MSF51USB:
MSF Radio Clock for the Universal Serial Bus (USB)

The MSF51USB is a perfect alternative for synchronizing computer systems where no PCI slot or serial port is available for time synchronization.
This Product is replaced by MSF600USB - MSF Radio Clock

Key Features:

  • Universal Serial Bus (USB)
  • Powered by USB (no extra power supply required)
  • Receiver status LEDs
  • Buffered hardware clock
  • Connector for external MSF antenna
  • Plastic Case
  • 2 years warranty

The radio remote clock MSF51USB has been designed for communication via the USB interface. The required power is provided via the USB cable as well, so there is no need for any external power supply.

The MSF signal received by the internal antenna is passed to the on-board LF receiver where it is demodulated by a synchronous detector with automatic gain control. The demodulated time marks from the receiver circuit are filtered and decoded by the microprocessor. If no errors are detected in the current time message an additional plausibility check against the previous time message is performed. If that plausibility check passes, too, the real time clock on the board is adjusted corresponding to the decoded time and date.

The MSF51USB module provides two integrated LEDs, which show the demodulated time marks (MOD LED) and the state of synchronisation (FR LED).

The scope of supply includes an USB cable with 3 mtrs. of length to connect the MSF51USB directly to a PC’s USB port. Also included is the driver software for Windows 2000/XP/VISTA® operating systems that is used to set the system time of the computer and shows the important status information of the MSF51USB.
