Buffered Real Time Clock
In case of supply voltage failure the on-board real time clock keeps the time powered
by a backup capacitor for more than 150 hours. This capacitor does not need any
maintenance. Alternatively, the clock can be ordered with a lithium battery which has
a live time of at least 10 years guaranteed.
Display
The 14-digit LED display shows the time, date and day-of-week. The displays
brightness is variable in four levels by DIL switches. Modulation and RF amplitude
are indicated by LED. The brighness of this LED in the front panel depends on the
signal strength of the DCF77 carrier and it starts blinking exactly once per second,
corresponding to the time marks from DCF77. A decimal point behind the both second
digits indicates that the clock runs free without RF signal.
Serial Interface
The ANZ14 V3 provides a serial port that can be set up either as RS232 port or as
20mA current loop port. The input of the 20mA current loop is active, the output is
passive. The baudrate can be set between 600 baud and 19200 baud. If the 20mA
current loop output driver is used, the transmission speed should not exceed 9600
baud. The framing can be selected:
1 startbit / 7 databits / 1 even paritybit / 2 stopbits (7e2)
1 startbit / 8 databits / no paritybit / 1 stopbit (8n1)
The serial port can sent a time string periodic once per second/minute or only on
request by sending an ASCII '
?
'.
Power Supply
The integrated mains power supply provides the clock with a stabilized voltage of 5V.
The mains input (230V AC) is fused with T 0.2A / 250V. The DC versions (5V, 12V
and 24V) are fused with T 0.5A.
