ASSEMBLY
The device can be mounted in any position, in compliance with the expected environmental conditions. Use the
accessories supplied for xing on a DIN rail.
Attention: magnetic elds of considerable magnitude can alter the measurement: avoid proximity to permanent
magnetic, electromagnetic elds, or ferrous masses which induce strong alterations of the magnetic eld; possibly,
if the zero error is greater than the declared error, try a different arrangement or change orientation.

The module is designed to exchange data according to the modes dened by the MODBUS protocol. It
has a micro USB connector and can be congured using applications and/or software programs. The USB
communication has priority over the RS485 communication.
The USB serial port uses the following communication parameters: 38400,8,N,1
The USB communication port responds exactly like the RS485 port with the exception of the communication
parameters. During the use of the USB port, the 485 bus will be inactive; it will reactivate automatically a few
seconds after the release of the USB port. EASY SETUP is the software to use for the conguration. For further
information go to the website on the cover.
Check that the device in question is included in the list of products supported by the Easy Setup APP in the store.
