Item is new old stock - never deployed but kept aside as a spare for a while.  Item ships in plain packaging.  No rack ears, cables or accessories other than the antenna are included.

This item has been tested by connecting to a GPS antenna - it achieves sync within the expected interval and the correct time/date shows on the integral LCD display panel.  The correct date was displayed in my testing (so the Lithium memory back up battery is most likely still good therefore).   If in your testing it shows the wrong date then this can be corrected via the procedure documented here.

A new basic antenna is included to get you started with your testing.   The test antenna needs to have a full unobstructed view of the sky to achieve lock, so you may need to put the whole ensemble outside (on a good weather day).  For a permanent installation an external antenna is highly recommended and I have some related hardware also listed on eBay.

TrueTime’s NTS-100i offers the total solution for enterprise-wide time synchronization over the network. The NTS-100i acquires precise time from GPS and distributes the time over the network using the Network Time Protocol (NTP). The NTS-100i can synchronize client computers typically to 1 millisecond. By installing the NTS-100i within your network firewall, you can ensure high reliability and security in delivering precise time.

The NTS-100i network time server is an essential resource for today’s enterprise network. Keeping accurate time on computers across the network is critical in many applications, including file timestamping, database transactions, e-commerce, and network security. Computer clock synchronization using the NTS-100i and ethernet time clients is an automatic function that eliminates operator errors or delinquency in manually setting the time. Because you can synchronize the NTS-100i to the GPS satellite system, precise network synchronization is available across the globe.

NTS-100i units deployed across widely separated local networks maintain synchronization across an organization without requiring time transfer between them. For easy remote access and control of the NTS-100i, you can use a standard web browser such as Netscape or IE Explorer. The intuitive graphical user interface is ideal for quickly checking a wide range of status functions and swiftly making any adjustment necessary. In addition to the browser interface, the NTS-100i supports Telnet, SNMP, DHCP, MD5, and RS-232 interfaces. Status and control functions are available via Telnet. The SNMP with MIB II support offers a standard interface for status information.

Password protection maintains secure remote access to the unit, and MD5 security protocol can authenticate NTP client-server communication.

The NTS-100i is a full-featured, Stratum 1 network time server easily configured into a network. The rear panel supports 10Base-T connectors for timing and control functions; a 9-pin RS-232 connector; and two BNC output connectors for IRIG-B and 1 PPS outputs. A separate BNC connector is provided for Alarm outputs. The NTS-100i also includes a front-panel keypad, a display, and a status/alarm LED. GPS-equipped units include an integrated GPS receiver, an antenna for external mounting, and a cable. Bringing the NTS-100i on-line requires only entering the IP address, subnet mask and gateway address.

 

The receiver locks onto a GPS signal when the antenna has a reasonable view of the sky.  The status indicator then turns to flashing green - indicating that time has been successfully acquired with no problems detected.

The location's Latitude, Longitude and Elevation are obtained accurately.
