The
Operation
function controls the operating mode of the ST90 system. Normal
mode allows the ST90 system to transmit ("ping") through the water, and to receive
the echoes.
3 Set
Transmission Mode
to Maximum .
The
Transmission Mode
function enables or disables the ST90 transmissions into the
water. If you choose Maximum , the ST90 system will transmit (ping) continuously and
as often as possible. This gives you the maximum refresh rate.
The ping rate is normally limited by the maximum range settings. It also depends on
hardware limitations. This may be, for example, how fast your ST90 system can handle
the information from each ping, how fast it communicates with external peripherals, or
how long time it uses to save data.
