Reliable serial communication
Choose serial converters, repeaters and isolators by interface, port count, baud rate, isolation, connector, DIN format, drivers and cable length
DistriNode serial converters, repeaters and isolators connect legacy devices, PLCs, meters, POS terminals, access control, CNC machines, routers, servers and industrial controllers wherever RS-232, RS-422, RS-485, USB or Ethernet must run reliably. Compare USB serial adapters, multiport converters, long-distance repeaters, optically isolated interfaces, surge protection, screw terminals, DB9, DIN enclosures, Windows and Linux drivers, Modbus, half-duplex and full-duplex.

How to choose serial converters
Match the standard
RS-232, RS-422 and RS-485 use different wiring and signals.
Check isolation
Optical isolation protects against ground loops and industrial interference.
Plan for drivers
Service laptops and servers may need specific chipset support.
Mind the distance
Repeaters and termination stabilise long RS-485 runs.

Integration tip: Before replacing a device, note down its standard, connector, baud rate and wiring mode.
Frequently asked questions
Can RS-232 and RS-485 be connected directly?
No, you need a suitable converter for that.
When do you need isolation?
With different power supplies or electrical interference.
Why do some USB serial adapters not work with legacy devices?
Drivers, signal levels or handshake lines may differ.
