Talk2M PRO

The Pro service of Talk2M provides secure on-demand access for a large number of remote machines and devices, ranging from a few hundred to several thousand. Combined with an eWON industrial router, it facilitates perfect integration with a large variety of PLCs and automated devices.

Additionally, Talk2M Pro enables several users to access many machines at the same time.
A fully detailed connection report itemized by machine is available each month. Now it is possible to provide Web API* features for third-party applications, which makes Talk2M Pro a powerful remote service platform that can grow with your needs.

eCatcher, the PC client client, provides an intuitive user interface for accessing a large number of machines and devices over the Internet. Users can work independently and manage their own accounts (other users and remote machines) without any need for IT experts. For example, user access can be restricted to a specific group of machines, and users can be granted or denied the ability to manage other users. This major breakthrough facilitates easy deployment while circumventing IT complexity. eCatcher is the engineer"s machines address book.

Talk2M FREE+

The Free+ service of Talk2M is an Internet connectivity tool designed to address the growing need for broadband and wireless access in the automation world for remote maintenance and access to remote equipment.

The key added value of Talk2M is full integration of IT security standards by enabling Internet tunneling between the user and the remote machine without requiring any changes to IT network security settings at either end. This major breakthrough facilitates easy deployment while hiding the complexity of the IT network infrastructure.

On request or permanently (depending on the integrated modem of the eWON unit), the eWON unit establishes a secure VPN connection to the Talk2M web server using a UDP or TCP HTTPS port, thereby passing through the firewall and proxy server. At the other end, the user establishes a secure VPN connection to the Talk2M web server. The Talk2M server acts as a relay to interconnect the two VPN tunnels. The information exchanged during the communication session is encrypted (128-bit SSL), and only authenticated users can connect to the eWON unit.


  • Get instant connection with machines at broadband speed
  • One click to connect within fully secure VPN tunnel
  • No need for IT experts" assistance
  • Keep track who access the machines with connections report
  • No initial investment, go for SaaS hosting
  • Start using Talk2M now, unlimited in time free service
