2Overview
The Viator USB HART interface with PowerXpress allows you to power and communicate
with HART instruments using a personal computer's USB port and HART communication
software or an external modem / handheld communicator.
The interface is isolated and fully HART compliant. It utilizes the power available from your
PC's USB 2.x port and converts it to 24 VDC to provide 2-wire power and/or modem commu-
nications for HART field devices.The power supply includes the necessary HART communi-
cation load resistance and provides a quick modem and/or milliamp meter connection. With
this setup, all the necessary connections to the device are made with a single pair of test
clips.
The interface is enclosed in a compact, rugged polycarbonate housing, suitable for industrial
environments. It connects to your computer with a short-integrated cable that terminates in a
USB A connector.The interface connects to field devices with an integrated 6-foot cable that
terminates in 2 test clips. For power-only mode, you can use the PC USB port or the enclo-
sed wall power adapter.

•Viator USB HART interface with PowerXpress, HM-PF-USB-PWRX-010031P Ñ
•Computer with one ore more USB ports
•Windows®operating system (32-bit and 64-bit Windows®7, and Windows®10)
•HART application software for communication with HART field devices
6.2 Check Your Viator USB HART with PowerXpress
Interface Package
Your interface package contains the Viator USB HART with PowerXpress interface.
Note
HART communication software must be capable of recognizing virtual COM ports. DOS and
Windows NT-based applications do not recognize USB virtual COM ports and are therefore
not supported.
Note
The Viator software can be downloaded from the Viator USB HART interface product page
(http://www.pepperl-fuchs.com/cgi-
bin/db/doci.pl?ShowProductDocByPartNo=70138840&LanId=ENU).

6.3 Connecting to a HART Field Device
The interface has an integrated USB cable with a male A plug for connection to the compu-
ter, and it has an integrated 6-foot cable with 2 test clips.
The interface connection to the HART network is transformer isolated and polarity insensi-
tive.Transformer isolation allows you to connect the interface across the load resistor or
across the HART device. Polarity insensitivity means that you may attach either test clip to
either side of the HART device or load resistor.

Connect the test clips
1. across the HART field device or
2. across the load resistor.
6.4 Standby and Hibernate Power Saving Modes
The Viator USB Interface driver supports all portable computer power saving modes. Howe-
ver, interruption of HART communication software by a standby or hibernate mode may
necessitate restarting HART communication software to continue HART communications.
Caution!
Do not connect the Viator interface across the power supply!
This will not allow communication with the HART field device.
