So This Is Christmas

Merry Christmas is such an infectious feeling I like to feel that way all year around.

So if you are visiting just before Christmas, just after Christmas or even here on Christmas day I am sure you will find something of interest for you and in the spirit of Christmas.

It may be said that Christmas is no longer a celebration but this must be spoken by people that have never had trouble closing their eyes on Christmas Eve in an expectation of what maybe left for them on the carpet under the tree.

I continue to look forward to the surprise on my Grandchild's faces to this day at Christmas events.

Merry Christmas - Merry Christmas - Merry Christmas

Wall Clocks, the Ethernet Digital Wall Clocks

By Ali Mulyadi

If you are worrying about your digital wall clocks configuration then worry no more because it really is simple. You can configure a NTP digital clock from any telnet session. You can use your own PC to login to your network, find the device and begin configuration.

The accurate display is obtained from a NTP (network time protocol) or a SNTP (simple network time protocol). Both the NTP and SNTP can be internet/Intranet based. If you give your digital wall clocks an IP address then they will automatically synchronize with that IP's time settings.

Digital wall clocks come with two different display options. One is four digits and the other is six digits. This allows the clocks to display hours, minutes and seconds. The Ethernet NTP digital clocks can even be programmed so that they change time with daylight savings.

The four digit display on digital wall clocks show only the minutes and hours whereas the six digit display on digital wall clocks show hours, minutes and seconds. These two displays come in bold 4 inch high LED lights and as such they can be seen from as far as 50 meters away.

All digital clocks that are NTP enabled will also have PoE. This allows the power from the Ethernet to power the clock should the mains cut out. This simplifies installation and only uses a CAT5 cable to power the unit. With PoE you will no longer need a mains outlet where you intend to site the clock.

If your network is PoE enabled then you can plug and go with your digital wall clocks but if you do not have a PoE network then you can always opt for a midspan converter which is the equivalent to a small power supply.

You can mount these clocks in any way that you like. You can choose to wall mount it (most of the Digital wall clocks will come with two pre drilled holes, some come with a more sophisticated mounting system). With some clocks you can even invest in a mounting kit that will allow you to suspend them from the ceiling.

The ceiling mounting kits are designed so that you can use either one or two digital wall clocks (two clocks back to back) to show across the office/ warehouse in two directions. You can adjust the times of these clocks independently with different time zones showing on each. This can all be done from a PC and therefore does not need to be monitored or need any additional software/hardware. They can even be set to change in accordance with daylight savings.
