The NTP1061 is a network time server that derives accurate time from satellites and serves it to your network. It is powered and networked over a single Ethernet cable using Power over Ethernet (PoE), and is designed for outdoor installation on a rooftop or pole with a clear view of the sky.

We recommend powering up and configuring the device indoors first, before mounting in its permanent location.

Note: Not included: the PoE switch or injector and the Cat5e/Cat6 Ethernet cable.

To mount on a pole, the NTP1061 can be used without its stand and screwed directly onto a pole (see below.)

Power over Ethernet (PoE) Compliance

This product is powered through its RJ45 Ethernet connector using standards-based Power over Ethernet (PoE). It is a low-power device (Class 1, under 2 W) but it requires IEEE-compliant 48-volt PoE power.

Choose a PoE switch or injector that is:

Rated to deliver 48 VDC nominal (44–57 VDC) at the port.
Compliant with IEEE 802.3af (PoE), 802.3at (PoE+), or 802.3bt (PoE++). Any of these will work. The device requires only the lowest power class, and all three standards are backward compatible.

Either a PoE-capable network switch (an "endspan") or a standalone PoE injector (a "midspan") may be used. With an injector, place it on the cable between your ordinary network switch and the device.

Warning: Avoid using "passive PoE" injectors or adapters. Passive PoE applies voltage to the cable without the IEEE detection handshake and is often a non-standard voltage (for example, 24 VDC). Using passive PoE may prevent the device from powering on and can damage it. Always use a 48-volt IEEE 802.3af/at/bt-compliant source.

Hardware and Cabling Requirements

Power: IEEE PoE-compliant source, 44–57 VDC, over the RJ45 connector. The NTP1061 consumes less than 2 watts.
Cabling: Category 5e (Cat5e) or Cat6 Ethernet cable from your company network to the NTP1061, up to 100 m (328 ft).
Mounting: Rooftop or pole mount, using the included stand or a compatible pole, with a clear view of the sky.
- Pole thread size: 1-inch-diameter American NPT

Initial Setup and Configuration

The simplest way to set up the NTP1061 is indoors, near a computer. The device can be moved outside after it is configured.

Connect power and network. Plug the PoE Ethernet cable into the NTP1061 and a network that has a DHCP server. The device will automatically obtain its IP settings.
Find the device. Connect to it via one of these methods:
- Visiting http://nbntp.local on a network/computer that supports mDNS/Bonjour
- Visiting https://discover.netburner.com from a computer on the same network
- Using our localdiscover utility, or one of the other methods listed on the localdiscover page.
If using a Discovery method, click on the Web link for your device. (The Config link is for advanced usage only.)
Set a static IP address. Since NTP clients generally expect to connect to a fixed IP address, we recommend that you configure the appropriate static IP Address, Mask, Gateway, and DNS Server values for your network.

Warning
Avoid lockout: double-check the static address, mask, and gateway before rebooting. If the static settings are wrong you may lose access and need to use localdiscover or hold down the reset button to recover.
Verify. Confirm the settings have taken effect. Upon save, the NTP1061 should redirect your web browser to the new IP address. Verify that the address bar looks correct. If your NTP1061 has sufficient satellite signal, set an NTP client to use the new IP address and synchronize its time to ensure proper functionality. If there's no signal, perform this step later.
Secure the device. Set a username and password through the NTP1061 web interface. This also secures the Advanced configuration page against malicious firmware upgrades, etc.
(Optional) Disable cloud reporting. To stop the device from reporting to discover.netburner.com, visit the Advanced configuration page and clear the address in the Discovery Report Url field of the Config > Sys > NetIf > Ethernet0 configuration section.

Note
The NTP1061 uses Ethernet0 only. All network configuration refers to the Ethernet0 interface, and Ethernet1 is unused.

Outdoor Installation

Note: The NTP1061's GPS/GNSS configuration and enclosure is intended for fixed installation on a building, not on moving vehicles or near water. For mobile or marine applications, please inquire with NetBurner.

Warning: The NTP1061's IP65 waterproof rating is effective when the device is installed as intended. Take care that all threads, seals, rubber plugs, and mounting hardware are securely installed. Ensure that the device is mounted firmly upright so that it cannot tip or collect rainwater. Protect the device from high-pressure water jets, and ensure it won't be submerged.

Preparation

Choose which method you'll use for mounting the NTP1061. You may use the included stand for rooftops and flat surfaces, or provide your own compatibly-threaded pole.
The device must have a clear view of the sky to receive satellite signals. Avoid locations obstructed by roofs, walls, foliage, metallic coatings, or other structures.
Plan your installation, set up the device on your network, and test that all parts fit beforehand.
Route the Cat5e/Cat6 cable from the location to your PoE switch or injector, keeping within the 100 m (328 ft) cable length limit.

Installing

1. Unscrew the bottom ring. If mounting on your own pole, also unscrew the included stand.

2. Route the Ethernet cable through all mounting hardware, including the bottom thread and bottom ring of the NTP1061.

3. Tighten all mounting hardware and connect the Ethernet cable to the NTP1061. If using the included stand, insert the rubber plug on the bottom. If mounting on your own pole, we suggest plugging the pole with caulk to reduce moisture and insect ingress.

4. Fit the NTP1061 on top of the mounting hardware and secure it by tightening the bottom ring.

Troubleshooting

"Time not yet valid": device does not yet have GPS lock; ensure it has a clear view of the sky and wait a few minutes.
Cannot reach the device after changing IP: use a Discovery method (see Find the device above) to find the new address; or Factory Reset the configuration using a method above.
HTTPS certificate warning: the auto-generated certificate is self-signed; either accept the exception in your browser or upload a trusted certificate
Configuration page access is denied: Factory Reset to clear the password
Device not responding: short-press the reset button to reboot; if unresponsive, Factory Reset

Physical Factory Reset

If you lose access to your NTP1061 or otherwise need to reset its configuration, unscrew the top lid and hold the reset button for 5 seconds. The device's LED is solid during normal operation, blinks once upon successful boot, and turns off during reset. A short button press reboots the device.

Note that a full successful boot includes getting GPS signal, generating an SSL certificate, and rebooting, so the device may be working even if the LED is off.
