NTP80 plus
Triple-Port Network Time Server
The NTP80plus provides highly accurate yet economic time distribution over local area networks (LAN) using Network Time Protocol (NTP), the industry-standard means of time distribution over discrete networks.
Features
- Economic triple-port stratum 1 Network Time Server
- Can act as both host and server in peer-to-peer mode
- Capable of synchronising up to 3 discrete networks independently
- Client system accuracy to within 50 μs*
- Precision timing circuits ensure stability in event of synchronisation signal interruption.
- Con guration and alarm reporting capabilities using Simple Network Management Protocol (SNMP)
- 1pps output
- Supports up to 1500 clients
Input Synchronisation Options
- Satellite (GPS, GPS/GLONASS or GPS/BEIDOU) via Active Antenna or Long Distance Antenna System
- Analogue timecode, e.g. IRIG-B, AFNOR NFS-87500 (see over for full list)
- NTP (Peer-to-Peer)
- LF (MSF, DCF-77, etc)
Applications
The NTP80plus provides a cost-e ective way of providing time from a trusted source, which is critical in many organisations such as airports, railways, nancial institutions, telecommunications companies, etc.
Enterprise/Corporate Networks
Any business using devices on a network can bene t from using the NTP80plus - not only can it use a selection of highly accurate, trusted time sources, it is easily integrated into internal systems thus eliminating network security issues that arise from using an external time source e.g. from the internet.
Rail
The ability to operate in peer-to-peer mode means that the NTP80plus is especially useful as a sub-master clock in rail applications.
Key Benefits:
- Accurate & reliable time data from a trusted source
- Control over configuration via web browser
- Synchronisation between users - eradicates discrepancies
- System time stamping (e.g. for e-commerce transactions, e-mail sent & receive, etc) is highly accurate
- Automatic systems procedures, such as backups, occur at the correct time and in the correct order
Connections The unit provides three discrete RJ45 connections to separate 10/100BASE-T networks. The synchronisation source input is connected via a 50 BNC socket. 1pps output is also supplied on a BNC connector (female) at a level of 5 volts A RS232/RS422/RS485 serial port for configuration and as optional serial time code output Interface Standards Network Configuration Configuration of network parameters including IP Address, Sub-net Mask, Gateway Address, SNMP Trap Address, and SNMP Read/Write community names is via web-browser. All such details are stored in non-volatile memory. User specific network parameters can be factory-configured upon request. Same user port available for upgrade of flash code for newer versions or additional options.
