Defining input signal
Both AR68 and AR77 have been designed to accept a variety of
digital input signals. When the cable is connected to the
repeater, it will automatically sense which digital signal that is
present. The following priority is used when defining the signal:
−
True heading (HDT)
−
Heading & Variation format (HDG)
−
Old Heading format (HDM)
If the signal is invalid or missing after 1 second, the repeater will
indicate this by flashing illumination and by rotating the dial
back and forth +/-35° around the last known heading.
If the defined input signal is lost, the power must be switched off
and on again. If the cable not is connected via an external
switch, the cable must be disconnecting and reconnected again
to define a new input signal.
