Cygnus 2 Operating Manual
9.2.2 TCP/IP Ethernet Port
The optional TCP/IP interface supports only the Standard Ethernet TCP/IP
protocol. Cygnus 2 will communicate via TCP/IP on TCP port number 2101. The
interface supports static addressing, DHCP is not supported. Ethernet parameters
allowed to be set are the IP address and the net mask.
9.2.2.1 Network Connection
If Cygnus 2 is connected through a network or hub connection, a standard
"straight" Ethernet cable is required.
9.2.2.2 How to Set Up the Network Protocol on the PC
Most personal computers (PC) are configured to obtain the IP address, an address
which defines the computer on the Internet, automatically from a server.
To communicate directly with Cygnus 2, the Internet protocol (IP) on the PC must
be configured manually and an Ethernet crossover cable (for example, IPN
600-1211-P5) must be connected between the PC and Cygnus 2. Some PC’s will
auto-configure and work with either straight or crossover cable. Instructions are
provided here for manually configuring the Internet protocol.
NOTE: If the PC only has one Ethernet port (that is, one network connection) then
setting the PC for direct communications will prohibit it from accessing the
Internet until that setting is reversed.
NOTE: These instructions will set two values, the IP address and the Subnet
mask, which will most likely prohibit access to the Internet. If these values
already contain information then this information should be recorded
somewhere for use in restoring the Internet connection.
To access the Network Connection on the PC, select Network Connections from
the Windows
®
Start menu or from the Control Panel. See Figure 9-1.
