This device serves as a reliable, cost-effective solution for organizations that require precise timekeeping across distributed environments, such as data centers, hospitals, and broadcast facilities.
- Accuracy & Independence: By utilizing a local GPS signal, the TM1000A eliminates reliance on internet-based time sources, which can be highly variable due to network jitter. It maintains a server time precision of better than 5ms plus network jitter.
- Capacity: The unit can support over 120,000 devices on a network with 15-minute update intervals.
- Network: 10/100 Mbps RJ45 port for local network connection.
- GPS: SMA female connector for the included active patch antenna (5m cable).
- Serial: DB9 port supporting RS-232C and TTL levels, outputting NMEA data strings and a 1PPS signal.
- Security Features: To protect against external threats, the server includes options to mask HTTP and NTP access only to the local subnet, providing a measure of security against unauthorized access and denial-of-service (DoS) attacks.
- Configuration: Users can manage the device via a standard web browser interface or a serial terminal program. It supports both IPv4 and IPv6 addressing.
