Can anybody help ?. We provide trailer telematics devices GPS etc etc. We want to integrate it with reefer trailers, initially Carrier and Thermo King so that we can remotely gather temperatures and any other data available.

I need to know what data can be easily collected, is there typically a data port we can gather the data from ? what is this data bus, RS232 / 485, CAN etc.

Does anyboday have the protocols for communicating to/from the fridge units ?

We are willing to pay for any consultancy work

Thanks
