Accessing the Main Page
The following steps will help you access the browser based configuration of the gateway. By default,
DHCP is enabled. If the gateway fails to obtain an IP address over DHCP it will Auto IP with 169.254.X.Y.
For more information on your Operating system network setting refer to the Access Browser
Configuration Doc on the CD or download from our support web site.
1) Insert the provided CD-ROM into a computer also on the network.
2) Run the IPSetup.exe program from the CD-ROM.
3) Find unit under “Select a Unit”.
a. Change Gateway’s IP address to match that of your PC if DHCP has failed.
i. You will know DHCP has failed if the gateway’s IP address is AutoIP at 169.254.X.Y.
ii. If successful, it will say DHCP’d at ex: 192.168.0.100 or however your DCHP Client is set up.
b. If you do not see the gateway in this tool, then your PC is most likely set up as a static IP.
i. Change your PC’s network settings to be DHCP. If DHCP fails, then it will change to be on the
169.254.x.y network.
ii. Relaunch the IP Setup tool to see if gateway can be discovered now.
4) Click Launch Webpage. The Main page should appear.
Default setting is set to DHCP. If DHCP fails, default IP Address is 169.254.x.y

Error: Main Page Does Not Launch
If the Main Page does not launch, please verify the following:
1) Check that the PC is set for a valid IP Address
a. Open a MS-DOS Command Prompt
b. Type “ipconfig” and press enter
c. Note the PC’s IP Address, Subnet, and Default Gateway
2) The gateway must be on the same Network/Subnet as the PC whether it’s setup for DHCP or Static.
Once you have both devices on the same network, you should be able to ping the gateway using a MS-
DOS Command Prompt.
The Screenshot above shows a gateway that is currently set to a static IP Address of 192.168.0.100.
If you are able to successfully ping your gateway, open a browser and try to view the main page of the
gateway by entering the IP Address of the gateway as the URL.

Committing Changes to the Settings
All changes made to the settings of the gateway in Configuration Mode will not take effect until the
gateway is restarted via the webpage. Changes will not be stored if the gateway’s power is removed
prior to a reboot.
NOTE: The gateway does not need to be restarted after every change. Multiple changes can be made
before a restart, but they will not be committed until the gateway is restarted.
When all desired changes have been made, press the Restart Now button.
The webpage will redirect to our rebooting page shown below:
The reboot can take up to 20 seconds.
If the IP address has not been modified, the gateway will automatically redirect to the main page.
If the IP address was modified, a message will appear at the top of the page to instruct the user to
manually open a new webpage at that new IP.

Device Configuration
The device configuration area is where you assign the device description parameter. Changes can only
be made when the gateway is in Configuration Mode.
Once you are done configuring the Description, click the Save Parameters button.
Network Configuration
The network configuration area is where you assign the IP address and other network parameters.
Changes can only be made when the gateway is in Configuration Mode.
Once you are done configuring the Network Settings, click the Save Parameters button.
If you are changing the IP Address of the gateway, the change will not take effect until the unit has been
rebooted. After reboot, you must enter the new IP Address into the URL.

Network Interface Options
The N2E hardware has two different Network Interface options, Independent and Switch Mode. Below,
you can find the different use cases that each interface option allows for.
Independent Mode
1) Two Ethernet-based protocols on the same IP Network
a) Ethernet Port 1 used OR
b) Ethernet Port 2 used OR
c) Ethernet Port 1 & 2 used
2) Two Ethernet-based protocols on different IP Networks
a) Ethernet Port 1 used AND
b) Ethernet Port 2 used
Switch Mode –Only Ethernet Port 1 is used for protocol communication
3) One Ethernet-based protocol on the IP Network (layer-2 switch)
a) Ethernet Port 1 used for direct protocol communication
b) Ethernet Port 2 available for daisy chaining devices together
i) A Ring topology is NOT supported
4) Two Ethernet-based protocols on same IP Network
a) Ethernet Port 1 used for direct protocol communication with another switch, hub, or router
b) Ethernet Port 2 available for a daisy chaining devices together
i) A Ring topology is NOT supported
5) Two Ethernet-based protocols on different IP Networks
a) Not Possible –must use Independent Mode
It is recommended to leave the DNS Gateway set to 0.0.0.0 and the Ethernet Link as
Auto-Negotiate. If configuring the gateway to use E-mail, the DNS Gateway must be
set.
