OPEN and CLOSE commands are used to set a barometer momentar-
ily to STOP mode and back to POLL mode again. This command is
very useful when several barometers are connected to one RS 232C
bus and only one individual barometer needs to be contacted.
Example of communication with a barometer with address 7:
>OPEN 7<cr>
PTB 7 bus opened for operator commands
(normal commands can now be used without disturbing other
barometers on the RS 232C bus)
>CLOSE 7<cr>
bus closed
(the barometer with address 7 is set back to the POLL mode and
only SEND 7 and SMODE 7 STOP commands work)
Please note that when leaving the POLL mode, command CLOSE must
always be followed by the address of the barometer.
