GPS RS485 Time Source Module
GPS-TS-485
The GPS-TS-485 is a high-accuracy GPS-based time source module producing NMEA and 1PPS outputs through RS485.
Product Description
The GPS-TS-485 is a GPS-based time source module designed for time and clock applications requiring high accuracy. The exact UTC time is available through NMEA sentences, and precise synchronisation is achieved through the 1PPS (1 pulse-per-second) output. The NMEA sentences and 1PPS pulse are provided through two individual RS485 outputs. This allows the application requiring time input to be located at a distance away from the module.
Supply power and the two RS485 outputs are connected through a RJ45 connector. The module includes a built-in passive GPS antenna. An external active antenna may be connected using the SMA connector if higher signal availability or outdoor environment IP-rating is required.
