Optional 1U rackmount for mounting one,two or three units (Rack mount kit comes with shelf, screws and 2 blanks. Each kit can take one, two or three LeoNTP 1200 units)

Optional DIN Rail Mounting Kit (See related items)

Unit can sustain 100Mbps (> 100,000 NTP Packets a second) 

Traditional Master Clocks either have high performance or low cost. With LeoNTP Time Server 1200 you can have both in the same package.

Key Features

• True Stratum 1 NTP Compatible Master Clock / Time Server.
• Can serve tens of thousands of clients.
• Very cost effective
• Supports NTP/SNTP
• Front TFT Display for time display and configuration

Frequently Asked Questions:

Q/ Is this unit based on Linux and NTP ?
A/ No the hardware and code running it are completely propriety and don’t use any source code from Linux or NTP. This is done to ensure maximum performance with no overheads and security issues.

Q/ Can I configure it via HTTP/Telnet ?
A/ No. Running a web server on this device although entirely possible would reduce the performance of the unit. Therefore we took the decision to just do configuration via the front panel.

Q/ The performance figures look too good to be true at the price
A/ The performance figures are the result of a focused determination to get the best performance out of the hardware. By not using off the shelf hardware and software we have no overheads or compromises. Try it yourself using Miroslav Lichvar's ntpperf tool. It only starts to drop when the 100Mb interface is maxed out:

nevis@test:~/ntpperf$ sudo ./ntpperf -i enp5s0 -m 70:B3:D5:E3:D0:04 -d 172.16.1.72 -s 172.16.1.0/16 -B

Q/ Can the unit be firmware updated?
A/ Yes via USB into a Windows PC or Mac. Updates take about 5 seconds to apply.

Q/ Is the BNC output compatible with the Airspy
A/ Yes. Set the BNC output to 10Mhz. Connect the unit to your Airspy via the optional BNC to MCX cable and power the Airspy on.

Q/ Can the unit display my local time ?
A/ Yes. Press the button on the clock screen and use the knob to select your time zone.

Q/ Whats the maximum length of coax to the antenna ?
A/ This depends on the antenna and coax. We've tested our timing antenna (comes with 10 meters of coax) with a 20 meter extension and it works fine. The unit is POE so it may be easier to run a network cable closer to the antenna and install the unit there.

Q/ Does the unit support IPv6
A/ From firmware 2.06 IPv6 via SLAAC or Static allocation is supported (DHCPv6 isn't supported)

Q/ What happens on loss of GPS Signal
A/ The unit enters failover mode which uses internal compensation to maintain the accuracy of the timing to 1-4ms typically over 24 hours. After 24 hours with no GPS signal the unit reverts to being a Stratum 16 time source.

Q/ Leap Second Support
A/ The unit has leap second support and a count down timer to the next leap second insertion.
