For all configuration tools except the display, you must have an active connection to the transmitter to
configure the transmitter.
Procedure
Identify the connection type to use, and follow the instructions for that connection type in the appropriate
appendix. Use the default communications parameters shown in the appendix.
Communications tool
Connection type to use Instructions
ProLink III Modbus/RS-485
HART/Bell 202
Using ProLink III with the transmitter
Field communicator HART/Bell 202 Using the field communicator with the
transmitter
Postrequisites
(Optional) Change the communications parameters to site-specific values.
ProLink III
Device Tools → Configuration → Communications
Field communicator Configure → Manual Setup → HART → Communications
Important
If you are changing communications parameters for the connection type that you are using, you will lose the
connection when you write the parameters to the transmitter. Reconnect using the new parameters.
