* DS1 is connected to A. If D6 switch is on among DS1 , A becomes D6 port.
* DS2 is connected to B. If D7 switch is on among DS2 , B becomes D7 port.
* If D6 switch among SW49~SW56 is on at D, the key 49~56 can be used as D6 port.
* If D7 switch among SW57~SW64 is on at D, the key 57~64 can be used as D7 port.
* note : the position of SW49~56 and SW57~64 in B/D is changed. The reference position is right.
* If you want to increase the remote controller valid distance, you try to disconnect R2 resistor
and lessen R1 resistor.
