1 | Open the Operation menu. |
2 | Set Operation to Normal.![]() The Operation function controls the operating mode of the SU90 system. Normal mode allows the SU90 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 SU90 transmissions into the water. If you choose Maximum, the SU90 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 SU90 system can handle the information from each ping, how fast it communicates with external peripherals, or how long time it
uses to save data.
