15. Electromagnetic compatibility
This product conforms to CENELEC EN 61326-1:2013 class A requirements for electromagnetic
interference (EMI) suppression. EN 61326-1:2013 is equivalent to international standard IEC 61326-
1, Ed. 2.0 (2012-07).
16. Firmware update procedure
The controller firmware can be updated using the serial RS485 interface and a specific PC
application named
LTDVE firmware updater
Figure 19: main window of LTDVE
presents the main window of the PC application.

It is necessary to specify the communication port on the PC the controller is connected to. The baud
rate is fixed at the maximum speed of 460,800 bits per second.
Inside the controller there are two programmable components, a MCU (Micro Controller Unit) and a
FPGA (Field Programmable Gate Array), that must be updated at the same time. Failure to comply
with this principle can lead to controller malfunction. The two small buttons at the right side are used
to locate the relevant programming files in the PC file system.
To update the FPGA firmware it is necessary to specify a couple of files, named the FPGA Algo file
and the FPGA Data file. After pressing the
Load FPGA files
dialog used to locate the FPGA Algo firmware file
will be displayed, asking to specify the FPGA Algo
file.
