Meinberg Radio Clocks Auf der Landwehr 22 31812 Bad Pyrmont, Germany Phone: +49 (5281) 9309-0 Fax: +49 (5281) 9309-30 http://www.meinberg.de [email protected] UA509: DCF77 Radio Clock DCF77 Radio Clock UA509 with 2 serial interfaces, pulses per minute and per second, and a 2.5mm LED Display. Key Features - Direct conversion Quadrature Receiver - Pulses per second and per minute - 20mA input/output circuits - 2,5mm LED-display - 2 RS232 interfaces - Receiver status LEDs - Buffered hardware clock - Flash-EPROM with bootstrap loader rev 2006.0615.1425 Page 1/3 ua509 Description The hardware of UA509 is a 100mm x 160mm microprocessor board. The 20mm wide front panel contains an 8-digit LED display (2.5mm), three LED indicators and a time/date switch. The receiver is connected to the external ferrite antenna AI01 that is included in the sope of supply by the 5 meter 50 ohm coaxial cable (other lengths available). The radio controlled clock UA509 has been designed for applications where two independent serial interfaces are needed. The UA509 contains a flash EPROM with bootstrap loader that allows to upload a new firmware via the serial interface without removal of the clock. Characteristics Type of receiver Narrowband DCF77 quadrature receiver with automatic gain control, bandwidth: approx. 20Hz Display 8 digit 7-segment LED display (2.5mm) for time or date (switch-selectable) optional: 20HP (100mm) wide front panel with 10mm height 7-segment LED display Status info Modulation and field strength visualized by LEDs Free running state visualized by LED after switching to free running quartz clock mode Synchronization time 2-3 minutes after correct DCF77 signal reception Accuracy free run Accuracy of the quartz base after min. -
