16. 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).
In case of long cables electromagnetic interference may be counteracted by inserting ferrite cores
on the power supply and light cables. In case, suggested parts are Würth Elektronik 74271221, to
be applied with up to 3 turns of the cables.
17. Firmware update procedure
The controller firmware can be updated using the serial RS485 interface and a specific PC
application named
LTDVE firmware updater
.
The first step is to connect the controller to be updated to the PC on which the LTDVE firmware
updater application will be run. If the PC does not have a native serial RS485 interface, a RS485-
USB adapter like the ADPT001 may be used. On the controller end, the serial RS485 interface is
available on the D+, D- and GND terminals of the male D-shell connector P5. Data signal D+ is pin
15, data signal D- is pin 7 and the reference ground GND is pin 8.
