PCI511: DCF77 PCI Computer Clock (PCI/PCI-X Bus)



The PCI511 is a DCF77 radio clock for synchronisation of computers with a PCI or PCI-X slot. It receives the longwave radio time signal from the DCF77 sender located near Frankfurt/Main, Germany.

Warranty Period (Years): 3 RoHS-compliant



Product Description

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 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.

Please contact Meinberg's Support Team for more information on using the card with other operating systems: techsupport@meinberg.de.

The device's serial port is not required for operation but can be used to update the card's firmware, or to provide another computer with the current time via a serial time string.
