Checking the serial port network operation
Normally, measurement readings are asked when the transmitter is in
POLL mode; then the command must include the address of the
transmitter. If the settings of the transmitter need to be changed, the
transmitter is switched to STOP mode with command OPEN;
commands can then be given without address. When the line to the
transmitter is closed, it returns to POLL mode.
STOP mode
Open the line to the transmitter:
open 22<cr>
DMP 22 line opened for operator commands
Transmitter no. 22 is now temporarily set to STOP mode; it accepts
commands without address until CLOSE command is given.
Individual settings can now be easily modified. Do not open more
than one line at a time.
Use command ? to find out the settings of the active transmitter:
