1. Mode Setting (SIR / MIR / FIR)
With RPM972-H14 there is a need for mode switch according to communication rate. For the mode setting, there
are PWDOWN/Mode and TXD . Please see below diagram for the set up of mode.

2. Remote control transmitting
When remote control signal is input to the TXD terminal, remote control is transmitted.
3. Timing chart (use example)
(a) Emitting
When a pulse is inputted to TXD terminal, LED is emitting, and a signal is transmitted.
But, when H condition follows TXD terminal, LED turns off the lights in the range of TLEDmax.
TLEDmax
more than TLEDmax
less than TLEDmax
