Section 3 – Net-2000™ VCU Control
DVSI Confidential Proprietary
Note:
The Ethernet MAC address and default hostname of the VCU is derived from the serial
number of the VCU. The MAC address will begin with 00:01:FD followed by the last six
digits of the serial number. The hostname is NET2K followed by the last four digits of the
serial number. For example, if the last six digits of the serial number are 301234, the
MAC address is 00:01:FD:30:12:34 and the hostname is NET2K1234.
When no DHCP server is available on a LAN the VCU’s RS-232 serial port can be used as a console
terminal for low-level network setup. With the serial cable connected and the terminal running type a
few carriage returns from the PC’s keyboard. The Net-2000™ VCU will respond with the console
prompt as shown below:
adsh>
At the adsh prompt the VCU’s network settings can be configured or changed using the terminal
console command “network” as follows:
adsh>network [-dhcp] [-h hostname] [-w workgroup] [-i ipaddress] [-m
netmask] [-g gateway] [-n nameserver][-d domainname]
The arguments to the network command are described below:
