4.7.3 Independent connection
This connection method allows the monitoring of an Antenna unit with two Display units as with the
parallel connection, however only the master Display unit can control the antenna and the slave
Display unit cannot control it.
For example, when the captain operates the master Display unit and does not want any changing
of pulse length from the other Display unit without permission, this connection is used. However,
as the slave Display unit cannot control an Antenna unit, its range setting should be set up in
accordance with the pulse length used for the range of master Display unit to obtain a correct
picture.
Functions such as a range, ATA, AIS, gain, anti-sea clutter, anti-rain clutter, and marker can be
operated independently for the slave Display unit.
The master and slave role can be exchanged in Figure 4.7.
Setting example
(1) Press [MENU] key of the Display unit to be master, select using joystick as follows: OPTION
=> INTERSWITCH => INDEPENDENT MASTER and then highlight it.
(2) Press [ENTER] key to save. When one Display unit is set by the inter-switch connection as
independent master, set the other Display unit to independent save manually because it
does not set independent slave automatically. Also, any input data from an external sensor
such as heading, speed, latitude/longitude will be shared by both Display units. The Display
unit without external sensor may offset the bearing of picture and heading.
Setting method
Press [MENU] key, select OPTION => ECHO OFFSET => VALUE using a joystick highlight the
last digit while observing the picture.
(1) Press [ENTER] to save.
(2) Offsetting of heading is performed in the same way.
