1.2.4 Colour printer echogram
The printer is able to generate more information than the display. Most
elements are controlled by parameters found in the Printer Menu.
The EY 500 may be interfaced to different colour printers. The graphic
resolution is 720 dots with 12 different colours ranging from light grey to brown.
The black colour is mainly used for text and separation lines.
The echogram paper speed is determined by the setting of the echogram speed
parameter (Printer Menu) and the current ping interval (Operation Menu). The
echogram colour presentation is mainly influenced by the colour minimum and
the selected TVG type (PRINTER/Echogram Menu). If the bottom range is
enabled, 20% of the main echogram is overwritten by this bottom-referenced
echogram.
The echogram may include several lines and text strings which are enabled by
the corresponding parameters in the menu system.
In figure 3, arrows and numbers from (1) to (15) point out the different topics
explained below:
1)
Layer lines.
As for display echogram, except that layer lines are switched ON/OFF in
the PRINTER/Echogram Menu.
2)
Super layer.
As for display echogram.
(3)
Nautical mile marker,
MODE in the Log Menu must be set to SPEED and NAUTICAL MILE
MARKER in the Printer Menu must be set to ON. At detection of a new nautical
mile, a black vertical line accompanied with text will be written across the
echogram paper. The text string shows the log distance in nautical miles plus
the NM indicator for easy recognition of the nautical mile data.
