Two-Port USB to RS232 Adapter

The Koss ICUSB2322I adds two DIN rail-mountable RS232 serial ports to any system through a single USB connection. It is designed for industrial environments where legacy serial equipment must interface with modern computers. Wall-mountable hardware and DIN rail clips provide secure installation in cabinets or on machinery frames. This adapter suits engineers and technicians maintaining PLCs, HMIs, or older industrial controllers.

Sustained Industrial Operation

The industrial-grade construction supports continuous operation in demanding environments without the overheating risks seen in consumer-grade converters. Each port maintains stable RS232 signalling over long cable runs typical in factory settings. The DIN rail mounting prevents vibration-induced disconnects that can interrupt critical processes. Buyers needing more than two simultaneous serial connections or non-RS232 protocols will require additional adapters.

Questions about this item

Does the ICUSB2322I generate noticeable heat or fan noise when both serial ports run continuously?

The adapter has no fan and draws power from the USB bus, so it runs silently and stays cool even with both RS232 ports active all day.

What cables or connectors must I already have to attach my RS232 equipment to the ICUSB2322I?

You need two standard DB9 serial cables; the adapter provides two male DB9 ports ready for direct connection.
