Compact Scaler Switcher (with PoC)
PTN Electronics Limited 9 www.PTN-electronics.com
The auto-switching mode follows the listed principles:
 New input principle
Once detecting a new input signal, SC51T would switch to this new signal
automatically.
 Power rebooting principle
SC51T offers the function to remember the signal last displayed when rebooting.
Once rebooting, SC51T 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 it will choose the signal to output.
If not, there will be no signal on outputs.
 Signal removing principle
Once removing the current display signal, SC51T will detect all input signals with
priority from INPUT 1 to INPUT 5. It will transfer the signal firstly detected to be
available to outputs.
Notice: Auto-switching function works only when input with new signal, remove a signal
or power rebooting.
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 3 seconds or more to enter in
auto-switching mode.
 No signal removing or new input, SC51T just works in auto-switching mode, and
take no action (Output from INPUT 4)
 Connect INPUT 3 with a source device, and then it will choose INPUT 3 to output.
 Remove the signal of INPUT 3, SC51T 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 SC51T, then reboot. As SC51T is in auto-switching mode, then it
will choose INPUT 2 to output.
