4.4 Commands
4.4.1 Programming Messages
Some commands accept an optional suffix. This suffix can be used to specify the explicit
Q-RPT to address. In most cases, each Q-RPT in the RPM4-E-DWT operates as an
independent measurement device. If the suffix is not specified, then the “Active” Q-RPT is
assumed.
The “RANGE” or “ARANGE” command can be used to select the “Active” Q-RPT. See the
program message descriptions for suffix use with a specific command.
