Figure 3-1 - Evaluation Board Connected to Serial Device and Network
1. Connect a serial device to your unit.
2. Connect an Ethernet cable to the XPort™ Ethernet port.
3. Supply power to your unit using the power supply that was included in the packaging.
Note: The required input voltage for the XPort™ Evaluation Board is 5VDC (3 W
maximum).
4. Supply power to the serial device.
3.3 Methods of Assigning the IP Address
The unit's IP address must be configured before a network connection is available. You
have several options for assigning an IP to your unit, however, we recommend XPort™
Installer on page 3-5.
Method Description
DHCP A DHCP server automatically assigns the IP address and network
settings. See
DHCP on page 3-3.
XPort™
Installer
You manually assign the IP address using a PC attached to the network.
See
XPort™ Installer on page 3-5.
ARP and Telnet You manually assign the IP address and other network settings at a
command prompt using a UNIX or Windows-based system. Only one
person at a time can be logged into the configuration port (port 9999).
This eliminates the possibility of several people simultaneously
attempting to configure the unit. See ARP and Telnet on page 3-9.
AutoIP This automatic method is appropriate when you have a small group of
hosts rather than a large network. This method allows the hosts to
negotiate with each other and assign addresses, in effect creating a small
network. See AutoIP on page 3-4.
Serial Port
Login
You initially configure the unit through a serial connection.
See Serial Port Login on page 3-9.
