6.3 Operation
6.3.1 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 measurement
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 trans-
mitter. Off-line operation permits settings common to several transmitters to be easily stored in all of them.
