Introduction

Here's a compact GPS time receiver clock with integrated NTP server.

The unit has been refurbished with a new internal backup real time clock/Lithium battery module so that the unit will continue to keep time even when the GPS signal is unavailable. The date is supplied by the internal real time clock module so the unit is not vulnerable to week number roll-over issues.  The supplied test antenna is new.  For a permanent installation an external antenna is highly recommended as the unit will probably not operate reliably through a window. I usually have some suitable antennae listed. Contact me if you need a recommendation. This receiver does not have an internal web server for status reporting however all the control parameters are accessible via the serial port.

Full details may be obtained from the User Manual

The unit has been tested and confirmed to achieve a Green LED status signal. The results of various queries to the serial port are shown below.

Description

Share accurate time across your LAN or enterprise network with a NetClock/NTP – Network Time Provider. The NetClock/NTP uses NTP (Network Time Protocol) to synchronize the timeclock of computer clients or servers over your TCP/IP network.

The NetClock/NTP derives time from GPS satellites and automatically tracks up to eight satellites simultaneously. Time derived from the NetClock/NTP 10Base-T connection is traceable to NIST (National Institute of Standards and Technology) and USNO (US Naval Observatory).

The NetClock/NTP is ideally suited for delivering system-wide split-second timing for stock brokers, financial institutions, network security, e-commerce and B2B transactions.

In addition to the 10Base-T connection, this unique hybrid has the industry-standard NetClock RS-232 and RS-485 time code outputs for non-networked devices, like voice recorders, time and attendance systems, display clocks, alarm and video systems.

Spectracom NetClocks and accessories are the most dependable, high quality network time providers.
