1. Switch to Restore Default Settings - This switch can be used to  
reset the product to its factory default settings. Pressing the switch  
using either a pen or similar tool will immediately restore the unit  
to its default settings.  
2. RJ45 LAN Connector - 10/100Mbps Ethernet port. It supports the  
auto cross-over feature, and allows use of the same cable to  
connect to either a Hub/Switch or a host computer.

Hardware installation  
1. Use static electricity discharge precautions. Remove possible static  
discharge potential from any objects that the adapter may come in  
contact with prior to installation. This can be accomplished by  
touching a bare metal chassis rail after you have turned off the  
power.  
2. If you will be externally powering the device, connect the DC power  
adapter. If connecting to a PoE switch, hub, or other device, then  
a power adapter is not required, as the product will draw its power  
from the host device it is connected to. In this case, ensure that  
your switching hub is the PoE type that can act as PSE (Power  
Source Equipment).  
3. Connecting LAN cable: Use a standard straight-through Ethernet  
cable to connect to a Hub or Switch. If you connect the adapter to  
your computer’s Ethernet port instead, you don’t need to change to  
a cross-over type cable since the adapter provides the auto cross-  
over feature.  
4. Connect the Adapter’s serial port to your serial device.  
5. Use the DIN RAIL mounting Kit if you want to place the product on  
the industrial DIN RAIL. (optional)  
Configuring the Adapter  
Setting the IP Address  
Please consult your Network Administrator to determine the appropri-  
ate IP address. The adapter comes with the factory installed IP address  
192.168.1.254. It is ready to accept a new IP address from a DHCP  
Server. If your network has a DHCP server, it will automatically assign  
an IP address to the Adapter the first time it is connected and powered  
up.

1. Setting the IP Address from a DHCP Server  
A DHCP server will automatically assign an IP address (dynamic  
address) as well as Subnet Mask and Gateway to this adapter. If you  
power up the Adapter without a fixed (static) IP address, the DHCP  
server will be able to assign an IP address (Note: By default, DHCP  
is disabled. If you wish to support DHCP, Enable it in the Adapter  
Setup Menu).  
Note: If you will set the IP address using another method, you will need  
to use a static IP address. To do this, Disable DHCP (this is the default  
setting) in the Adapter Setup Menu.  
2. Setting the IP Address using a Web Browser  
Please ensure that your PC’s IP address is set to the same subnet  
as the adapter. If not, you will need to change your PC’s IP address  
from the Local Area Connection Properties menu, shown below:  
Run your browser and access the product by entering the default  
(192.168.1.254) or current IP address into your browser’s address  
window. Enter the password (default has no password), then go to  
Change your IP Address, and make the necessary changes.  
5
 
3. Setting the IP Address using the Em.exe Utility  
The Em.exe is a Microsoft Windows based utility used to identify the  
adapters connected on the same subnet and network segment. To  
run the Em.exe utility, please insert the driver CD supplied with the  
Adapter. Open the program at the following location (assume the  
CD-ROM drive is at E):  
E:\IO_over_IP\Utilities\Em\Em.exe  
Managing the Adapter Settings  
When you enter the Adapter Setup Menu, the following page will be  
available for your access. By default there is no password for entry.  
Once you have entered the Controller Setup Menu and made the  
necessary changes, click the Update button. Also ensure that you  
make note of your password as you will need it to enter the setup menu  
again.

Software Installation  
VSP Virtual COM Port Driver  
The VSP is a redirector driver that allows your applications to use  
serial devices provided by serial device servers on your network. This  
redirection is achieved by creating one or more virtual COM port(s) that  
allow these networked serial devices to function as though they are  
directly connected to the local computer.  
Since the redirector’s virtual COM port(s) function much like standard  
Windows COM ports, your application software sees no difference  
between a local serial device and one provided by a serial server.

Installing the VSP Virtual COM Port Driver  
1. Locate the necessary Software in the following folder on your driver  
CD. The VSP COM.exe is the redirector software. The Em.exe is  
used to setup the hardware mode to support VSP redirector.  
2. Configure your hardware mode to support VSP.  
Run the EM.exe application to find the device hardware.  
Enter the setup menu by double clicking the listed hardware.  
Click Login (by default settings, there is no password).

Change the settings to COM Port, save the changes, and exit the  
setup menu.  
3. Run the VSP Setup Program.  
Double click the VSP COM.exe application in the VSP folder  
on the supplied CD.You may receive a message indicating that  
this driver has not yet passed Windows logo testing. If so, click  
Continue Anyway.  
Select the COM ports to be redirected by checking the boxes  
next to them:

Set the COM Port settings: The following figure shows only one  
COM port setting being changed.You may have 4 COM ports  
(or 1, 2 ports depending on the model), you will need to set it 4  
times for, once for each COM port.  
Checking the Installation: Go to the Device Manager (right click  
My Computer, Hardware, Device Manager) to check the  
installation, a successful settings will look something like the  
following figure:
