INTRODUCTION
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.
All of the RS-232 ports function as native Windows COM ports, and are all compatible
with Windows serial communication applications. Each of the eight serial ports is
individually configurable with different serial communication parameters (speed, data
bits, stop bits, parity and RTS/CTS, XON/XOFF flow control, transmit and receive FIFO
size…etc.).
HubCOM-880i-RM USB combo hub is designed for use in industrial applications. It is
housed in a DIN rail mountable metal case with screw holes for securing USB and
power cables. Next to each USB downstream port connector, there are two screw
holes for securing USB cables to ensure reliability of connection. The terminal power
input connector is securely locked with two screw holes, preventing the power wires
from accidentally disconnecting. This combo hub is able to operate at a wide ambient
temperature range from -40°C to 70°C (-40°F to 158°F), allowing it to be used in harsh
environments.
The USB combo hub expands the number of USB ports and adds several RS-232 ports.
When you need a USB to RS-232 interface while increasing the number of ports, the
HubCOM-880i-RM is an ideal combo hub to use.
