One/Two/Four Port
Quick Installation Guide

Congratulations on your purchase of a LAVA Ether-Serial Link.
Ether-Serial Links connect serial devices to Ethernet networks. Any
serial device—POS equipment, factory machinery, monitoring
hardware, or security devices, for example—can send its
information to the Ether-Serial Link.The Ether-Serial Link places the
serial data in a TCP/IP wrapper and sends it out its Ethernet port.
Data moving the other direction, from the Ethernet side of the
Ether-Serial Link to the serial device, undergoes the same process in
reverse. LAVA Ether-Serial Links use industry-standard hardware
interfaces and are supported in Windows® NT4,Windows®2000,
Windows® XP,Windows® 2003, Linux, and QNX.
With a LAVA Ether-Serial Link, you can:
• Network serial devices
• Make devices available to multiple users
• Manage multiple serial devices from a single PC
• Eliminate long dedicated serial runs
• Stop using costly PCs as dedicated serial port servers
• Remotely access and control serial devices
• Eliminate long-distance phone-modem charges
Included with your package, you should have the following:
• LAVA Ether-Serial Link
• Power supply
• Quad DB-9 cable (4-DB9 Cabled version only)
• Installation diskette
• Quick Installation Guide
Getting Started
Hardware Setup
2
1. Connect the power supply to the Ether-Serial Link and to AC
power.
2. The power (red) LED will light to indicate that the unit is
receiving power.
3. Connect a network cable to the Ethernet RJ-45 jack of the
Ether-Serial Link.The other end of the network cable can be
attached to either:
• an Ethernet hub or switch, using a length of standard
Ethernet network cable
• a host PC directly, using an Ethernet cross-over cable.
Network status is indicated by two LEDs on the RJ-45 connector.
The left (yellow) LED indicates network activity. It is on by default,
turning off when network activity occurs at the Ether-Serial Link.
The right (green) LED indicates a network link. It is off by default,
but lights when a network link exists.

Software installation and configuration consists of the following:
A. Running the Ether Link setup software
B. Configuring network settings
C. Activating and deactivating Ether Link ports
D. Optional advanced port configuration
E. WAN configuration
F. Upgrading software
The installation diskette has files to install Ether Link drivers on your
PC and to detect Ether Links on your network.To run the
installation software, insert the installation diskette and run
"Setup.exe".The
Setup Wizard will ask
you to supply basic
installation
information.
The Setup Wizard will
finish by opening the
Lava
. By default
the
will display
Lava Ether Link
devices that it has
detected on your
network.

B. Configuring network settings
The Lava displays Ether Link information in a
Windows Explorer-like interface. Any Lava Ether Links that are
discovered on your network are displayed in the "Ether-Links Near
Me" branch of the "My Ether Link Network" tree.
Ether Link devices installed on your network will need unique IP
addresses.These can be set by using either the
a web browser, or a Telnet client.
The factory default network settings for the Ether-Serial Link are:
IP address: 192.168.0.35
Subnet mask: 255.255.255.0
Gateway address: 0.0.0.0
Name: [empty]
Workgroup: [empty]
DHCP detection: disabled

Before Proceeding:The Ether-Serial Link is factory preset with an IP address of
192.168.0.35. If this IP address cannot be used on the network (it may already
in use, for instance), do not initially connect the Ether-Serial Link to the
network. Instead, either:
1) connect the Ether-Serial Link to a network segment that is not already
using the Ether-Serial Link default IP address for another device or,
2) connect the Ether-Serial Link directly to a host PC using an Ethernet
crossover cable.
Follow the procedure described in the "Configuring network settings" section
of this manual to set the IP address to a usable address for the network onto
which the Ether-Serial Link will be installed.
Configuring Ether Link network settings using the Ether Link
Manager
To set an Ether Link's network
settings using the
, right-click on it in the
Ether Link tree and select
“Properties”. If the Ether Link is
accessible on the network, a
dialog will open that allows you
to give it a new name, IP
address, subnet mask, and
gateway address. If your
network assigns IP addresses
using a DHCP server, DHCP
detection can also be enabled.
The can also
auto-configure a link when a
DNS server is used.
Changes made using the
will be updated
to both the local PC and to the
Ether Link.
Changing the network settings of an Ether Link device may
make that device unavailable to other stations that have activated
a connection to that device using older network settings.
The is the recommended method of
changing all Ether-Serial Link settings.

Configuring Ether Link network settings using a web browser
To set an Ether Link's network settings using a web browser, open
the browser and
enter the IP address
of the Ether Link into
the browser's location
bar.The embedded
web server running
on the Ether Link will
display the opening
screen of the Ether-
Serial Link
configuration menu.
Choose the setting
you wish to change.
In the configuration screen that appears, enter the network settings
you wish for that Ether Link. Once the new values are entered and
accepted, the Ether-Serial Link will reboot to implement the new
network settings.
Changes made using a web browser will be updated to the Ether
Link but not to the local PC.
Changing the network settings of an Ether Link device may
make that device unavailable to other stations that have activated
a connection to that device using older network settings.
NOTE:

Configuring Ether Link network settings using a Telnet client
Note on subnet configuration
To set an Ether Link's network
settings using a Telnet client,
open a Telnet session to the IP
address of the link whose
settings you want to change.
Details on Telnet connection
can be found in the“telnet.pdf”
file on the Installation diskette.
If the Ether-Serial Link is on a different subnet from a client station
that is attempting to access it, the Ether-Serial Link will be visible in
an instance of the LAVA Ether Link Manager running on the client
station, and its ports can be activated on that client station, but
applications running on the client station will not be able to open a
serial port on the Ether-Serial Link.
For example, if the IP address of the Ether-Serial Link is 192.168.0.35
and the IP address of the client station is 192.168.1.1, the two
devices are on different subnets (as indicated by the difference
between the "0" and the "1" in the third portion of the two IP
addresses).
Two solutions exist:
• change the subnet of the either the Ether-Serial Link or the
client station so that they are both on the same subnet or,
• change the subnet mask of the Ether-Serial Link to encompass
both subnets. By default, the Ether-Serial Link has its subnet
mask set to 255.255.255.0.This setting excludes all but the
fourth portion of the IP address when assessing IP addresses. In
the example above, a subnet mask of 255.255.0.0 will include
the Ether-Serial Link in both subnets.

C. Activating & Deactivating Ether Link ports
Ether Link ports that have been detected as existing on the
network are not initially activated for your PC.To access an Ether-
Serial port it must be activated.You may wish to activate on a given
computer some, all, or none of the Ether Link ports that are
available on the network.To activate a particular port, right click on
the port where it is displayed in the right panel of the
, and select "Activate".To activate all ports on a particular
Ether-Serial Link device, right click on that device in the left panel of
the and select “Activate All”.
Before activation, Ether Link ports only appear under the "My Ether
Link Network" branch of the Ether Link Desktop. Once they have
been activated for a local system, they will also appear under "My
Computer" in the .
To deactivate ports
individually, right-
click on the port
where it is displayed
in the right panel of
the
, and select
"Deactivate".To
deactivate all ports on a particular Ether-Serial Link device, right
click on that device in the left panel of the and select
“Remove All”.
