Digital clock system

Except for analog pointer clocks, all other clock products of Shandong Weishang Company use sheet metal forming technology for the chassis, with the exterior treated with spray coating or baking paint, and a colored mask installed on the front of the display. All digital sub clocks can be installed using hanging or wall mounted methods.

WeishangDigital clock systemThe NTP time transmission protocol is used to synchronize time through the LAN or the Internet. The NTP host can be either an NTP time server within the LAN or an Internet NTP time server.

Product Features:

1. High synchronization accuracy - using intelligent time compensation technology

2. Long visible distance and good angle - using high brightness LED and anti glare panel

3. Low power consumption - using dynamic scanning technology and can achieve timed switching

4. Constant current drive, bidding farewell to traditional voltage drive, greatly extending the lifespan of LED

5. Multiple timing methods - RS232/422/485, IRIG-B, CANBUS

6. NTP/SNTP network, wireless wifi, Zigbee

7. Can be equipped with GPS/Beidou/CDMA receivers to achieve long-term high-precision self travel time

8. Intelligent management - can communicate with the upper computer and monitor the running status in real time

9. Owners can freely choose the shape and color of the sub clock shell
