4 Features: TCR51USB
4.9 Configuration of TCR51USB
The selection of the IRIG code and a possible offset of the received IRIG time to UTC must be set up by the
monitor software via the USB. In contrast to AFNOR NFS 87-500 the IRIG telegram containes only the day
of year (1...366) instead of a complete date. To ensure correct function of TCR51USB, the date stored in the
realtime clock of the board must be set when using IRIG codes therefore. This setting can be done by a terminal
software also.
If the time zone of the received IRIG code is not UTC, the local offset to UTC must be configured to en-
sure correct function of the driver software. If the local time zone is MEZ for example, the board must be set to
a local offset of ‘+60min’ (MEZ = UTC + 1 h).
