The device is assigned a fixed IP within a VPN (Virtual Private Network), so real-time communications are possible by sending commands to which a response is returned in the same way as the local COM port.

Since the API call requires the password:

  • no need to login
  • commands can be sent without the leading password

An additional custom header is returned:

  • X-EstimatedDataVolume
    reports the estimated data traffic volume (bytes) generated by API call, including:
    - data sent
    - data received
    - data overhead
