1. Connect the power supply to the NETRS232 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 NETRS232.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 NETRS232.The right (green) LED indicates a network link. It is off by default, but  
lights when a network link exists.

Software Installation  
and Configuration  
3
Software installation and configuration consists of the following:  
A. Running the NETRS232 setup software  
B. Configuring network settings  
C. Activating and deactivating NETRS232 ports  
D. Optional advanced port configuration  
E. Upgrading software  
A. Running the NETRS232 setup software  
The installation diskette has files to  
install NETRS232 drivers on your PC and  
to detect NETRS232 devices 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 IP-Extender Manager. By default the  
IP-Extender Manager will display  
NETRS232 devices that it has detected on  
your network.  
B. Configuring network settings  
The IP-Extender Manager displays NETRS232 information in a Windows Explorer-like  
interface. Any NETRS232 devices that are discovered on your network are displayed in  
the "IP-Extenders Near Me" branch of the "My IP-Extender Network" tree.  
NETRS232 devices installed on your network will need unique IP addresses.These can  
be set by using either the IP-Extender Manager, a web browser, or a Telnet client.  
The factory default network settings for the NETRS232 are:  
IP address:  
Subnet mask:  
192.168.0.35  
255.255.255.0  
Gateway address: 0.0.0.0  
Name:  
Workgroup:  
[empty]  
[empty]  
DHCP detection: disabled

Before Proceeding:The NETRS232 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  
NETRS232 to the network. Instead, either:  
1) connect the NETRS232 to a network segment that is not already  
using the NETRS232 default IP address for another device or,  
2) connect the NETRS232 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 NETRS232 will be installed.  
Configuring NETRS232 network settings using the IP-Extender Manager  
To set a NETRS232's network settings using the IP-  
Extender Manager, right-click on it in the IP-Extender  
tree and selectProperties. If the NETRS232 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.  
Changes made using the IP-Extender Manager will  
be updated to both the local PC and to the  
NETRS232.  
NOTE: Changing the network settings of a NETRS232 device may make that device  
unavailable to other stations that have activated a connection to that device using  
older network settings.  
NOTE: The IP-Extender Manager is the recommended method of changing all  
NETRS232 settings.  
Configuring NETRS232 network settings using a web browser  
To set a NETRS232's network settings using a web browser, open the browser and  
enter the IP address of the NETRS232 into the browser's location bar.The embedded  
web server running on the NETRS232 will display the opening screen of the NETRS232  
configuration menu.  
 
5
Choose the setting you wish to change.  
In the configuration screen that appears,  
enter the network settings you wish for  
that NETRS232 device. Once the new  
values are entered and accepted, the  
NETRS232 will reboot to implement the  
new network settings.  
Changes made using a web browser will  
be updated to the NETRS232 but not to  
the local PC.  
NOTE: Changing the network settings of  
a NETRS232 device may make that device  
unavailable to other stations that have  
activated a connection to that device using older network settings.  
Configuring NETRS232 network settings using a Telnet client  
To set a NETRS232'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 thetelnet.pdffile on the  
Installation diskette.  
C. Activating & Deactivating NETRS232 ports  
NETRS232 ports that have been detected as existing on the network are not initially  
activated for your PC.To access a NETRS232 port it must be activated.You may wish to  
activate on a given computer some, all, or  
none of the NETRS232 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 IP-Extender Manager, and select  
"Activate".To activate all ports on a  
particular NETRS232 device, right click on  
that device in the left panel of the  
Manager and selectActivate All.  
Before activation, NETRS232 ports only appear under the "My IP-Extender Network"  
branch of the IP-Extender Desktop. Once they have been activated for a local system,  
they will also appear under "My Computer" in the IP-Extender Manager.  
To deactivate ports individually, right-click on the port where it is displayed in the right  
panel of the IP-Extender Manager, and select "Deactivate".To deactivate all ports on a  
 
6
particular NETRS232 device, right click on that device in the left panel of the Manager  
and selectRemove All.  
Icons depict the states of NETRS232 devices and ports as follows:  
Device available  
on the  
Device not  
available on the  
network  
UnderMy Computer”:  
Port available  
UnderMy Computer”:  
Port not available  
network  
UnderMy Ether Link Network”:  
Port activated locally  
UnderMy Ether Link Network”:  
Port not activated locally  
Activated ports appear in WindowsDevice Manager under the "Ports (COM & LPT)"  
branch as "IP-Extender" ports, with their associated COM numbers.  
Activating and deactivating NETRS232 ports on one computer does not affect the  
operation of those ports on other systems.  
D. Optional advanced port  
configuration  
NETRS232 ports that have been activated  
on your PC can generally be used  
immediately without further  
configuration. Additional configuration  
options can however be accessed  
through the IP-Extender Manager.These  
configuration options are discussed in  
detail in theadvanced.pdfreadme file  
on the Installation diskette.  
Advanced settings include passwords;  
port binding options that can associate a  
port with a specified IP address, NetBios  
name, or MAC address; port modes for  
raw server or client connection, Ethernet  
modem operation, RFC 2217  
communications, data connect  
operation, or RAS server  
communications; and a COM port  
number reassignment feature.  
E. Upgrading software  
 
This device complies with part 15 of the FCC Rules. Operation is subject  
to the following conditions: (1) This device may not cause harmful interference,  
and (2) this device must accept any interference received, including interference  
that may cause undesired operation.
