Configuration
62 265Gx, 265Ax IM/265Gx/Ax-EN-07
7.7 Configuration with the PC / laptop or handheld terminal
A graphical user interface (DTM) is required for configuration of the transmitter via PC or laptop.
For operating instructions, please refer to the software description.

Communication protocol
HART
®
PROFIBUS PA
®
FOUNDATION Fieldbus
Hardware (for HART
®
)
FSK modem for PC or laptop
HART handheld terminal (HHT) e.g., 691HT, HHT275/375, DHH800-MFC
You can use a handheld terminal to read out or configure/calibrate the transmitter. If a
communication resistor is installed in the connected supply unit, you can clamp the handheld
terminal directly along the 4 ... 20 mA line.
If no communication resistor is present (min. 250 ), you will need to install one in the line. The
handheld terminal is connected between the resistor and transmitter, not between the resistor
and power supply unit.

IMPORTANT (NOTE)
Communication / configuration / parameterization via handheld terminal / PC where type of
protection "intrinsic safety" applies: In this case, the HHT / PC must be appropriately certified;
this applies even if it is only connected for a short period of time. This proof of "intrinsic safety"
must be supplied in addition to the transmitter.
With type of protection "flameproof enclosure Ex d", the handheld terminal must not be
connected in a potentially explosive atmosphere.
The HHT battery must not be replaced in a potentially explosive atmosphere.
