Introduction to the keypad

The keypad is used for direct user interface with the PI54

system, and allows you to control the functionality. Note that the

majority of the buttons are mainly used only during echo

sounder operations, and that some of them will only work when

they are enabled by a specific function.

EVENT: This button places a vertical marker on the

echo sounder depth display to identify an event.

MENU: This button turns the menu bar on and off. It

will also allow you to exit dialogues without applying

any changes.

ENT (Enter): This button allows you to apply the

changes you have made in a setup dialogue, or to select

a function from the menu. This button will also give

you access to the “Echo quick menu”, and it will open

the setup dialogue for the presentation in the active

window.

Selector pad: Use this button to navigate through

menus and dialogues. It moves the cursor horizontally

by pressing it on the left or right side, and vertically by

pressing it on its top or bottom.

-/+: These two button are used to select between

available values, scales and ranges. (-) reduces and (+)

increases the graduation.

GAIN: The two gain buttons are used to adjust the

receiver gain on the echo sounder.

STND (Standard): This button will activate an echo sounder

window in Standard mode. If you press this button while an

other window is active, the display switches to an echo sounder

page. If one of your other pages already contains a full screen

echo sounder, the PI54 will automatically change to this page,

and you must press the PAGE button to return to your previous

page. If you do not have an echo sounder presentation among

your four presentation pages, the current presentation will be

replaced by the echo sounder presentation.

ADJ (Adjust): This button provides a direct access to the setup

parameters for the data in the active window. To exit the setup

without making changes, press the MENU button.

VRM (Variable Range Marker): This button provides a

horizontal marker line on the echo sounder display. Use the

selector pad to alter the depth of the marker. The button will

only work if you have an echo sounder presentation on the

current page.
