The Rosemount 248 communicates using the 375 Field
Communicator (communication requires a loop resistance between
250 and 1100 ohms. Do not operate when power is below 12Vdc at
the transmitter terminal). Refer to the Rosemount 248 Reference
Manual (document number 00809-0100-4825) and the 375 Field
Communicator Reference Manual
(http://www.fieldcommunicator.com/suppmanu.htm) for more
information.
Connecting a HART Communicator
The Hand-held Communicator Field Device Revision Dev v1, DD v1 is
required for complete functionality.
