3. INPUT/OUTPUT SIGNAL
3.1 Inputs from Sensors
There are three input ports (SENSOR 1, 2 and 3) which are based on the IEC
61162-1/2. The protocol is RS422. If there is no HDT signal from a gyrocompass,
connect the gyrocompass signal (Synchro or step signal) to the “AD-10 IN” port
(D-sub 9 pins) of the transponder unit via the FURUNO A/D Converter AD-100 (See
page 16).
