HAPTER
OPEN Setting a transmitter from POLL mode to STOP
mode
CLOSE Setting a transmitter from STOP mode to POLL
mode
where:
a = the address of the transmitter (0...99)
These commands are used to set a transmitter temporarily to STOP
mode and back to POLL mode again. The OPEN command is useful
when several transmitters are connected to one serial bus and
communication with a single transmitter is needed. The CLOSE
command is a global command and requires no address.
The PTU200 series transmitters must always be closed after the POLL
mode selection. The RESET command and powering-up will close the
PTU200 series transmitters automatically.

Example of opening and closing a transmitter with address 7:

Any commands (except for the ? command) can now be used for the
transmitter with address 7 without affecting other transmitters with
different addresses connected to the same serial interface. However, if
the RESET command is given or the transmitter is powered-up, the
transmitter will automatically return to the POLL mode.
Example of closing a transmitter:
>close <cr>
line closed
