10Base-T Network
The Galaxy Gateway has an IEEE 802.3 compliant 10Base-T
network interface. Since the cable length required to connect the
Galaxy Gateway to the network is variable, this cable must be
supplied by the user. Connect the network interface cable from
the IEEE 802.3 compatible network to J1 (RJ-45) connector on
the Galaxy Gateway as shown in Figure A-3.
1. Connect one end of the network interface cable to J1 (RJ-45
Network Interface Connector), usually located at the bottom
right on the Galaxy Gateway. (Other configurations are
possible with the hardware shown in Figure A-3.)
2. Connect the other end to an IEEE 802.3 compatible
network.
Configuring
Network
Communications
The Galaxy Gateway uses Transmission Control Protocol/
Internet Protocol (TCP/IP) to communicate with the host
computer on a local area network. TCP/IP is a widely used
protocol that provides communication across networks of
diverse computers and devices. This protocol forms the basis for
the Internet. Each device or host on a
TCP/IP network has its own IP address. The IP address is a 32-
bit number, usually written in dot notation (e.g., 127.9.235.48).
Another 32-bit number, called subnet mask (or address mask,
netmask, e.g., 255.255.0.0) is used to identify the network
portion and subnet portion of the IP address.
1. Connect a PC to the local port (9-pin female connector) of
the Galaxy Gateway.
2. Using the built-in configuration utility, enter network
configuration information. This information may have to be
provided by the network administrator. The following
equipment is required:
• PC with terminal emulation program
• Serial interface cable (DB-9 Male) for connection to the
Galaxy Gateway
To configure the Galaxy Gateway for your network, the
following information is required for the Galaxy Gateway
and your network:
