USB INTERFACE
The USB interface is used for CONFIGURING or MONITORING the device.
For CONFIGURATION, you must use the
NXperience
software to create, view, save, and open configurations from the device or files on your
computer. The feature to save and open configurations in files makes it possible to transfer configurations between devices and make backup
copies.
NXperience
allows you to update the
NP785 Ultra Low
Differential Pressure Transmitter
firmware (internal software) via USB interface.
For MONITORING, any supervision (SCADA) or laboratory software that supports Modbus RTU communication over a serial communication port can
be used. When connected to a computer USB port,
NP785 Ultra Low Differential Pressure Transmitter
is recognized as a conventional serial port
(COM x). Use
NXperience
or refer to the Device Manager on Windows Control Panel to identify the COM port assigned to the device.
Refer to the Modbus memory mapping in the device communication manual and its supervision software documentation to perform MONITORING.
Follow the procedure below to use the device USB communication:
•
Download
NXperience
from our website and install it on your computer (see chapter
NXperience Software
). The USB drivers required for
communication will be installed along with the software.
•
Connect the USB cable between the device and the computer. The device doesn’t need a power supply. The USB will provide enough power for
the communication operation (other device functions may not operate).
•
Launch
NXperience
, configure the communication and start the device recognition.
The USB interface IS NOT ISOLATED from the retransmission output and
alarm output. Its purpose is temporary use during CONFIGURATION and
MONITORING periods. For the safety of people and device, it should only
be used with the device fully disconnected from the external power supply
input.
In any other situation, the USB interface use is possible, but requires a
careful analysis by the person responsible for its installation.
For MONITORING for long periods and with inputs and outputs connected,
it is recommended to use the RS485, available or optional in most of our
device.
