4.2.3.1 Web Access and Update from Computer through the Mini USB
The Mini USB port on the front panel of the unit can be used as a virtual IP
connector through an USB-to-Ethernet adaptor. A computer connected through an
USB-to-Ethernet adaptor to the front panel USB connector can provide the same
functions as a computer connected to the control Ethernet interface of the unit. In
this way the USB port can be used for unit upgrade and control. To access the unit
from a computer through the USB connector, proceed as follows:
1. Connect an USB-to-Ethernet adaptor to the front panel USB connector with a
USB cable.
2. Connect one of the Ethernet ports of the control computer to the Ethernet port
on the USB-to-Ethernet adaptor through an UTP cable.
3. Set up the Ethernet interface of the control computer connected to the USB-to-
Ethernet adaptor as detailed in Table 4.1.
Table 4.1 Ethernet Interface Settings
Parameter Setting
IP Address 192.168.20.[2-255]
Gateway Address 192.168.20.1
Subnet Mask 255.255.255.0
Note: The USB interface uses the IP address 192.168.20.20, so this address
cannot be assigned to the control computer.
4.2.3.2 Configuration Handling through USB
Configurations can be loaded or imported from, and saved or exported to a USB
stick connected to the front panel USB connector.
Note: The USB stick must be pre-formatted to FAT32 file system prior to use. The
Unit Config/USB Control/Format USB Stick command on the front panel
does not actually format the attached USB stick; it only clears its content
and recreates the directory structure required by the unit.
