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>
Serial mode

: STOP

>smode run <cr>
Serial mode

: RUN

>smode send <cr>
Serial mode

: SEND

>smode poll <cr>
Serial mode

: POLL

>smode stop <cr>
Serial mode

: STOP

>reset<cr>

NOTE

Remember to give the RESET command to initialize the new sending
mode.
