Technical Specificatins
RECEIVER: narrowband straight receiver with automatic gain control
bandwidth: approx. 40Hz
reception via external ferrite antenna
DISPLAY: 14-digit, 13/14mm high numeric/alphanumeric LED display for
time, date and day-of-week, variable brightness
modulation, RF amplitude and free running indicated by LEDs
TIMECODE
CHECK:
multiple software check of the incoming timecode
parity and consistency check over a period of two minutes
RUNNING
ON XTAL:
RF distortions indicated by LED and a status character in the
serial output string
Without RF signal the clock runs on XTAL with an accuracy of
10
-6
(after 24 hours of synchr. operation), indicated by LED
BUFFERING: In case of supply voltage failure the on-board RTC keeps the
time based on XTAL for more than 150 hours (buffer capacitor)
optional lithium backup battery (life time: 10 years)
RELIABILITY
OF OPERATION: A software watchdog lets the microprocessor recover from
malfunction. A power-fail comparator resets the microproces-
sor if the supply voltage drops below a specified threshold.
INTERFACE: one serial port, RS232 or 20mA current loop (input active,
output passive)
Baudrate:
600 ... 19200 baud
Framing: 7e2 or 8n1
OUTPUT MODE : configurable by DIL switches
once per second, once per minute or only on request ("
?
")
TIME ZONE: configurable by DIL switches
MEZ/MESZ=CET/CEST, UTC
OUTPUT STRING: see "Format of the Meinberg Standard Time String"
