In auto-switching mode, front panel button control is not available, but IR and RS232 control is able to switch modes. 4.1.2 Switching Operations Support auto-switching and manual-switching. Press and hold on SOURCE/AUTO button for 7 seconds or more to enter in auto-switching/manual-switching mode. The display result is showed as below: The display result will be showed for 2 seconds. The auto-switching mode follows the listed principles:  New input principle Once detecting a new input signal, SC51D would switch to this new signal automatically.  Power rebooting principle SC51D offers the function to remember the signal last displayed when rebooting. Once rebooting, SC51D will automatically enter in auto-switching mode, and then detect all inputs and memorize their connection status for future rebooting using. And if the signal last displayed is still available, then SC51D will output the signal. If not, there will be no signal on outputs.  Signal removing principle Once removing the current display signal, SC51D will detect all input signals with priority (from INPUT 1 to INPUT 5). It will output the signal firstly detected to be available. Notice: Auto-switching function works only when there is new input signal, or when users remove a signal or power rebooting. With any VGA port set to AV or YPbPr, the system will be not able to enter in Auto-switching mode. Operation Examples:  Connect the INPUT 2, INPUT 4, and INPUT 5 ports to the source devices, select INPUT 4 to outputs.  Press and hold on the front key SOURCE/AUTO for 7 seconds or more to enter in auto-switching mode.  With no signal removing or new input, SC51D just works in auto-switching mode, and take no action (Output from INPUT 4) IN: HDMI1 AUTO 1280 X 720 IN: HDMI1 MANUAL 1280 X 720 Auto-switching function

PTN Electronics Limited 9 www.PTN-electronics.com  Connect INPUT 3 with a source device, and then it will choose INPUT 3 to output.  Remove the signal of INPUT 3, SC51D will detect from INPUT 1 to INPUT 5. And when it detects that input 2 is available, it will choose INPUT 2 to output.  Cut off the power of SC51D, then reboot. As SC51D is in auto-switching mode, then it will choose INPUT 2 to output. 4.1.3 Software Updating Software updating means to update the inside program of this scaler switcher.
