Product Overview
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, backed by a 5-year warranty and a responsive, knowledgeable sales and technical support staff.

| RS-232 and RS-485 ports operate independently and can be programmed during setup to output different time code data formats using baud rates between 1200 and 9600, 8N1. RS-232 and RS-485 ports can follow UTC or any Time Zone. Alarm output, contact closure, for “Loss of Time Sync”. |
| Inputs / Connectors | RS-232 Setup Interface: DB9 female Setup interface port is used to change factory default settings for all output and alarm ports. The port is also used to recall report logs and upgrade software in FLASH memory. The port works at 9600 baud, 8N1, and can be accessed with a PC terminal emulator.
