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

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
