RS232 suits short distances (under 15 metres) and single-device connections. RS485 and RS422 support longer distances (up to 1200 metres), and RS485 also supports multiple devices on the same line. If you need longer cable runs or multiple connected devices, RS485 is usually the better choice.

A signal isolator breaks the direct electrical connection between two devices while still passing the data through — protecting equipment from ground loops, voltage surges and electrical noise when devices are earthed at different points. Use one whenever connected equipment sits on separate power systems, in electrically noisy industrial environments, or wherever a fault on one side must not damage the other. Our Isolators range covers serial, USB, network and analog signal interfaces.
