RS485 might sound like a protocol from the last millennium, but by utilising the latest devices from companies like Maxim, you can achieve long range, reliable and fast networks for pennies.

Recently we completed a project that distributed 32 channels of control and audio data over a 2-wire network. Over these same two wires we were distributing power! To make matters worse, the cable was 30 year old legacy cable. This was only made possible by harnessing the simplicity of RS485 combined with the sophistication of the latest RS485 silicon.

RS232 is becoming rarer these days. We would ask you to carefully consider your reasons for choosing RS232; we find users tend to prefer USB.
