HubCOM-880i-RM - Rack-Mountable USB to Octal RS-232 Serial & Industrial 8-Port USB 2.0 Hub

The TITAN HubCOM-880i-RM is a rugged, industrial-grade rack-mountable USB 16-Port combo hub consisting of 8 USB to RS-232 serial ports plus 8 ports industrial USB 2.0 hub. This industrial USB 16-port HubCOM provides 8 USB 2.0 downstream ports and 8 USB to RS-232 serial ports. This USB serial combo hub is compliant with USB 2.0 specification, and it expands one USB host port into 8 high-speed RS-232 serial ports and 8 high-efficient USB 2.0 ports by connecting to a USB host port.


  • Adds eight industrial RS-232 serial ports and eight USB 2.0 ports by connecting to a USB 2.0 or USB 3.0 port

  • Industrial-grade USB 2.0 hub with rack-mountable SECC metal case

  • Suitable for DIN-rail and rack mounting. DIN-rail ears and rack brackets provided

  • Industrial RS-232 serial port supports:

    • Full RS-232 modem control signals (TxD, RxD, RTS, CTS, DSR, DTR, DCD) and hardware/software flow control
    • Baud rate up to 921.6 Kbps
    • 2K bytes transmit FIFO & 2K bytes receive FIFO
  • USB 2.0 port supports:

    • Over-current detection and protection circuit design for USB hub
    • Each downstream USB port supplies 5V 500mA power for external high-power USB devices
    • Supports USB 1.1 and USB 2.0 transfer speeds (1.5 ~ 480 Mbps), automatic link and speed detection
    • All USB connectors with screw holes to lock the USB cable for extended security
  • Provides a terminal block connector to supply 5V 3A power for external devices

  • 15KV ESD immunity for all USB data lines and all RS-232 signals for protection

  • LEDs for power, USB status of each hub port, TxD and RxD of each serial port for easy monitoring of port activity and status

  • Supports wide ambient temperature operation -40°C to 70°C (-40°F to 158°F)

  • CE, FCC approval
