Setup![]() Connect the DC power supply, Ethernet cable, and antenna to the back. Using the PPS output connectorIf you would like to use the PPS output pins, please see the docs at https://centerclick.com/ntp/docs/pps_output for instructions for proper use. Location and antenna placementThe NTP200/NTP250 and power supply are not watertight and should only be used indoors or a user-supplied watertight enclosure. The included GPS antenna is water-resistant, features a built-in magnet and a 10ft cord. In most cases, the GPS antenna can lock to satellites from indoor environments. If you would like to purchase a waterproof outdoor antenna see the online docs for some recommendations. First power upPower backup for rapid boot-ups is implemented using a supercapacitor. On a cold boot where the supercap is discharged, it can take the GPS module 10-90 minutes to acquire lock. Please be patient. For the quickest acquisition, make sure the antenna puck isn't covered or inside loops of the antenna cord and place it on top of a piece of sheet metal to provide a good RF ground plane. Connecting the NetworkBoth IPv4 and IPv6 are supported and, by default, DHCPv4 and DHCPv6/Autoconf6 are used to obtain network addresses automatically. If you would like to use static addressing, this can be setup using the USB admin console. Monitoring and ConfigurationDetermine IP addressYou'll need to determine the IP address of the device to use the Web client, SSH, and configure your NTP clients. Unless you set a static IP using the USB admin console or on your DHCP server, you will need to either lookup the IP address using the MAC address printed on the top of the device in your router or simply connect to the USB admin console and use 'show net' to see network status. Web InterfaceThe web interface is read-only and provides monitoring status. By default, location data is displayed, however if you wish, you can turn on location data privacy for the HTTP interface using the admin console. USB admin consoleUse the Micro-B USB port for configuring the device or debugging when the network is offline. A serial console is presented over this USB port so you can use any terminal program and connect using 115200 baud N81 with no flow control. For driver and usage help see the online docs. Enabling SSH admin consoleIf you want to enable remote administration, you can enable SSH logins using the USB admin console. SSH logins are disabled by default. Both password and public key authentication are available. Configuring NTP Access ControlBy default all clients can synchronize with the device, however, you can use the admin console to configure IP/MASK sets that can have additional permissions or fewer permissions such as blocking. Software upgradeSoftware upgrades can be performed using the admin console. By default, the device will auto-install software updates but you can disable this by config if you wish. Configuring your NTP clientsSetup of your clientsYou will need to point your clients to use the devices using NTP. This can be done using a DHCP option, modifying /etc/ntp.conf on Linux devices, or using a GUI on Windows or MacOS. Broadcast/Multicast mode are also supported, but disabled by default. See the online docs for how to configure this. VerificationYou can verify if a client is using the device by viewing the NTP Clients link on the Web Interface which will list the IP of every client that has queried the device in the past 7 days.
