SEND mode
In the SEND mode, the transmitter will automatically output one
message at power-up or when triggering the transmitter on using pin 4
of the transmitter. The trigger signal must be a TTL level signal. TTL
HIGH (5 VDC) turns the transmitter ON and TTL LOW (0 VDC)
turns the transmitter OFF.
Examples of outputting with the prompt (ECHO ON) and without the
prompt (ECHO OFF):
