A computer with an RS232 port and a serial cable is required. To use the RS485 port at the back of the relay, a GE Multilin
F485 converter (or compatible RS232-to-RS485 converter) is required. See the F485 instruction manual for details.
1. Connect the computer to the F485 and the F485 to the RS485 terminal on the back of the UR device, or connect
directly the computer to the RS232 port on the front of the relay.
2. In the EnerVista Launchpad software on the computer, select the UR device to start the software.
3. Click the Device Setup button to open the Device Setup window, and click the Add Site button to define a new site.
4. Enter a site name in the Site Name field. Optionally add a short description of the site along with the display order of
devices defined for the site. This example uses "Location 1" as the site name. When done, click the OK button. The
new site appears in the upper-left list in the EnerVista UR Setup window.
5. Click the Device Setup button, then select the new site to re-open the Device Setup window.
6. Click the Add Device button to define the new device.
7. Enter a name in the "Device Name" field and a description (optional) of the site.
