Operation Notes About The Ports - Vivanco NBK DOCK U2 14378 Manual

USB 2.0 DOCKING STATION
Self-Power Mode vs Bus-Power Mode
Note that there are two modes of powering USB peripherals, self-power mode and bus-power mode. The
self-power mode means the peripheral has its own power adapter for operation. Bus-power mode means the
peripheral operates under the power from the upstream port that it is connected to.
The USB 2.0 docking station can operate under both USB bus-power and self-power mode. However, under
bus-power mode, the individual downstream facing ports of the docking station cannot supply current for more
than 100mA. Therefore, devices (e.g. USB scanner or multi-function peripheral, MFP) with power requirements
higher than this value will not work. In this situation, it is recommended to operate the docking station in the
self-power mode whenever possible. USB bus-power mode is only for devices with low power consumption .

3. Operation Notes About the Ports

When connecting peripheral devices to the docking station, pay attention to the following notes:
USB Hub Ports:
When connecting a USB device to one of the downstream USB ports of the docking station, make sure to
follow the software installation manual accompanied (if any) with this USB device.
PS/2 Ports (Keyboard and mouse port):
Some compatibility issue may occur due to the loosely specified PS/2 protocols and the sheer number of
existing brands/models. However, if the PS/2 keyboard or mouse is IBM PC compatible, then it should be
able to work with the docking station properly.
Serial Port:
Note that serial port is not a plug and play interface. If you connect a serial port device (e.g. a modem) to the
docking station and the docking station is already connected to a PC, you need to perform the Add New
Hardware function from the Control Panel or remove and re-plug the docking station to the PC to find the
device and perform the function.
USB-to-serial interface:
The interface was designed to work with modems or any serial device that has drivers capable of handling
"VIRTUAL PORT". Serial mice are old devices, and most of their drivers recognize physical serial ports only.
Thus, the compatibility of the USB-to-serial interface and the serial mouse is not guaranteed at all. There are
a few rare cases where it can work, but the majority of the serial mice is not compatible with the USB-to-
serial interface.
LAN Port:
This port supports Ethernet 10/100 Mbps function.
