Operating modes
Select the desired sending mode for the transmitter. This is done with
a command SMODE.
SMODE Selecting the sending mode
SMODE x <cr>
where:
x = STOP, RUN, SEND or POLL
The SMODE command is used to set or inspect the sending mode of
the transmitter. The PTU200 series transmitters have four sending
modes: STOP, RUN, SEND and POLL.
In STOP mode, after power-up the transmitter outputs its type and
software version and then waits for further commands.
In RUN mode, continuous outputting starts automatically from power-
up.
In SEND mode, a single message is automatically output after power-
up.
POLL mode allows the communication with multiple transmitters or
other digital instruments connected to one serial bus. The transmitter
does not echo in POLL mode.
Examples:
>smode <cr>
