FEATURES
• NTP Reference for Ethernet LANs in selfcontained box
• NTP time synchronized to an internal precision oven controlled crystal oscillator
(OXCO) for typical stability of 1 ppb/day (< 7 sec/year) after 30 days of aging.
• NTP query (unicast), multicast, or broadcast modes
• Assignable network configuration
• Telnet or serial interface – Discovery Tools included
• Rack mountable in our RM4 or standalone
• 115/220 VAC or 9-28 VDC operation
SPECIFICATIONS
NTP Time Accuracy
• After initial input of time setting and 30 days aging
the NTP100-OSC will typically maintain stability of
1ppb/day (<19mS/day) or <7 sec/year using an
internal high precision OCXO (oven controlled
crystal oscillator) and battery backed real-time
clock circuit.
Outputs
• NTP reference for query (unicast), multicast, or
broadcast mode – user definable
Rack Mount
• Optional rack mount kit is available - RM4
Connectors
• RJ45, 10/100 MB/sec Ethernet connection
• DC input - 2 mm jack

Case
• Cover - off-white aluminum
• Front/rear panel - clear anodized aluminum
Setup and Control Software
• Supports DHCP/BOOTP for automatic acquisition
of network address, nameservers, and time server
configuration.
• Provides dynamic configuration for networking
parameters.
• Configure clocks through provided network
WinDiscovery tool or TELNET
• Network discovery tool provides automatic
discovery of NTP clocks attached to network
without changing PC’s networking configuration.
• Configuration is saved to non-volatile memory and
survives power losses.
• Encrypted network messages prevent
unauthorized tampering of clock configuration.
Power Supply
• 9-28VDC input. Includes an external 12 VDC wall
mount power supply with locking DC plug, UL & CE
listed
• 115/220, 50/60 Hz, < 10 W Power AC Input
• Supplied with your choice of US, Euro, British or
AUS/NZ plug - others optionally available
Operating Temperature and Humidity
• Temperature: 0 to +40°C (40 to 50°C ±1 min/year)
• Humidity: Up to 90% (non-condensing at 25°C)
