CLOCK77/PCI PCI DCF-77 radio clock on a PCI PC card

The reliable and budget priced Clock77 radio clock supplies the atomclock exact time over the ISA bus. A switching from and to summer time is not nescessary.

The accuracy of the radio clock's time is +/- 50 ms. Windows 95 / 98 / ME / NT 4.x / 2000 / XP drivers (server and workstation) are available. For Windows XP / 2000 / NT 4.x the Clock77 software is executed as "NT service".

Therefore, the time will be updated even when no user is logged in.

We added a graphical monitor program which allows to check the positioning and the quality of the received signal. This is nescessery for adjusting the clock in distorted or large distance locations. The clock incorporates a highly intelligent algorithm for the dectection of faulty times and the correction of them.

You can distribute the received time easily to other clients in the network. The manual describes how to do this.

The new enhanced antenna now gives a larger covered area and has a built in LED for function control.

The QUANCOM drivers need very little processing time and save processor resources. You will not detect any essential system impact.

Additional information
•Description	The CLOCK77/ISA and CLOCK77/PCI radio clocks consist of a small card for the PC bus and a receiver. It is connectad via an approx. 5m cable and a DSUB interface to the card. All necessary signals and the power supply is supported by the PC bus. With this easy-to-install clock usable on any computer system you always have the exact time. The CLOCK77 is supplied as an ISA as well as a PCI version. With the card, you get the receiver module, a manual, drivers for Windows XP / 2000 / 98 / 95 / DOS and NT 4.0, background services and a DOS background program ( german language ). Receiving the time is done in the background without interrupting the working. The NT receiving program is executed as "NT service". Therefore, the time can be set even when no user is logged in. One of the most important factors concerning the decision which radio clock to buy should be (exept for the precision of the clock) if the driver affects the system perfomance. By putting the Clock77 on a slot card, we succeeded in reducing the impairment of the system perfomance to a minimum. The precision of the clock is +/- 50ms difference to the received time. The received time can be automatically distributed to Windows Clients. Thus, the syncronisation of an unlimited number of computers on a network with the time received is guaranteed. The necessary steps arte described in the manual. For all users of other systems, we supply the C source code. It clearly shows how to receive the time and how easy it is to integrate the Clock77 into non-DOS systems.

•Functions	The system time is set by the driver at regular intervals. If the complete time information has been received without any disturbing, the software sets the PC clock to the received exact time and date value. In the daily use this means for the user that he does not have to struggle with wrong date and time settings on the PC any more. If connected to the PC and reguarly installed once, even the annoying switching to summer or winter time are not necessary. The signals received by the Clock77 from the german Mainflingen take care that this is done automatically.
