[OLD] LogicMachine firmware 2019.10

[Boris]

Sure, this question may sound very trivial to most of this forum's members, but to me as a newcomer many things are to be learned - such as; 
in case of a FW-upgrade, what package should be installed on a "LogicMachine5 Power KNX CANx"?


Is it "LM5 Power 4 DIN units: https://dl.openrb.com/lm-19-imx6/lm5m4-20191015.img"? ... as the "LogicMachine5 Power KNX CANx" uses 4 DIN units

or

is it "LM5 Power Lite: https://dl.openrb.com/lm-19-imx6/lm5m3-20191015.img"? ... as under "Upgrade firmware" it is mentioned: "HW: LM5 Lite..."

or is it even "LM5 Power with extensions: https://dl.openrb.com/lm-19-imx6/lm5m3ex-20191015.img"? ... as under "Upgrade firmware" it is mentioned: "... + Ext (i.MX6)"
