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:
• IP address
