Ping function
The purpose of the Ping function is to enable or disable the acoustic transmissions into the water. Such transmissions are often referred to as "pinging".
Prerequisites
The Ping function is only available when the EK80 system operates in Normal mode.
How to open
This function is opened from the Operation menu.
Description
The transmission ("pinging") can be turned on or off. Select the middle of the button to see the choices, or either side to enable or disable transmission. The ping symbol on the right side of the button is also used to transmit single pings.
Once pinging is On, use Ping Mode to choose how often the EK80 system shall transmit.
Details
On
The EK80 "pings" (transmits) energy into the water. The ping mode if controlled by the Ping Mode and Ping Interval settings.
Off
The EK80 does not "ping". No transmissions take place. When Ping is set to Off, the EK80 stops with the current echogram shown.
Tip
If you want to establish a passive system (transmission switched off, but normal reception), use the functionality offered
by the Normal Operation dialog box.
If you wish to investigate the ambient noise, choose Passive mode in the Normal Operation dialog box. Any noise or disturbance in the water - within the transducer's frequency range - will then be detected and shown. This feature will for example be able to pick up disturbances from other hydroacoustic systems on your own vessel, or on other
vessels in the vicinity.
