Zhongxin Chuangwei provides clock synchronization server equipment to Liugang Group.

Zhongxin Chuangwei provides clock synchronization server equipment to Liugang Group.

Recently, Liugang Group issued a tender for time servers. Beijing Zhongxin Chuang promptly collaborated to develop a detailed proposal and recommended its independently developed and manufactured DNTS-88-OGB time server as the bid‑winning product. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the contract for Liugang Group’s Beidou timing equipment project.

Guangxi Liuzhou Iron and Steel Group Co., Ltd. (hereinafter referred to as “Liugang Group”) is strategically located in the golden hub of China’s Pan‑Pearl River Delta, Greater Southwest, Beibu Gulf, and ASEAN economic circles. It ranks among the world’s top 50 steel enterprises, is listed among China’s Top 500 Enterprises, and is one of the 18 local steel companies designated in the national steel industry layout. The company is a super‑large integrated steel enterprise in China. In 2022, it was awarded an A+ (extremely strong) rating for competitiveness and development quality among Chinese steel enterprises, recognized as an outstanding enterprise in smart steel city construction, and became the nation’s first “cloud‑based steel plant.”

Liugang Group conducted an in-depth evaluation of the DNTS-88-OGB time server, independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, and the company expressed high satisfaction with both our product quality and after-sales service, leading to a successful procurement and deployment.

The DNTS-8 time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is a high-tech, intelligent, stand-alone clock synchronization server that operates based on the NTP/SNTP protocols and delivers high precision. The DNTS-8 time server obtains standard clock signal information from GPS geostationary satellites and transmits this information across the network, enabling devices requiring time signals—such as computers and controllers—to synchronize with the standard clock. When all receivers lose signal, the DNTS-8 relies on its built-in temperature-compensated crystal oscillator for timekeeping, achieving a timing accuracy of up to 1E-9. The DNTS-8 disseminates standard clock information via TCP/IP networks and supports multiple popular time‑broadcasting protocols, including NTP and time/UDP; it can also accommodate custom‑defined time‑broadcast packets using configurable UDP ports. The port numbers for NTP and time/UDP are fixed at 123 and 37, respectively, as specified in RFC-123 and RFC-37. Additionally, the DNTS-8 supports the broadcast mode of the SNTP protocol.

Product dimensions	19-inch 1U
Receiver	Built-in GPS receiver
Built-in clock	Built-in temperature-compensated crystal oscillator; even when satellite signals are lost, it continues to output a standard time signal.
Liquid crystal display	LCD displays time in two lines of 20 characters each, showing the current time, the number of satellites, and the device’s operating status. LEDs indicate power status, satellite lock status, holdover operation, alarms, and NTP validity.
Throughput	Can handle 2,000 time requests per second per port.
Local Alarm	Supports SNMP alarms, local dry-contact alarm output, current rating 10A.
Output interface	RS232/485, IRIG-B, 10M, 1PPS, 10 MHz sine wave output, BNC connector 1 PPS output, BNC connector IRIG-B code output, BNC interface IRIG-B code input, BNC interface RS232 output, supports the TL1 protocol.
Input interface	Serial port input; time can be set manually, and it can serve as an external clock source.
Timekeeping function	Even when satellite signals are lost, it must still output a standard time signal, with the temperature-compensated crystal oscillator achieving an accuracy of better than 1 × 10⁻¹².
Encryption Verification	Provides MD5 encryption verification functionality.
Network management functions	It features comprehensive SNMP network management capabilities.
Feature Expansion	Supports expanding to select other functional modules.
Settings Management	Supports configuration and management via web pages, Telnet, and other methods.
Timekeeping Record	Time‑synchronization logs can be viewed via the web interface and Telnet; the installed software can store an unlimited number of records.
UDP operating mode	Provides the UDP broadcast protocol, enabling connection to electronic clock LED displays. You can configure at least eight UDP remote IP addresses and port numbers: Output the newly created science and technology time data packet: A total of 32 bytes, with the following details: Offset Description 00...01 year (00...99) 02...03 months (01...12) 04...05 day (01...31) 06...07 hours (00...23) 08...09 points (00...59) 10...11 seconds (always 00) 12 weeks (1-Mon, 2-Tue, ...) 13 Daylight Saving Time Flag (0-no, 1-yes) 14 String terminator, ‘\0’ 15 String terminator, ‘\0’ 16...19 32-bit CET/CST time in UNIX format 20...23 32-bit GMT time in UNIX format 24...31 All 0
