Send Enquiry


TITAN’s HubCOM-880i-RM is a robust, industrial-grade rack-mountable 16-port USB combo hub. HubCOM-880i-RM expands one USB port into eight USB to RS-232 serial ports and eight USB ports. All USB data lines and RS-232 signals are protected by 15kV ESD protection.

The HubCOM-880i-RM supports USB2.0 high speed 480Mbps, USB1.1 full speed 12Mbps or USB1.1 low speed 1.5Mbps data transfer rates. It is powered by a high quality industrial-grade switching power supply and provides up to 500mA current to downstream devices. There is no need for any driver or software installation. By plugging the cable from the USB combo hub to the host USB port of the PC and connecting your USB devices to the downstream port of the combo hub, the host PC immediately gains eight USB to RS-232 serial ports and eight USB ports. There are no IRQ & COM port conflicts, since the port doesn’t require any additional IRQ, DMA, memory as resources on the system.


  • Adds eight industrial RS-232 serial ports and eight USB2.0 ports by connecting to a USB2.0 or USB3.0 port
  • 15kV ESD immunity for all USB data lines and all RS-232 signals for protection
  • Provides a terminal block connector to supply 5V 3A power for external devices
  • LEDs for power, USB status of each hub port, TxD and RxD of each serial port for easy monitoring of port activity and status
  • 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 921.6kbps
    • 2kb transmit FIFO & 2kb receive FIFO
  • USB 2.0 port:
    • Each port provides 5V 500mA power to downstream device
    • Supports USB1.1 and USB2.0 transfer speeds (1.5 to 480Mbps) with automatic link and speed detection
    • Overcurrent protection
    • All USB connectors have screw holes to secure USB cables
