Powerful and Reliable

The T100 utilizes a powerful Linux based industrial processor module, which also has very low power consumption. The device runs very cool, no cooling fans are required, providing exceptional reliability.

NTP and SNTP Protocols

The latest NTPv4 protocol is used by the T100, which is backwards compatible with previous versions of NTP. It can synchronize any NTP or SNTP compatible system, including Windows, Linux, CCTV, DVR and network devices such as switches and routers.

Unique in such a low cost device, the T100 has the processing power to serve in excess of 2 million clients at the default NTP polling frequency.

Additional Network Protocols

Future-proofing is achieved by the implementation of both IPv4 and IPv6 protocols. The device also supports: HTTPS, HTTP, SSH, SCP, SNMP v1/v2c/v3, SFTP, FTP, DHCP, DHCPv6.

High Accuracy Timing

When locked to GPS signals, the T100 GPS receiver can provide timing pulses to within 15 nanoseconds. The NTP daemon utilizes timing information from the receiver to synchronize within 3 microseconds of UTC.

Flexible Installation Options

The T100 features a cutting-edge GPS timing receiver that can continue to provide timing information in very challenging environments. The receiver can operate down to a single satellite in view, making window antenna location possible. The device also operates in a high-sensitivity mode, so that in many locations, indoor operation is possible. These features can provide installation cost savings compared to traditional roof-mounted antenna systems.

The T-3040 GPS antenna supplied with the T100 is entirely weather-proof and can be roof-mounted, to provide a reliable, consistent signal lock.

T-3040 High-Gain GPS Antenna

Supplied with the T100 is the high-gain T-3040 GPS antenna. It covers the GPS L1 frequency band and provides excellent circular polarized signal reception, out-of-band signal rejection and multipath rejection. The antenna provides great signal-to-noise ratio and consistent response in all operating temperatures. Additionally, with 40dB gain, long cable runs can be easily accommodated.

The antenna is housed in a through-hole mount, weather-proof enclosure for permanent installation. It can be used for indoor or outdoor applications.

Also supplied with the T100 is the MT4-GPS antenna mount. The mount provides secure antenna fixing to a flat surface, wall or mast.
