducing the cabling requirements in an RS485 network to just two wires. Data transmission speeds of up to 115.2 Kbps are possible.
