K Dcan Setup

Here, I will chip in with a few words of the reason why you should have Pin 7 and Pin 8 on your K+Dcan cable and how to use the switch mode

BMW INPA software works with INPA K+DCAN Interface. VXDAS.COM has INPA K+DCAN cable with and without switch for BMW. Here provide INPA windows 7 download link here. INPA Windows 7 Download Software version: 5.0.2 (tested ok) VXDAS team also glad to share the installation guide for INPA software with Win7 32bit. Check details below. So, got my self a high quality INPA K+DCAN Interface from China. Interface looks very well designed and has a nice PCB, all components soldered properly on the board. Installed BMW Standard Tools 2.12 as per instructions of our friend Bimmer with all software he provided in his thread.

Connection by soldering is a bad option as it limits the usefulness of the interface, I have an adapter but consider a switch to be a better option

With theseK+DCAN cables there are two subtle different versions, one with pin 8 enabled, one with it disabled. The one with it disabled is ideal for e90 newer than 03/07 & that era, these leads often come with a black adapter to re-enable the pin 8 (by just tying it to pin 9) so it will also be suitable for e46/e39/e63 etc. The ones with pin 8 active are just older versions of the cable. Worst cast scenario you just need to modify the cable & stuck a switch on it to toggle pin 8 on/off as needed.

The reasons being that on DCAN cars one pin is used for a ethernet connection and the other to the K data line – on K line cars, both pins are connected to K data lines and that creating a switch mode circuit would cost more than the interface is worth. The 2 most sensible options are both hardware-related:-

– Use an adapter (such as the one sold by One Stop electronics) which internally bridges pins 7 & 8 or…

– Mount a small switch on the OBD plug end of your adapter, which can bridge (for K line) or separate (for DCAN) the connection between pins 7 & 8.

As soon as you connect the interface to the car and your computer, run DCAN.exe to configure the comms rate. I have only used the K+DCAN interface with DCAN cars.

Fyi, You only need to run DCAN.exe when you are switching between modes. If you run it the first time you connect to a DCAN car, your computer will retain the settings.

Switch K+D CAN adapter between K and D CAN protocols for use, depends on the car that is connected.

The last, K+DCAN cable you see the PCB
Very fine work, bridged soldering of 2 pins is intentional.

2. Open “Device Manager”, then USB Serial Port properties, go to “Port Settings” tab and click “Advanced…”. Change port number to “COM9” and latency timer to “1”. Confirm configuration via “OK” button.

3.Open C:EDIABASBINEDIABAS.INI with Notepad and check for “Interface = STD:OBD”. In TCP settings set “Port = 6801”.

4.Open C:EDIABASBINOBD.INI with Notepad and check for “Port=Com9”.

5.Connect car with K+D-CAN cable to PC.

6.Now run BMW Rheingold ISTA using shortcut in start menu and wait until it boots, then press settings button.

7.Select “VCI Config” tab and “Ediabas standard settings (ediabas.ini)”, then “OK”.

8.Go “Operations”, then “Read Out Vehicle Data” and “Complete Identification”.
