The front panel layout
FAIL LED
The FAIL LED is turned on whenever
the receiver is not synchronous to the
GPS-system.
LOCK LED
The LOCK LED is turned on if the
receiver has acquired at least four sa-
tellites and has computed its position
after power-up. In normal operation
the receiver position is updated conti-
nuously as long as at least four satelli-
tes can be received. When the receivers position is known and steady only, a single
satellite needs to be received for synchronization and generatation of output pulses.
OCx LEDs
The LEDs ‘OC1’, ‘OC2’ and ‘OC3’on the left of the terminal block are indicating the
status of the corresponding pulse output. A burning LED symbolizes the ON-state of
the optocoupler.
