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''.
Even if RPM841-H16 input H pulse into TXD in the state of a power down, LED does not emanate.
