INTV Setting the output interval

INTV x y <cr>

where:

x = output interval (0...255)

y = unit (s, min, h)

This command is used to set and inspect the interval output mode. The

R command is used to start the outputting.

Examples:

>intv <cr>

Output intrv. : 0 s

>intv 10 s <cr>

Output intrv. : 10 s

>r <cr>

NOTE

In case of the half duplex RS 485/422 serial communication, the user

is requested to set the interval time to one second or more. This

enables an interruption of outputting, if the R command is given by

mistake. See page 93 for quick reference information on how to use

the RS485/422 interface of the PTB220 series barometers.

ADDR Setting the barometer address (for POLL mode)

ADDR x <cr>

where:

x = the address (0 ... 99)

This command is used to set and inspect the address of the barometer

for the POLL mode (see Chapter POLL mode). The address feature is

important when multiple PTB220 series barometers are connected to

one RS232C interface (see page 91), or when a PTB220 series

barometer is used on an RS485/422 serial interface (see page 93).

Example of setting the address to 7:

1 2 ... 28 29 30 31 32 33 34 35 36 37 38 ... 112 113
