| Further Information | The PCI511 has been designed for the reception of the DCF77 signal, the transfer of the time information to a computer with PCI (PCI-X) bus interface and the translation of the received codes into a serial telegram.
Because the radio clock PCI511 is composed as an universal board for computers with PCI bus, operation within 3.3V and 5V systems is possible. The drivers package for Windows contains a time adjustment service which runs in the background and adjusts the Windows system time continuously and smoothly. A monitor program is also included which lets the user check the status of the device and the time adjustment service, and can be used to modify configurable parameters, if run with administrator rights. The driver packages for Linux and FreeBSD contain a kernel driver which allows the board to be used as a reference time source for the NTP daemon which is shipped with most Unix-like operating systems. This also turns the computer into an NTP time server which can also provide accurate time to NTP clients on the network. Some command line tools can be used to setup configurable parameters and monitor the status of the board. For usage of the card on other operating systems please contact Meinberg support: techsupport@meinberg.de. The device's serial port is not required for operation but can be used to update the card's firmware, or provide another computer with the current time via a serial time string. |
