Appendix A: Connecting to the Server

The EM-483 has a continuous communication mode with the data acquisition and management server. The server can be, for example, the Overvis system (Internet-address «overvis.com»).

About Overvis

Section titled “About Overvis”

Overvis is a system for monitoring and remote control of technological processes. Overvis allows you to:

  • Read data and manage devices including EM-483 when connected to them
  • Save data and then convert and view them in a convenient form
  • Receive alerts about accidents in the form of SMS or E-Mail

The factory settings of EM-483 are prepared for connection to Overvis.

Product Registration

Section titled “Product Registration”

The Overvis system supports a special identification method used in the product. In this case, the products are recognized by a unique MAC address, which is transmitted to the server each time you connect.

There are two ways to register the product for the user of the Overvis system:

Option A: QR Code Registration

Section titled “Option A: QR Code Registration”

If the product has a sticker with a QR-code, read the code and click on the link or enter the link from the sticker manually and then follow the instructions of the server.

Option B: Activation Code Registration

Section titled “Option B: Activation Code Registration”

Specify the activation code in the Overvis user account. The code is a number of 8 characters displayed on the status page of the product WEB-interface after connecting to the server. When you enter the code, the EM-483 “links” to the user account.

Connecting a New Product to Overvis

Section titled “Connecting a New Product to Overvis”

To connect a new product to the Overvis system using an activation code, you must:

  1. Connect the EM-483 to the Internet using one of the above methods.

  2. Make sure (on the product WEB-interface status parameters page, in the «Data Collection Server» field), that the connection to the server is established and the activation code is received.

  3. Using the instructions on the Overvis website, connect to EM-483 with the activation code.

  4. After activation, the status page will display the message «Active».

The message «No Code» means that the product was registered using the QR-code on the sticker.
