VPN TERMINAL
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
