LC2750 Time Server Overview

TimeTools new LC2750 RS232 Serial GPS time source provides computers and computer networks with a highly precise timing reference. The LC2750 provides a real breakthrough in price and performance. The compact device is housed in a rugged, aluminium enclosure, ideal for applications with space-saving requirements.

“The LC2750 provides a reliable, highly accurate, traceable, source of time inside your firewall”.

Indoor Operation
The LC2750 incorporates a highly sensitive GPS timing receiver that can often operate with an indoor located antenna. This reduces installation costs, as a roof mounted GPS antenna is often not required. Additionally, surge suppression to protect from potential lightning strikes is not required with an indoor antenna. Of course, the GPS antenna is completely weather-proof and can still be mounted outdoors if you wish.

Single Satellite Operation
Over-determined clock technology allows the LC2750 to provide accurate timing information while only a single satellite is in view.

High Precision
Timing information to +/- 60 nanoseconds can be provided via a RS232 serial interface. Typically, an 800MHz Pentium PC running Linux can be synchronised to within 1 microsecond of UTC.

5-Year Warranty
The LC2750 GPS Timing Receiver is a low-power convection cooled device with no moving parts, aiding long-term reliability. Our confidence in the reliability of the device is reflected in the provision of an industry leading 5-year warranty.

Software Drivers
Software drivers are available for most operating systems including Microsoft Windows and LINUX \ UNIX. Network Time Protocol (NTP) drivers are available for Windows to provide network time synchronisation. LINUX \ UNIX drivers are provided as source code as a NTP reference clock driver for the standard NTP distribution.
