Getting Started
3. Getting Started
This chapter covers the required steps to get the XPort™ device server on-line and working.
There are two basic methods used to log into the Device Server and setup the IP address:
!
Network Port Login: Make a Telnet connection to the network port (9999).
!
Serial Port Login: Connect a terminal or a PC running a terminal emulation program
to the Device Server’s first serial port (CH 1).
It is important to consider the following points before logging into and configuring the
XPort™:
!
The XPort™ IP address must be configured before a network connection is
available.
!
Only one person at a time may be logged into the network port. This eliminates the
possibility of several people simultaneously attempting to configure the Device
Server.
!
Network port logins can be disabled. The system manager will not be able to access
the unit. This port can also be password protected.
3.1 Addresses and Port Number
The Ethernet address is also referred to as the hardware address or the MAC address. The
first three bytes of the Ethernet Address are fixed and read 00-20-4A, identifying the unit as
a Lantronix product. The fourth, fifth, and sixth bytes are unique numbers assigned to each
unit.
00-20-4A-14-01-18 or 00:20:4A:14:01:18
Every device connected to an IP network must have a unique IP address. This address is
used to reference the specific unit.
Every TCP connection and every UDP datagram is defined by a destination IP address and
a port number. For example, a Telnet application commonly uses port number 23. A port
number is similar to an extension on a PBX system.
The unit 's serial channel (port) can be associated with a specific TCP/UDP port number.
Port number 9999 is reserved for access to the unit's Setup (configuration) Mode window.
