Hi everyone, recently did E60 EVO retrofit with NBT adapter from carsystems. All is good, i tried the OABR coding method on bench, all worked fine when connected directly to RJ45. I then crimped 4 female OBD pins to the OABR, connected to my ENET cable, with one cable it wouldn't work, but with another one it did. I then went in car, installed the OABR and OBD pins in the exact order in car, but in car i can't get a connection. Why is this? Anyone got this working?
EDIT: I connected only 4 pins for TX and RX connection, since this worked fine on bench.

happened to me once , I had to connect the ETH-A pin8 from obd socket to Quadlock pin 29

Very weird is it all works on bench. After connecting ETH-A, do i need some resistor or something?

exactly , very weird but that was the solution for me.

If you are going to use Enet cable which is used for F and G series coding, then no need to add any resistor as the 512ohm resister already inside the OBD socket of the Enet cable.

Okay, im gonna try to add the pin, and let you know. Thanks

Hi, added pin 29 on quadlock to pin8 on OBD2. Same result, i get network identification, but can't ping EVO.

and you are sure that the other 4 wires are pinned correctly?
I have attached 2 files, you have to combine them....
OBD2 (PIN3,8,11,12,13) and the other on HU (PIN29,31,32,37,38)

and you are using ENET Interface for F and G series?

Hi, i am using the correct cable. I did 4 wires from OABR to OBD, TX and RX. I also did ETH_A from quadlock 29 to OBD pin 8. What is currently happening is: On bench, i connected OABR to RJ45, all is fine. In car when i put the pins to OBD, i get unidentified network, which means it has some connection somewhere, but i can't ping EVO or connect via gateway. Car is E60 with eNBT adapter, maybe it is messing with the communication? I also tried to disconnect the fuse where the eNBT is wired to, i get same result.

and if you set your IP on laptop manually?
it doesn´t make a sense..because the 5 wires from oabr should go directly to obd2, so if there no one of them broken it shouldn´t make a difference where you are connected (bench or obd2 in car)

If you measure resistance on OBD between rx and tx pairs, what do you get?
