Keysight E5805A USB/4埠RS232介面，可讓您從筆記型電腦或桌上型電腦的USB埠直接連接最多4台RS232儀器或設備。您不必設定切換器或安裝PC卡，也不需要使用外部電源供應器。只要安裝好軟體，並插入E5805A USB/4埠RS232介面，為您的電腦增加4個RS232埠。連接工作從來沒有像現在這樣容易。
連同軟體一起出貨的E5805A，讓4個RS232埠看起來就像您電腦上多出來的本機（Windows COM）埠一樣。另外，隨附的工業標準VISA IO Libraries則提供儀器指令來控制RS232。
由於E5805A是一個標準的隨插即用裝置，因此會在連接到電腦的USB埠時進行偵測與設定。您最多可以連接4台設備，每個RS232埠可提供最高230Kbps的傳輸速率。E5805A提供4個DB-9序列接頭，並附了一條1公尺長的USB接線讓您將E5805A連接到電腦。
