Power supply voltage

With 2 units and a few simple external components, you can begin experimenting wit an ultra small remote controller
Transmission and reception of 8-Port Digital signal (ON/OFF) is possible. Transmission and Reception can be switched with settings. Tranmission power can be set to either of two levels Hi/Lo.
Port outputs at receiver side can be inverted.
Simultaneous use of 4 units is possible with channel switching. (Receiver side outputs are held at their present states in case of received signal interruption)
