7.3 Operation
7.3.1 Off-line and On-line Operation
The Model 375 Communicator features off-line and on-line communications. On-line means the communicator is
connected to the transmitter in the usual fashion. While the communicator is on line, the operator can view meas-
urement data, change program settings, and read diagnostic messages. Off-line means the communicator is not
connected to the transmitter. When the communicator is off line, the operator can still program settings into the
communicator. Later, after the communicator has been connected to a transmitter, the operator can transfer the
programmed settings to the transmitter. Off-line operation permits settings common to several transmitters to be
easily stored in all of them.
