Bmw ethernet in depth ? (ENET)
Hello guy`s
i`m looking for specifications and informations about BMW ethernet. i`m looking for stuff like: * whats running over ethernet (devices ?) * known protocols ? * encryption ? * hardware topology (switches ?, cabling ?, ECU`s ? ) * connectivity (OBD 2 only via activation ?, direct access to the switch ? ) I saw that the F series do have ethernet for sure, but also some E model`s do have ethernet at the CIC-Pro, but for what reason/features ?

RE: Bmw ethernet in depth ? (ENET)
Thanks for your answer.
I have already found some of the informations at ISTA-D , but not all of them. what i have not found is where the eth of the CIC on E series is connected to, and what the pinout of the eth connector on the CIC is. the reason why i`m looking for that information is that i retrofit a CIC-pro which has a ethernet connector into my E87 and want to use the ethernet port to upload files, but have not found the neccessary information if i can connect directly to the port or if i do need a ZGM which i have also not found at ISTA.

E-net from cic in Exx cars goes directly to OBD connector, you can find it in ISTA.

RE: Bmw ethernet in depth ? (ENET)
Ethernet in the E Series is only up to
transferring maps and data to disk, this is the information in ISTA D, Ethernet (DoIP ) in the F and G series it's a communication interface it is started by connecting pin 8 (the ethernet port itself is inactive, without connecting the pin 8) in ENET it is a resistor of 511 ohm 0.6W (to pin 16) + 12V pin 3 pin 11 pin 12 pin 13 it does not require electronics, just an Ethernet cable and you can connect like two computers If my post helped you hit the thanks and reputation button!

RE: Bmw ethernet in depth ? (ENET)
Thanks for your replies, thats good to hear that the Enet port goes directly to the OBD port when originally equipped.
but as i`m doing retrofit the question is what is the pinout of the orange ethernet connector at the CIC, as i want to mount a RJ45 network socket directly into my glove compartment. All i find at ista (and TIS) are pictures with definitions of the CIC`s that have not the orange HSD ethernet connectors but only the CID and USB HSD connectors. Kri |

RE: Bmw ethernet in depth ? (ENET)
I don't know if you are aware but the orange connector is ethernet for RSE (rear seat entertainment).
Not entirely sure that it would act as a standard ethernet port into the CIC. I am happy to be corrected though. If you want info on connections then select a 7 series via operations -> basic features in ISTA+. Alternatively if you want ethernet in the glove box then you can use a D-Link DUB-E100 version B1 to connect ethernet to the USB port in there. |

Quote:I don't know if you are aware but the orange connector is ethernet for RSE (rear seat entertainment). I know that the orange is descibed as RSE, thats why i was asking for the hardware topology, to identify if all ethernet devices incar will run over the same connection (like on PC networks, all pc`s are connected to the same switch) From what i read until know (didn`t knew that before) it seems that the CIC also has a Ethernet Connector on the Quadlock plug. Quote:Alternatively if you want ethernet in the glove box then you can use a D-Link DUB-E100 version B1 to connect ethernet to the USB port in there. Now i get it, i first thought the this Adaptor will be used the normal way , to be connected to a ENET->ODB2 cable, so understood it the wrong way. But it seems that the B1 (old grey) Adaptors are hard to get, and the newer black one (C1) do not work. Quote:Not entirely sure that it would act as a standard ethernet port into the CIC. I am happy to be corrected though. If you want info on connections then select a 7 series via operations -> basic features in ISTA+. Thx, this way i know found the CIC with the ethernet connector (A42*10B),there only is written "Ethernet" and not the exact pin assignement. But i was able to find the assignment now at newtis with the Connector number so next thing is to check if this connector is always active (no 5th pin for activation), or is able to activate it for example with an RSE FA Kri |

Quote:You must connect Eth_A using a resistor for the line to stay up The Orange ethernet connector does not have an Eth_A pin, HSD cables have only four pins, and that four pins ar RX+/- and TX+/-. therefor i think this connection is either always on, or will be activated via software. i also came to a conclusion that there has to be some kind of switching fabric buit in into the CIC, because basicly there are now three possible physical ethernet connections. * OBD2 connector -> CIC Quadlock * Glovebox USB Connector via DUB-E100 * HSD Cable -> RSE Kri |
