1Introduction
The GPS 400 is a complete GPS sensor which includes an embedded 12 channel GPS
receiver and antenna. It is designed to withstand rugged operation and is waterproof to IEC
60529 IPX7, immersion in 1 meter of water for 30 minutes.
Installation is simple. All that is required is for the GPS 400 to have a clear view of the sky. It
can connect directly to either a PME GPS 0100 Network Time Serve or a ProTime GPS Clock.
Power for the GPS 400 is provided from either of these modules through a standard CAT 5
cable. Communications between the modules uses RS-485 signal levels. The cable can be up
to 1,000 Ft. in length.
1.1 Features
•12-channel GPS receiver tracks up to 12 satellites for fast, accurate, time and
position.
•Differential DGPS capability using real-time WAAS corrections yielding 3 to 5 meter
position accuracy.
•Compact, rugged design ideal for application with minimal space.
•Simple installation. No coax cable or power cable to run.
•User initialization not required.
•Highly accurate 1 pulse-per-second output.
•Waterproof design allows continuous exposure to the prevailing weather conditions
at most locations.
2Installation
The GPS 400 should be mounted with a clear view of the sky and as far away from electrical
machinery as possible. It can be mounted using a 1”-14 thread marine antenna mount. The
GPS 400 is supplied with a 10 ft. cable terminated in a standard RJ45 connector. An IP-67
rated in-line connector is supplied for installations that require addition cable length. Up to
1,000 ft. of additional CAT5 cable may be used to connect the GPS 400 to the PME GPS 0100
or ProTime GPS Clock. Shielded CAT5 is recommended for long runs in noisy environments.
