Page 5: General Information
General information The satellite receiver clock GPS163TDHS has been designed to provide an extremly precise time reference for the generation of programmable pulses and IRIG/AFNOR- codes. The clock has been 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: Features Of Gps163Tdhs
Features of GPS163TDHS The GPS163TDHS is designed for mounting on a DIN rail. The front panel integrates five LED indicators, a hidden push button, an eight-pole terminal block, three female D- SUB-9- and three BNC-connectors. The receiver is connected to the antenna/converter unit by a 50 -coaxial cable with length up to 250 m (if using RG58-cable). -
Page 8: Pulse Outputs
Pulse outputs The pulse generator of the satellite controlled clock GPS163TDHS containes three independant channels and is able to generate a multitude of different pulses, which are configured with the software GPSMON32. The active state of each channel is invertible, the pulse duration settable between 10 msec and 10 sec in steps of 10 msec. -
Page 9: Dcf77 Emulation
DCF77 emulation The GPS163TDHS satellite controlled clock generates time marks which are compa- tible 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 at a BNC- connector in the front panel. -
Page 10: Asynchronous Serial Ports
Asynchronous serial ports Two asynchronous serial interfaces (RS-232) called COM0 and COM1 are available to the user. In the default mode of operation, the serial outputs are disabled until the receiver has synchronized after power-up. However, the system can be configured to enable those outputs immediately after power-up. -
Page 11: Available Time Codes
Available time codes The timecode generator of the module GPS163TDHS is able to generate the time- codes shown below. The modulated codes (IRIG B122/B123, AFNOR, IEEE1344) are available via the BNC-connector, the unmodulated codes (IRIG B002/B003 and IEEE1344) via a DSUB connector in the front panel. The unmodulated codes are available as a transistor output with internal pull up (1 k to +5V), with TTL-level into 50... -

Page 15: Installation
Installation Power supply The module GPS163TDHS is designed for operation with a DC (19 V to 72 V, DC- insulation 1.5 kV) power supply. The voltage feed is done by using terminal blocks in the frontpanel of the clock and should have low resistance to minimize spurious emission (EMI). -
Page 16: 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-backed 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 18: 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 19: Assignment Of The Dsub Connectors
Assignment of the DSUB connectors The serial ports COM0 and COM1 and the unmodulated timecodes are available at female D-SUB-9 connectors in the frontpanel. The RS-232 interfaces can be connec- ted to a computer by using a standard modem cable. TxD describes the sending, RxD the receiving line of GPS163TDHS. -
