Item is lightly used in very good cosmetic condition. It has been tested to confirm that it works as it should - see below for the console port output obtained during testing of the actual item for sale. The time and date are correctly obtained from the GPS system. The network connection at the rear is via an AUI port. AUI to 10Base-T RJ45 converters are cheap and readily available - see here. The unit achieves sync via the GPS satellite constellation. A basic 5V test antenna is included to get you started - the antenna needs a full view of the sky to achieve reliable time sync. For a permanent installation an external antenna is highly recommended and the unit will probably not operate reliably through a window. I usually have some suitable antennae listed. Contact me if you need a recommendation.

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.
