Rack-Mountable – Wide Temp Range – Industrial 8-Port USB to RS-232 Serial Hub

The HubCOM-880i-RM is a rugged, industrial-grade Rack Mountable USB 16-Port combo hub consisting of 8 USB to RS-232 serial ports and 8 ports industrial USB 2.0 hub. This USB serial combo hub is compliant with USB 2.0 specification, it expands one USB host port into a combination of 8 high-speed RS-232 serial ports and 8 highly-efficient USB 2.0 ports.

This industrial-grade HubCOM supports USB 2.0 high speed of 480 Mbps, USB 1.1 full speed of 12 Mbps, and low speed of 1.5 Mbps. It is powered by a quality industrial-grade switching power supply.

Wide Temperature USB 2.0 to 8 Port Serial Hub

The HubCOM-880i-RM USB Hub is designed to make RS-232 serial port expansion fast and uncomplicated, in addition to adding 8 USB 2.0 downstream ports for easy USB ports expansion. The HubCOM-880i-RM is automatically detected and installed to the system once connected, no additional memory resources are used on the system.

USB 2.0 Port Support

  • 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 ~ 480Mbps), automatic link and speed detection
  • All USB connectors with screw holes to lock the USB cable for extended security

Compatible with Windows Communication Applications

All RS-232 ports function as native Windows COM ports, and they are all compatible with Windows serial communication applications. Each of the 8 serial ports is individually configurable
with different serial port speeds, serial communication parameters of data bits, stop bits,
parity and RTS/CTS, XON/XOFF flow control, transmit and receive FIFO size, etc.

The HubCOM-880i-RM Rack Mountable USB Serial Hub is designed for the use in industrial application under
tough working environments. It is housed in a DIN-rail as well as rack-mountable metal
case with screw holes on each USB port for lockable USB and power cables. Next to each USB downstream port connector are two screw holes for lockable USB cables to add extra reliability of connection. The terminal power input connector has two screw holes securely locking the power wires to prevent them from accidental disconnection.

Screw-Lock USB ports for secure connection

The USB to Serial Hub Combo incorporates the USB hub chips specifically for industrial usage. Each downstream port provides full 500mA power to the connected USB devices. This HubCOM is featured with normal operation in wide ambient temperature from -40°C to 70°C (-40°F to 158°F) operation in a harsh environment. All the USB data lines and RS-232 signals are protected by 15KV ESD protection.

HUBCOM-880i-RM Features

  • 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
