Zhongxin Chuangwei provides a precision clock to Gaoyang County Hospital.

Recently, Gaoyang County Hospital issued a procurement announcement for a time server. Beijing Zhongxin Chuang Company proactively collaborated with the hospital to develop a detailed proposal and recommended its independently developed and manufactured DNTS‑8 model 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 the Gaoyang County Hospital time‑server project.

Gaoyang County Hospital was founded in October 1948, originally located on West Street in Gaoyang County. In 1956, it was reorganized as Gaoyang County Hospital and has since undergone several name changes, including “Gaoyang County Health and Disease Prevention Institute” and “Gaoyang County People’s Hospital.” In 1961, the hospital relocated to the former site of the Power Plant, at the northwest corner of its current location. Following several renovations and expansions, it has now evolved into a modern, comprehensive Grade II-A hospital, featuring an outpatient building, inpatient wards, an administrative office building, and an infectious disease building. With the continuous improvement of the national medical security system and growing expectations for the development of county-level hospitals, the hospital has been actively planning a full-scale relocation project since 2009, aiming to meet the increasing healthcare needs of residents in Gaoyang County and neighboring areas.

Gaoyang County Hospital conducted an in-depth evaluation of the DNTS-8 time server, independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, and the hospital expressed high satisfaction with both the product’s quality and our after-sales service, leading to a successful procurement and deployment.

The DNTS-84-OGB 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-84-OGB time server obtains standard clock signal information from GPS or BeiDou 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 both GPS and BeiDou receivers are in use, a priority can be configured; by default, BeiDou takes precedence, with GPS serving as a backup. If neither receiver receives a signal, the DNTS-84-OGB relies on its built-in temperature-compensated crystal oscillator for timekeeping, achieving a timing accuracy of up to 1E-9. The DNTS-84-OGB disseminates standard clock information over TCP/IP networks and supports multiple popular time‑broadcasting protocols, including NTP and time/UDP, as well as Zhongxinchuang’s proprietary time‑broadcast data packets with 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-84-OGB supports the broadcast mode of the SNTP protocol.

Product dimensions	19-inch 1U
Receiver	Built-in GPS and Beidou 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 the 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, hold‑over 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 precision of the temperature-compensated crystal oscillator reaching 1E-12 or better.
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 days (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
