Defining the ping (transmission) modes
You can easily control how often the CS90 shall transmit acoustic energy (a ping) into the water. You can disable the transmission altogether, set it to operate as fast as possible, or select a time interval.
Context
Image
Once pinging is On, use Transmission Mode to choose how often the CS90 shall transmit (ping). Use it to control the behaviour of the transmissions (pinging).
•  Single Ping: The CS90 transmits (pings) only when you select the symbol on the right side of the button.
•  Interval: The CS90 transmits (pings) with a fixed time interval. Ping Interval permits you to choose the time (in milliseconds) between each transmission (ping).
•  Maximum: The CS90 transmits (pings) as frequent as possible.
Procedure
1 Open the Operation menu.
2 Set Operation to Normal.
3 Set Transmission Mode to Maximum.

•  Select the symbol on the right side of the button to start pinging.
•  Select the symbol on the left side the button to stop pinging.
•  Select the middle of the button to open it.
If you choose Maximum, the CS90 will transmit (ping) continuously and as often as possible. This gives you the maximum refresh rate. The time between each ping (the ping rate) depends mainly on the current range. In some systems, a low performance Processor Unit and/or a slow hard disk may reduce the ping rate. How fast your Processor Unit communicates with external peripherals may also have an effect on the ping rate.

4 Set Transmission Mode to Interval.
Specify the interval between each ping.
Select either side of the button to choose a value. Select the middle of the button to open it. If you have a keyboard connected to the CS90, you can type the requested value.
You can also change the value by selecting - and holding - the middle of the button, and move the cursor sideways. Drag the cursor sideways to increase or decrease the value. Release the mouse button when requested value is shown.

5 Set Transmission Mode to Single Ping.
The CS90 transmits (pings) only when you select the symbol on the right side of the button.
