When either TX-RC (2pin) input TXD (3pin) input keeps the state of ''H'' (more than appproximately 48µs),
LED will be turned off due to LED pulse width limiting circuit if the pulse is input from the other terminal.
Therefore, don't use as the normal transmitting is impossible.
Please input the pulse when both TX-RC (2pin) and TXD (3pin) are ''L''.
