Page 5: General Information
General information The satellite receiver clock GPS161AHS has been designed to provide an extremly precise time reference for the generation of serial time telegrams. The clock was developed for applications where conventional radio controlled clocks can´t meet the growing requirements in precision. High precision available 24 hours a day around the whole world is the main feature of the system which receives its information from the satellites of the Global Positioning System. -

Page 7: Gps161Ahs Features
GPS161AHS features The satellite controlled clock GPS161AHS is designed for mounting on a DIN rail. The front panel integrates two LED indicators, a hidden push button, a DSUB- and a BNC-connector. The receiver is connected to the antenna/converter unit by a 50 coaxial cable with length up to 300 m. -
Page 8: Installation
Installation Power supply The system GPS161AHS is designed for operation with an AC (100V to 240V, 47 Hz to 63 Hz) power supply. The integrated fuse is available at the front panel. To avoid potential differences between the signal ground of GPS161AHS and a post-connected unit installed on different DIN rails, the signal ground of the clock is insulated from the case. -
Page 9: Powering Up The System
Powering up the system If both, the antenna and the power supply have been connected, the system is ready to operate. About 10 seconds after power-up the receiver´s TCXO has warmed up and operates with the required accuracy. If the receiver finds valid almanac and epheme- ris data in its battery buffered memory and the receiver´s position has not changed significantly since its last operation the receiver can find out which satellites are in view now. -
Page 10: Bsl Key
BSL Key Whenever the on-board software must be upgraded or modified, the new firmware can be downloaded to the internal flash memory using the serial port COM0. There is no need to open the metal case and insert a new EPROM. If the BSL key behind the front panel is pressed during operation, a bootstrap- loader is actived and waits for instructions from the serial port COM0. -
Page 11: Replacing The Lithium Battery
Replacing the lithium battery The life time of the lithium battery on the board is at least 10 years. If the need arises to replace the battery, the following should be noted: ATTENTION! Danger of explosion in case of inadequate replacement of the lithium battery. -
