LIN (Truma LIN, Caravan LIN): J11, J12, J13, J14

J11/J12 provides LIN 2, J13/J14 provides LIN 1.

Pin Assignment

Each interface has a 2-pin Microfit connector (pins: GND and LIN) and an RJ12 connector for cables of Truma’s LIN-based protocol and the Caravan LIN Protocol. Both connectors (RJ12 and Microfit) are wired in parallel internally, so devices can be connected via the RJ12 (e.g. Alde display) and via the Microfit connector (e.g. Dometic AC) at the same time. Both devices must use the same protocol, e.g. CI-Bus

Please note: For devices that are not galvanically isolated and share the same ground as the Core, no additional ground connection via GND is needed. This prevents ground loops.
