Appendix A
HART Communicator
INTRODUCTION
This appendix provides basic communicator information on both the 
Rosemount 275 and Rosemount 375 HART Communicators when used with 
a Rosemount 3051N Smart Pressure Transmitter. The Rosemount 275 and 
Rosemount 375 HART Communicators are not qualified, but may be used as 
Measurement and Test Equipment (MTE) as documented in Rosemount 
Report D2001019.
When the HART Communicator is referenced, it refers to either the 
Rosemount 275 or Rosemount 375.
This brief appendix will familiarize you with the HART Communicator but is 
not meant to replace the HART Communicator product manual. For additional 
information on the HART Communicator, refer to the HART Communicator 
Product Manual, publication number 00809-0100-4275 (Rosemount 275) or 
00375-0047-0001 (Rosemount 375).
NOTE
You may need to upgrade the software in your HART Communicator in order 
to take advantage of all features of the Rosemount 3051N. If you initiate 
communication with a Rosemount 3051N using a Communicator that has a 
previous version of the transmitter Device Descriptors (DDs), the 
communicator will display the following message:
Notice: Upgrade software to access XMTR function. Continue with old
description?
If you select YES, the communicator will communicate properly with the 
transmitter using the existing Rosemount 3051N DDs. However, software 
features added since the revision of the DDs in the communicator will not be 
accessible. If you select NO, the communicator will default to a generic 
transmitter functionality. Contact Rosemount Nuclear Instruments, Inc. at 
(952) 949-5210.
