Page 3: Introduction
What is NTS-pico3? NTS-pico3 is next generation ultra miniature time server. It delivers time directly to network using NTP and PTP/IEEE1588 protocols. It is equipped with single 100/10Mbps Ethernet port working with IPv4/IPv6*. Unit is very small and natural air cooling. It has been designed for small industrial networks and it can operate 24/7. - Page 4 Referential UTC is drawn from GPS & Glonass via built-in GNSS receiver, using NMEA183 frame. NTS-pico3 can also act as an 1PPS frequency reference clock. It can distribute 1PPS using NTP or PTP IEE1588 protocol. It has also 1 SMA 1PPS output.

Installation Hardware The NTS-pico3 box on arrive includes: 1. NTS-pico3 miniature time server (pcs 1) 2. Power supply 12VDC/230VAC (pcs 1) 3. Outdoor active GNSS antenna w/ 30m coax H-155 and accessories (pcs 1) Options (not included in standard set): 4. -
Page 6: Antenna Mounting
The antenna is supplied with mounting clamps for attachment to a mounting pole, included too. Mast antenna suspension (H=0.5m) is not included but it is available as separate products from Elproma. Following figure shows an example of how mounting antenna might be achieved. -
Page 7: Additional Lightning Protection Considerations
NTS-pico3 unit. A second lightning arrestor should be installed near to the NTS-pico3 to further dissipate any remaining lightning energy. At the earth end please use multiple connection points if... - Page 8 Failure to do so is almost certain to result in destruction of NTS-pico3 and connected into it equipment in the event of the antenna receiving a near lightning strike.

Page 10: Powering Up
Powering up 1. Connect GNSS antenna to SMA connector at NTS-pico3 2. Connect Ethernet LAN cable to RJ45 connector 3. Plug-in DC power supply to power input and turn power ON Basic SETUP Go to your web browser and put IP address 192.168.1.234/255.255.255.0. - Page 11 IMPORTANT NOTE! For time synchronization purpose please do not use DHCP/DNS. You will need to keep SSH communication ON for GNSS signals tracing. SSH enable (ON) and password is necessary for tracing on-line GNSS signals...

Page 16: Running Ptp (Precision Time Protocol)
Running PTP (Precision Time Protocol) Switching on PTP enables PTP grandmaster daemon. PTP options: Transport layer L2 (Ethernet): PTP packets are encapsulated directly in Ethernet frames (IEEE 802.3 network transport) L4 (UDP): PTP packets are exchanged over UDP/IPv4 IP mode The option available for L4 (UDP) transport layer only. - Page 17 Delay is measured peer-to-peer. If transparent clocks are present in a network they need to support peer-delay mechanism (and be configured to enable it). SYNC interval (default 1) SYNC packet interval value must be in range -7..7 (recommended limits are -3...3). -4: 62.5ms (1/16 s) -3: 125ms (1/8 s) -2: 250ms (1/4 s)
- Page 18 To troubleshoot NTS-pico3 you need first to log into device console using serial cable or SSH. How to check if PTP is working? From NTS-pico3 console you can check if ptp process is running. If everything is fine, you shall get 1 in return:...
