Hardware setting with jumper J3 (only for devices without a display)
If jumper J3 is set, the minimum operating voltage can be reduced from 11 V to
8 V.
5.3 Communication using the HART
The set-up and measured value read out of the measuring device is done using the HART
The digital communication is done using the 4 to 20 mA current output HART
There are a number of possible set-up methods available to the user:
• Operation using the universal handheld module "HART
• Operation using a PC combined with Endress+Hauser operating software, e.g. 'FieldCare' or
®
2000' as well as a HART
'ReadWin
• Operating programs of other manufacturers ('AMS', Fisher Rosemount; 'SIMATIC PDM',
Siemens).
Note!
If communication errors occur in the Microsoft
operating systems the following measure is to be taken:
Switch off setting "FIFO active".
In order to do this follow these steps.

1. On Windows NT Version 4.0:
Select the menu point "COM-Port" using the menu "START" É "SETTINGS" É "CONTROL
PANEL" É "PORTS". Using the menu string "SETTINGS" É "ADVANCED" switch the
command "FIFO active" off. Now restart the PC.

5.3.1 HART Communicator DXR 375
Note!
®
With the HART handheld module, all device functions are selected by means of various menu
levels with the aid of the function matrix (see Fig. 12). All the device functions are explained in
chapter 6.4.1 "Description of Device Functions".
Procedure:
1. Switch on the handheld module:
– Measuring device not yet connected. The HART
appears for every HART
Information on off-line configuration can be found in the Operating Instructions of the
"Communicator DXR 375" handheld module.
– Measuring device is already connected. The 1st menu level of the device function matrix
appears directly (see Fig. 11). All the functions accessible under HART
arranged in this matrix.
2. Select the function group (e.g. Sensor ) and then the desired function, e.g. "Sensor type".
3. Enter type or change the setting. Then confirm with the function key F4 "Enter".
4. "SEND" appears via the function key "F2". Pressing the F2 key transfers all the values entered
with the handheld module to the device measuring system.
5. With the "F3" function key HOME, you return to the 1st menu level.
