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.
