Hardware Installation on a laptop
1. To prevent IP address conflicts with your companies IP addressing it is required
that you install a USB to Ethernet adapter to your laptop. We have used the
TRENDnet TU2-ET100 available through Weco or directly from RadioShack.
2. Install the USB to Ethernet adapter and software per the manufacture’s
instructions.
3. After the USB to Ethernet adapter’s software is installed, connect the USB to
Ethernet adapter to your laptop.
4. Click on Windows Start button, and select Settings | Network Connections |
{your new USB to Ethernet adapter}.
5. From this screen select the Internet Protocol (TCP/IP) and then the properties
button.

[You may actually use any value between 1 and 254 for each of the 1’s, it

accept the default. The Default Gateway should remain blank.

How to Use
1. Power up both your laptop and WE-20.
2. Connect an Ethernet cable between the laptop USB to Ethernet adapter and
the WE-20’s Ethernet connection. You may use the supplied orange
crossover cable or any Ethernet cable as the adapter will auto-configure for
the cable type.
3. Wait at least 40 seconds after connecting the cable to both devices so that the
IP address negotiation can take place and finish.
4. Double click on the laptop’s WE20vnc desktop icon. This will configure the
comport and launch the VNC application.
5. Run the WE-20 as if you were using the unit without remote control. You
may choose to open Explorer on the WE-20 and map a drive to a shared
folder of your laptop so that you can save files directly to your laptop. Be
sure that you check the box to Reconnect at login so that the map will
present every time you connect using remote control.
6. When running with remote control, the meter programming comport has
been redirected to the optical coupler on the WE-20 so your programming
applications can communicated directly to the meter through the WE-20’
optical probe.
7. To close remote control, you may choose to Shutdown the WE-20 from it’s
main screen. This will shutdown the WE-20 and close the remote
connection. You may also just choose to close the remote session and leave
the WE-20 on by clicking on the Red X on the most outer window of the
VNC window.
8. Once remote control has been terminated then the comport is redirected back
to the physical comport on your laptop so that your meter programming
applications can be used with an external probe without the WE-20.
