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
Method
Description
DHCP
A DHCP server automatically assigns the IP address and network
settings. See
XPort™
Installer
You manually assign the IP address using a PC attached to the network.
See
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
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
Serial Port
Login
You initially configure the unit through a serial connection.
