21. s unexpectedly dropped The volume continues to rise possibly damaging equipment until a stopir command is ultimately received The Netkit solution is to limit the repeat count Hence to create a smooth IR operation the Netkit resets the IR repeat count each time the identical IR command from the same IP connection is resent This method will not interrupt and restart the IR command but reset the IR repeat count back to the original value Example If the IR repeat count is set to 5 and the IR command has transmitted 3 times receipt of the same command causes the repeat count to be reset back to 5 This process can continue indefinitely while a volume button is held down to create a smooth operation However at no time can the command repeat more than 5 times after the button is released or an IP connection is inadvertently lost preventing a potentially serious issue By selecting an appropriate lt repeat gt value the need for a stopir command is eliminated In this example the volume continues to increase smoothly by retransmitting repeated IR commands due to the volume button being pressed As long as the next repeated IR command is received before the previous command finishes smooth operation is realized By choosing a low repeat value the volume increase will stop when the volume button is released Also proper IR operations happen even with unintended network delays due to traffic or WiFi connectivity In this unlikely event on
