The ST90 system transmits (pings) as frequent as possible. The time between each
ping (the
ping rate ) depends mainly on the current range. How fast your computer
communicates with external peripherals may also have an effect on the ping rate.
Ping Interval
The
Ping Interval
function permits you to choose the time (in milliseconds) between
each transmission ("ping").
To change the setting, move the cursor to either side of the button. Select the left side
of the button to decrease the value. Select the right side of the button to increase the
value. Select the middle of the button to open it.If you have a keyboard connected to
