The POLL mode is used when several PTU200 series transmitters are
connected to one RS232C serial interface. It is also used when several
intelligent transmitters are connected to a half duplex RS 485/422
serial interface.
In the POLL mode, the transmitter must have a specific address so
that the host system is able to direct the outputting commands to the
particular transmitter. The addressable SEND command is used to ask
for a single message output from the transmitter.
The OPEN command can be used to open a single transmitter
temporarily to STOP mode. The CLOSE command will restore the
POLL mode.
SEND Outputting one single message
SEND a <cr>
where:
a = the address of the transmitter (0...99)
This command is used to output one message from the transmitter in
the POLL mode (see SMODE command).
Example:
>addr 7 <cr>
Address
:
7
>smode poll <cr>
Serial mode
: POLL
>close <cr>

send 7 <cr>
