4.23.5 Remote access
If the logger has FW V3.0B1 or newer, remote access to the data logger can be scheduled by
ydocTerminal V3.0. using our secure tunnel server (tunnel.ydoc.biz).
Note:
The data logger should be configured to use NTP time synchronization.
Within ydocTerminal click: File->New->Schedule a remote connection.
Specify the S/N of the data logger you want to access
and when you think it’s a convenient moment to
access the logger.
Obviously
: A tunnel cannot be established before the next scheduled data transfer interval of the data
logger.
A tunnel can only be established if ydocTerminal is running at the scheduled moment. When running,
ydocTerminal will pop-up a terminal window a few minutes before the scheduled moment.
Type of Server:
HTTP or HTTPS
Server address
: The HTTP-server must honor POST requests from ydocTerminal at the specified URL.
ydocTerminal will POST the request with
‘content-type:
text/x.tlr
’
. The S/N of the concerned data logger
is given in the custom HTTP-
header ‘X-DeviceSN’ The tunnel link request string itself is contained in the
body of the POST. This request string should be stored until the concerned data logger performs a POST
itself (its log data). The HTTP-server should copy the request string as the value of the custom HTTP-
header ‘X-Command’ in the response to the data logger.
User/Password:
Specify the exact same credentials as used by the data logger as they are a/o used in
the encryption keys.
Tunnel Server Properties
This is the Server servicing the secure and encrypted channel between data logger and ydocTerminal.
Standard our server is used (tunnel.ydoc.biz
), don’t worry we can’t eavesdrop your data as the
communication is ‘Peer-to-Peer’ encrypted by security keys not know to the tunnel server. If having
doubts, please feel free to run your own tunnel server, please ask our staff how to do it.
