Resetting Parameters to Factory Defaults
At any moment, all of the GTR ETH board parameters can be restored to
the factory default settings. To do so:
1. Set Dip Switch S1 dip 1 = ON (located near RJ45 connector ) ;
2. Restart GTR ETH board;
3. Set Dip Switch S1 dip 1 = OFF ;
S1 dip 2 off = 100Mb (DEFAULT)
S1 dip 2 on = 10Mb

4 •Setup PC Connection
All the information in this quick guide require that the GEFLEX-ETH communicates with the host PC through a LAN
connection.
In this pages you’ll learn how to configure the PC to communicate with the GEFLEX-ETH using an Ethernet cross
cable or hub/switch. The following steps are based on a Windows XP system.
1. Open the Windows Control Panel and open the Network. Connections item:
2. If a Local Area Connection is already available, go to step 8.
Otherwise, run the “New Connection”wizard.

3. The following dialog box will appear. Click Next.
4. On the next dialog box, select the “Connect to the Internet”option and click the “Next”button.
5. On the next dialog box, select the “Set up my connection manually option and click the “Next”button.

7. When the last dialog box appears, click the “Finish”button.
8. Open the newly created connection (or the existing connection if you are coming from step 2) and click the
“Properties”button.
6. On the next dialog box, select the “Connect using a broadband connection that is always on”option and click the
“Next”button.

Click the “OK”button on all LAN setup dialog boxes.
9. Select the “Internet Protocol (TCP/IP)”item and click the “Properties”button.
10. If you have started from an existing connection, write down all of the TCP/IP parameters. You’ll need them later to
restore your LAN settings to the original parameters.
11. Select the manual settings and type in the following values:
IP address: 192.168.1.101
Subnet mask: 255.255.255.0

5 •Test Board Connection Using PING Command
1. Power up the board and verify the POWER led turn on.
2. Connect the GEFLEX-ETH to the PC through an Ethernet cross cable or hub / switch.
3. Open a Command Prompt window (on Windows XP, from the Windows Start menu, select Run, enter CMD and
click the “OK”button).
4. At the command prompt, type: PING 192.168.1.100
5. If the connection has been properly setup, the PING command will return a positive feedback.
6 •Connect the Board to Your LAN
Before connecting the GEFLEX-ETH board to your LAN, the IP address must be changed to match the LAN
settings.
To change the GEFLEX-ETH’s IP address, do the following.
1. With the GEFLEX-ETH still connected to the PC via the Ethernet cross cable or hub /switch, launch the
GtrEthConfig.exe utility that is located in the CD-ROM.
2. Set the Rotary Switch combobox to match your actual GEFLEX-ETH’s Rotary value.
3. Press the Discovery Net button. You can see actual IP address , subnet mask , default gateway and MAC
adress.
4. Set your parameter and after click on Send Data button.
5. Restart the GEFLEX-ETH Board.
6. Goto to step 2 if you want to see new parameter.
