BMW Battery Replacement – BSD Wire Disconnected, Negative Battery Cable. January 23, 2013. This answer is applicable for many BMWs in addition to the one listed below. Q car year: 2006 car model: 325i I had my battery (Interstate) replaced at Firestone and I noticed the Bit Serial Data Interface wire was not connected.

BMW INPA K+DCAN cable
This is a typical FTDI based interface. This is the current most used cable for INPA.
With the USB K+D CAN type cables there are a few installation steps, drivers & a little software that you need to make them work properly. This does 2001-on cars right up to & including 2011 cars (may be limited by the hookie software for cars after June 2008 on a diminishing basis as the car gets newer). This cable is a USB enabled device, again you will need to install the USB to serial drivers. However you will also need to install the K+D CAN utility, this allows you the ability to switch it from a K CAN device for pre-2007 cars (see list above) to a DCAN cable. There are two versions of this utility, a fancy GUI & a MS DOS one. I find that the MS DOS one works best.
Hera’s an image of what this cable looks like:
Ediabas ADS/OBD interface Serial Port cable
As mentioned previously the ADS interface is a different protocol, if you don’t have an ADS interface with an e36 then what you’ll be able to read with a regular OBD cable is limited. Unfortunately the ADS interface seems to be the hardest to get & most expensive of all the interfaces. It works fine on the e36, e39 & e63 (note my e63 is pre-March 2007) from my personal experience.
Suitable for e36, e34, e30
Here’s a picture of the Ediabas ADS interface:
Non-ADS Serial port interface
This is a cheap interface & is readily available plus requires no modification. It works just fine on E46/E39 with either the round 20 pin connector under the bonnet or the OBD2 port in the drover’s footwell. Set up of this cable is straight forward, no drivers required.

INPA + 1.40+2.01+2.10 4 in 1 BMW Scanner
This is a interface contains four software of BMW scanner INPA K DCAN cable + BMW DASH E6x V2.1.0 + BMW Scanner V1.4.0 + BMW Scanner V2.10 cable. The scanner comes with INPA OBD, ADS interface and none ADS cable for all all systems (K-line and CAN-BUS) of BMW series and OBDII diagnostic system.
Carsoft 6.5 Interface
CarSoftware interface can be modified to work with INPA, but it is not recommended. When you first got INPA, you have to run a carsoft test to “initiate” the lead every time. What a PITA, stay away from this solution! The black serial cable below only works on OBD1 cars like pre 2001 e39 and this will work for all K CAN (e36, e39, e46, e53, e63).
BMW ICOM A2+B+C emulator
BMW ICOM Rheingold not only comes with basic ISTA-D ISTA-P diagnostic & programming software, it comes with lots of engineering software, INPA, EDIABAS, WinKFP, NCS-expert, NCS-dummy etc. So INPA is well loaded to BMW ICOM A2+B+C diagnostic system, but you need to do some configuration work. This is quite good for experts and technician.

In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels.
Serial communication is used for all long-haul communication and most computer networks, where the cost of cable and synchronization difficulties make parallel communication impractical. Serial computer buses are becoming more common even at shorter distances, as improved signal integrity and transmission speeds in newer serial technologies have begun to outweigh the parallel bus's advantage of simplicity (no need for serializer and deserializer, or SerDes) and to outstrip its disadvantages (clock skew, interconnect density). The migration from PCI to PCI Express is an example.
Cables[edit]
Many serial communication systems were originally designed to transfer data over relatively large distances through some sort of data cable.
Practically all long-distance communication transmits data one bit at a time, rather than in parallel, because it reduces the cost of the cable. The cables that carry this data (other than 'the' serial cable) and the computer ports they plug into are usually referred to with a more specific name, to reduce confusion.
Keyboard and mouse cables and ports are almost invariably serial—such as PS/2 port, Apple Desktop Bus and USB.
The cables that carry digital video are almost invariably serial—such as coax cable plugged into a HD-SDI port, a webcam plugged into a USB port or Firewire port, Ethernet cable connecting an IP camera to a Power over Ethernet port, FPD-Link, etc.
Other such cables and ports, transmitting data one bit at a time, include Serial ATA, Serial SCSI, Ethernet cable plugged into Ethernet ports, the Display Data Channel using previously reserved pins of the VGA connector or the DVI port or the HDMI port.
Serial buses[edit]
Many communication systems were generally designed to connect two integrated circuits on the same printed circuit board, connected by signal traces on that board (rather than external cables).
Integrated circuits are more expensive when they have more pins. To reduce the number of pins in a package, many ICs use a serial bus to transfer data when speed is not important. Some examples of such low-cost serial buses include RS-232, SPI, I²C, DC-BUS, UNI/O, 1-Wire and PCI Express. In IC, serial bus may be typically implemented by using multiplexer (which utilizes technique called multiplexing).[1]
Serial versus parallel[edit]
The communication links, across which computers (or parts of computers) talk to one another, may be either serial or parallel. A parallel link transmits several streams of data simultaneously along multiple channels (e.g., wires, printed circuit tracks, or optical fibers); whereas, a serial link transmits only a single stream of data.
Although a serial link may seem inferior to a parallel one, since it can transmit less data per clock cycle, it is often the case that serial links can be clocked considerably faster than parallel links in order to achieve a higher data rate. Several factors allow serial to be clocked at a higher rate:
- Clock skew between different channels is not an issue (for unclocked asynchronous serial communication links).
- A serial connection requires fewer interconnecting cables (e.g., wires/fibers) and hence occupies less space. The extra space allows for better isolation of the channel from its surroundings.
- Crosstalk is less of an issue, because there are fewer conductors in proximity.
In many cases, serial is cheaper to implement than parallel. Many ICs have serial interfaces, as opposed to parallel ones, so that they have fewer pins and are therefore less expensive.
