Zhongxin Chuangwei provides precise clock synchronization for Chengdu Banknote Printing Co., Ltd.

Zhongxin Chuangwei provides precise clock synchronization for Chengdu Banknote Printing Co., Ltd.

Recently, Chengdu Banknote Printing Co., Ltd. issued a tender for a time server. Beijing Zhongxin Chuang promptly collaborated to develop a detailed proposal and recommended its self‑developed and manufactured DNTS‑6 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 the time‑synchronization server project from Chengdu Banknote Printing Co., Ltd.

Chengdu Banknote Printing Co., Ltd. is China Banknote Printing and Minting Corporation It is a large, integrated printing enterprise primarily engaged in the production of legal tender, encompassing anti-counterfeiting printing, the manufacture of specialized security papers, precious-metal processing, and power‑supply support.

Chengdu Banknote Printing Co., Ltd. conducted an in-depth evaluation of the DNTS-6 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, proceeding to place a successful order and put the system into operation.

The network time server DNTS-6, developed by Beijing Zhongxinchuang Technology Co., Ltd., is a high-tech, intelligent, stand-alone time server based on the NTP/SNTP protocols. DNTS-6 obtains standard clock signal information from GPS geostationary satellites and transmits this information over the network, enabling devices that require time signals—such as computers and controllers—to synchronize with the standard clock. Standard clock information is transmitted via the TCP/IP network, and DNTS-6 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, DNTS-6 supports the broadcast mode of the SNTP protocol.

Network Protocol:	NTP v1, v2, v3, and v4 (RFC 1119 and RFC 1305), SNTP (RFC 2030), MD5 Authentication (RFC 1321), Telnet (RFC 854), UDP NTP Unicast, Broadcast, Multicast, Autokey, TIME (RFC 868), FTP (RFC 959), DAYTIME (RFC 867), DHCP (RFC 2131)
	HTTP, SNMP v1 and v2, MIB II (RFC 1213), RSA asymmetric encryption
	IPV4
NTP Server Performance:	GPS/BD clock reference mode, Tier‑1 network time server, internal synchronization accuracy of 1 µs.
	User terminal synchronization timing accuracy: 0.5–2 ms (typical value on a local area network)
	User capacity: Supports thousands of clients.
	NTP request rate: 2,000 requests per second (per network port)
	Supports 50 log entries (per single network port)
GPS/BD receiver:	50-channel timing‑grade GPS/BD receiver, with options for single‑GPS, single‑BD, or GPS/BD dual‑mode operation.
	UTC synchronization accuracy: 30 ns (RMS)
	Receives L1 C/A code signal at 1575.42 MHz
	Tracking and lock‑on sensitivity can reach −160 dBm.
