Description
RS232 interface via 9 pin SUB-D female connector.Pulse per second and pulse per minute. These pulses are
accessable via the ten pole screw terminal.
RS232 Output
An asynchronous serial port can be used to transmit information on date and time to other devices. The clock is
configured to send time messages automatically with 9600 baud and with a framing of 7E2 once per second.
Pulse Output
After DCF77 synchronization, a pulse per minute and a pulse per second, with a pulse duration of 0.2 seconds, will be
switched on. The generation of the pulses will be maintain for 12 hours if the DCF77 receipt is disturbed. Thereafter the
pulses will be deactivated.
Housing
The receiver module is mounted in a plastic housing for 35mm DIN mounting rails. Two status LEDs (for modulation and
free-running mode), the BNC antenna connector and a D-SUB9 connector for the serial RS232 interface are integrated
in the front side of the housing.
Operating Voltage
The system requires an operating voltage of 19...72V/DC witch is applied via two contacts of the integrated screw
terminal. The receiver is DC isolated due to an internal DCDC converter, the isolation voltage is 1,5KV DC.
Characteristics
Type of receiver
Narrowband straight receiver with automatic gain control, Bandwidth: approx. 40Hz
Type of antenna
Scope of supply includes an active ferrite antenna AI01 and 5m of RG174 coaxial cable
with BNC male connectors. Optional: AW02 with RG58, other length of cable
Status info
Modulation visualized by LED. Free running state visualized by LED after switching to
free running quartz clock mode
