CMG-DCM
control attached digitizers using its own interface.
4.4 Network configuration
These settings must be provided if you intend to connect a DCM to a TCP/IP
network, whether over a serial link via PPP, or using Ethernet or wireless
connections.
Ethernet port
The settings described below begin net.eth.0 because they refer to the first
Ethernet interface. If the optional 802.11b (“Wi-Fi”) hardware is installed, the
settings on this page will begin net.wlan.0 and refer to the wireless LAN rather
than to Ethernet networking. They are otherwise identical.
net.eth.0 : If you know the IP address the DCM is going to use over this
interface, you should set this option to static and fill in the details below.
Alternatively, you can select dhcp/bootp and have the DCM automatically
request an address over the network. If you choose the dhcp/bootp option, you
should ensure that a gateway computer exists on your network that can receive
these requests, and that the DNS (nameserver) entry for the DCM is kept
current. You can then ignore the remaining settings on this page.
net.eth.0.address : If the above option is set to static, you should fill in the IP
address of the interface in this box. Valid IP addresses consist of four numbers
between 0 and 255, separated by periods. If you intend to attach the DCM to a
private network, you should use an IP address in one of the private ranges
(10.b.c.d; 172.16-31.c.d; 192.168.c.d) to avoid clashing with addresses on the
wider Internet.
