10. Printer
FDS offer a dedicated thermal printer which can be connected either to the TBox via its RS232
port or via Bluetooth using one of our iOS timing applications. In case of a TBox direct
connection, all the TBox generated time stamps will be printed, as well as the synchro time and
the GPS status if used in synchro.
The user can also reprint all times stamps of the run. Whilst pressing and holding down the
ON/OFF button, press the manual input 1 switch.
