CHAPTER 5
OPERATING
Only a few commands are needed to operate a PTU200 transmitter in
the RUN, STOP and POLL modes. In the SEND mode, no commands
are needed.
In the RUN or STOP modes, the commands R, S and SEND can be
used. The user may also use his own SEND command if he has
previously specified one using the SCOM command.
In the POLL mode, the transmitter responds to a SEND command
only if it includes the address. OPEN and CLOSE commands are also
available for temporary communication with one single transmitter.
In the SEND mode, no commands are needed. The transmitter will
automatically output one message at power-up, or when triggering the
transmitter on using pin 4.
