3: Installation of the XPress DR Device Server
XPress™ DR Industrial Device Server User Guide
19
To install the unit
1. Connect a serial device to your XPress DR. See
information about cable and connector specifications.
2. Connect an Ethernet cable to the Ethernet port.
3. Supply power to your XPress DR using a 9-30VDC or 9-24VAC source.
Note:
The required input voltage is 9-30VDC, 9-24VAC (3 W maximum).
4. Supply power to the serial device.
Note:
Connecting a device to an active Ethernet network can disrupt communications on the
network. Make sure the device is configured for your application before connecting to an active
network.
Required Information
Before configuring the XPress DR device server, have the following information available:
Hardware Address
Take note of the unit’s hardware address (also known as the Ethernet or MAC address.) It is on
. The first three bytes of the hardware Address are fixed and read
00-80-A3, identifying the unit as a Lantronix product. The fourth, fifth, and sixth bytes are unique
numbers assigned to each unit.
00-80-A3-21-18-17
or
00:80:A3:21:18:17
Internet Protocol (IP) Address
The XPress DR device server must have a unique IP address on your network. This address
references the specific unit. By default, the unit is DHCP-enabled and automatically assigned an
IP address on DHCP-enabled networks. If you are assigning a static IP address, the systems
administrator generally provides the IP address, subnet mask, and gateway.
Note:
The factory default IP address is 0.0.0.0 to enable DHCP, BOOTP, and AutoIP. When the
units boots, it sends a DHCP broadcast to try and get an IP address. If it receives no reply from a
DHCP server, the XPress DR tries BOOTP. If the XPress DR does not receive a response from
BOOTP, it reverts to an AutoIP address.
IP Address:

Subnet Mask: ______ ______ ______ ______
Gateway: ______ ______ ______ ______
You have several options for assigning an IP address and related network settings to your unit.
This chapter provides information about using the DeviceInstaller (graphical user interface) and
serial port login (command line interface) methods.
Note:
For information about other methods of assigning the IP address, such as DHCP, AutoIP,
ARP, and Telnet, see
Alternative Ways to Assign an IP Address.
Port Number
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.
