This page provides fixes for some known problems that can occur with live viewing.
The device running Echolog can see the (host) computer on which the echosounder data is saved but Echoview can not start live viewing. You may need to configure folder/file sharing on the host and the device running Echolog.
Data being sent by an Echolog application may not be detected on a machine where the Windows (XP/Server 2003) Internet Connection Firewall is enabled. This problem may occur regardless of whether Echolog and Echoview are being run on the same or different machines.
The Internet Connection Firewall is enabled by default when Windows XP with Service Pack 2 is installed. The same service pack enables you to allow exceptions (programs which are permitted to communicate through the firewall). Echoview can be enabled as an exception or the firewall can be disabled completely. We recommend you apply Service Pack 2.
If you are not sure how to configure the Internet Connection Firewall use the Windows XP Help and Support Center (or visit the Microsoft support site ) and search for "Internet Connection Firewall".
On many local area networks IP addresses are allocated dynamically by a DHCP server. These addresses can expire after a certain period of time (commonly 24 hours), and a new IP address is allocated if still needed. Typically the same IP address is reallocated to the same machine but it is also possible that a different IP address is allocated. If a different IP address is allocated to the Echolog and/or Echoview machines during a live viewing session this will break the link between the two machines and live viewing will stop.
If you suspect this may be occurring, please contact your local area network manager and ask them to:
assign a static (non expiring) IP addresses to the Echolog and/or Echoview machines, or
extend the expiry time of the dynamic IP addresses.
Echoview will crash during live viewing if the size of the file(s) being logged exceeds available memory. To ensure this does not happen:
enable automated EV file management and enter appropriate settings on the Live Viewing page of the Echoview configuration dialog box, and
monitor live viewing and clear any modal dialog boxes that are displayed (these suspend automated file management until cleared).
Linking a 2D projections or Single target angles graph to an extending selection will eventually lead to poor performance or crash Echoview. The number of data points within a selection affect the system resources needed to redraw these graphs. In a Power user's computer, performance may start to deteriorate for an extending selection containing more than 1000 data points and a crash may occur with more than 3000 data points.
There is known issue with the classification of schools while live viewing. The classification of schools can differ when applied to an echogram after live viewing and when applied while live viewing. The issue is associated with a mismatch between pings and (live-viewed) GPS position.
