Defining the ping (transmission) modes
You can easily control how often the SX90 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
Once pinging is
On
, use
Transmission Mode
to choose
how
often
the SX90 shall transmit (ping). Use it to control the
behaviour
of the transmissions (pinging).
•
Single Ping
: The SX90 transmits (pings) only when
you select the symbol on the right side of the button.
•
Interval
: The SX90 transmits (pings) with a fixed time
interval.
Ping Interval
permits you to choose the time
(in milliseconds) between each transmission (ping).
•
Maximum
: The SX90 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 SX90 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.
or:

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 SX90, you can type the requested value.
