HP Remote Graphics 4.2.0 User's Guide

In the network section of the RGS Receiver Control Panel, the warning timeout controls user notification if a potential network issue occurs. Under normal conditions, the RGS Receiver and Sender use sync-pulses to establish connection integrity. Sync-pulses are messages or, more appropriately, method invocations between the Receiver and Sender. If the Receiver fails to detect a sync-pulse beyond the warning timeout value, the Receiver's Remote Display Window will dim and display a warning to the user. This serves to notify the user of stale contents in the Remote Display Window. Users making critical decisions based upon data displayed in the Remote Display Window should wait until their network returns. If connectivity returns prior to reaching the error threshold (implying return of sync-pulses between applications), the Remote Display Window becomes undimmed on the next image update and normal operation continues.

If loss of sync-pulses and connectivity continues or a network invocation fails, the error timeout will trigger the Receiver to close its connection. After this action, the Receiver displays the "Connection Lost" error dialog.

A useful timeout strategy for end-users is to set short warning timeouts and longer error timeouts. With these settings the end-user detects potential network disruptions relatively quickly while allowing connections enough time to possibly recover upon network restoration. The default warning timeout for RGS Receiver is
