Page 20: Setting The Sonar Processor To High Performance
Flexview Reference Manual Setting the Sonar Processor to High Performance To avoid slowdowns or disruptions while running the sonar, ensure your Sonar Processor is using all of its processing power and does not go to sleep. Prerequisites ® This procedure is made for the Microsoft 64-bit Windows 10 operating system.
Page 21: Installing The Flexview Software
Getting started Installing the Flexview software If your system is provided with a Sonar Processor, the Flexview software has already been installed. If you intend to use your own computer, you must install the software yourself. We recommended installing the latest Flexview software on your Sonar Processor.
Page 22: Defining The Ip Address On The Sonar Processor Network Adapter
As long as you do not change the Sonar Processor to another computer, or replace the network adapter in your Sonar Processor, you will only need to do this once. Procedure On the Sonar Processor, close the Flexview software. Open the dialog box.
Page 23: Changing The Frequency
Getting started Changing the frequency If you have a high-frequency Flexview transducer, you can change the frequency using Display Widget Context There are transducers with varying frequencies available for the Flexview.

Page 26 The ping rate is normally taken from the sonar application or range setting. If the estimated available bandwidth is less than the bandwidth required by the sonar application/range, the Flexview software reduces the ping rate to compensate. Note The update rate is the number of times the sonar view is updated per second. The displayed ping rate may be different from the update rate because the system might be impacted by other processes.
Page 27 If the Network utilization is less than 80%, disconnect the sonar, close all other programs, then reconnect the sonar. In general, make sure that your network environment supports the required link speed. In the Flexview software, look for any messages in the Output Messages window.

Page 137 That is why we normally refer to these factors as the two-way transmission loss. The TVG (Time Varible Gain) compensation is designed to counteract the natural phenomena of geometric spread and absorption loss. In the Flexview, the TVG compensation is made using digital signal processing software. By means of algorithms, the time variable gain compensation converts the echo presentation as a function of range.
