Page 5: General Information
General information The satellite receiver clocks GPS163DHS and GPS163AHS have been designed to provide an extremly precise time reference for the generation of programmable pulses. The variants are different in the power supply (DC or AC) only. The name GPS163xHS is used for both clocks in the following chapters therefore. -

Page 7: Gps163Xhs Features
GPS163xHS features The GPS163xHS is designed for mounting on a DIN rail. The front panel integrates five LED indicators, a hidden push button, an eight-pole terminal block, two DSUB- and two BNC-connectors. The receiver is connected to the antenna/converter unit by a 50 coaxial cable with length up to 250 m. -
Page 8: Asynchronous Serial Ports
The following modes can be configured for each channel independently: Timer mode: Three on- and off-times per day per channel programmable Cyclic mode: Generation of periodically repeated pulses. A cycle time of two seconds would generate a pulse at 0:00:00, 0:00:02, 0:00:04 etc. DCF77-Simulation mode: The corresponding output simulates the DCF77 time telegram. -
Page 9: Dcf77 Emulation
DCF77 emulation The GPS163xHS satellite controlled clock generates time marks which are compati- ble with the time marks spread by the German long wave transmitter DCF77. If configured in GPSMON32, these time marks are available as pulse outputs. In addition, an AM-modulated carrier frequency of 77.5kHz is available via a BNC- connector in the front panel. -
Page 10: Installation
Installation Power supply The variant GPS163DHS is designed for operation with a DC (19 V to 72 V, DC- insulation 1.5 kV), the type GPS163AHS with an AC (100V to 240V, 47 Hz to 63 Hz) power supply. The voltage feed is done through terminal blocks in the frontpanel of the clock and should have low resistance to minimize spurious emission (EMI). -
Page 11: 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. -

The front panel layout FAIL LED The FAIL LED is turned on whenever the receiver is not synchronous to the GPS-system. Oc 1 Lock Oc 2 Fail Oc 3 LOCK LED The LOCK LED is turned on if the re- ceiver has acquired at least four satelli- tes and has computed its position after power-up. -
Page 13: Bnc Connector Dcf Out
BNC connector DCF Out The insulated AM-modulated carrier frequency is available using this connector. BNC connector GPS Ant The antenna/converter unit is connected to the receiver circuit of the GPS163xHS through this connector. Assignment of the terminal block The pulse outputs are accessible through the terminal block in the front panel. In addition, the power supply is connected to GPS163DHS via two poles of this terminal block. -
Page 14: Assignment Of The Dsub Connectors
Assignment of the DSUB connectors The serial ports COM0 and COM1 are accessible via nine-pole DSUB connectors in the frontpanel. These RS-232 interfaces can be connected to a computer by using a standard modem cable. TxD describes the sending, RxD the receiving line of the GPS163xHS. -
