Remote Timer has been designed to be used when the distance between a timing gate and the timing center is above the range of radio transmission. This app will send all timestamps generated by a TBox to our Cloud server (either via a timing session or via a WebResult competition ID). Those timeStamps can be retrieved either by SmartChrono, by another Remote Timer app (in Receive mode) or by a computer using the dedicated "FDS Timing Server Interface" PC application.
