Installation instructions
Use the LMA1 adapter together with LMGS Modbus RTU generic cable.
Disconnect the 3-screw terminal part from the LMA1 adapter.
Connect Data (+) and Data (-) respectively to the left and middle screw.
If the inverter cable has shielding (recommended), connect the shielding to the right GND screw.
Tip: seal the screw- and dismantled cable part with a heat shrink tube
Plug the 3-screw part back into the LMA1 adapter.
Plug the cabled LMA1 into the LMGS Modbus RTU generic cable.
Connect the USB-A side into the FlexiObox.
You will now have following connections:
FlexiObox ← USB -> LMGS ← RJ45 -> LMA1 ← screws + own cable -> Inverter

Tips
This adapter can only be used in conjunction with LMGS Modbus RTU generic cable to achieve direct serial Modbus RTU connection between the inverter and FlexiObox.
LIFEPOWR recommends using Modbus RTU rather than Modbus TCP:
Modbus RTU uses a direct serial connection between FlexiObox and inverter
Modbus TCP uses the local network and might be slightly less stable or less fail-proof
