1. GENERAL

1.1 Outline

The Interswitch Kit enables all possible interconnections between two or more radar display units and
two or more scanner units installed on the bridge of a ship that have different characteristics.
The NQE-3015N Interswitch Kit is used for the JMA-9800 series radar system and it is capable of
switching over interconnections between three display units and three transmitter-receiver/scanner units
(hereinafter called "MTR").

1.2 Interswitch Construction

The Interswitch Kit is incorporated in the display unit. (Option)
The number of combined display units and MTRs according to the interswitch kit is different between
the 2-units system and the 3-units system.
The distinction between the 2-units system and the 3-units system is determined by the internal settings.
The pattern switchover operations can be exercised simply and quickly according to the menus
displayed on the display unit. The interswitch patterns as shown below are displayed at the upper left of
the radar display. (The position filled on the mark indicates the position of the display unit currently
operated.)
