Technical Specifications
RECEIVER: narrowband synchronous receiver with automatic gain control
bandwidth: approx. 40Hz
FIELD SRENGTH: indicated by LED
DISPLAY: LC-Display, 4 x 16 characters
TIMECODE
CHECK:
multiple software check of the incoming timecode
parity and consistency check over a period of two minutes
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.
RUNNING
ON XTAL:
RF distortions indicated by "Freil."-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 24h of synchonous operation)
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)
MANUAL
SET MODE:
Time and date can be set manually through a menu
OUTPUTS: minute and second slave line pulses (TTL level)
4 relay outputs; max. 50W load
INTERFACES: 2 independent interfaces (COM0 and COM1)
baudrate, framing, output mode and time zone are configurable
for each interface
COM0: 1 RS232 output, 1 RS232 input, 1 active current loop outputs
COM1: 1 RS232 output, 1 RS232 input
