USB5131 :: DCF77 Radio Clock for the Universal Serial Bus (USB)
Product Description
The device has now been redesigned to incorporate a Micro-USB 2.0 connector that supplies it with the power needed to operate it.
Four LEDs provide a visual indication of the current status of the DCF600USB, for example showing the rhythm of time marker demodulation and the clock synchronization status.
A buffered real-time clock maintains the clock accuracy while the device is powered off. The power required to run the DCF600USB is supplied by the USB port and no external power supply is required.
The Windows driver package includes a time synchronization service which runs in the background and adjusts the Windows system time continuously and invisibly. This package also includes a monitor program to enable the user to check the status of the device and time adjustment service. If the monitor program is run with administrator rights, it can also be used to modify configurable parameters.
The Linux and FreeBSD driver packages include a kernel driver which allows the product to be used as a reference time source for the NTP daemon included in most Unix-like operating systems. This also allows the computer to be used as an NTP time server to provide accurate time to NTP clients on the network. Some command line tools can be used to modify configurable parameters and monitor the status of the clock in use.
The Meinberg Single Driver Concept simplifies driver installation dramatically—one driver supports every Meinberg PCI and USB device, and if you use our free API to access your Meinberg synchronization device from within your own applications, you can use the same source code for both PCI and USB devices.
