If you have a real (or clone) BMW DK (AKA Yellow Head or incorrectly as a GT1), OPS or OPPS diagnostic head you can use the cable with your EDIABAS and with the DIS or SSS Progman. You must know the IP address of the head to use the cable select utility.
There are two basic issues with using an OEM type head.
Original “Real” DK/OPS/OPPS
First is that authentic OEM heads (used or the rare new models) often have locked IP addresses set to correspond to the workshop they were installed in. Because these heads communicate via LAN and were not typically connected directly between the car and computer, the IP address the IT department in the workshop would be one that is useable inside their company’s network. And since each device on any network must have a unique IP address, the actual address of your head could be any legal address.
Figure 103 EasyInstall - Typical network configuration for shop Clone DK/OPS/OPPS
When you are using a typical “Clone” head, it is normally much simpler to setup as they (so far as we have seen) all have a locked IP address in the expected range of this software, Most are preconfigured on the IP address range of “192.168.68.xx”. And there is NO method of changing their locked in address.
So if you’re configuring a workshop to use these heads you would have to modify the workshop LAN to match the head.
Using EZCableSelect to set EDIABAS
In the EZCableSelect program you have the option of “IP Address”. When you select this option the display changes to allow you to enter the IP address of the OEM head. There is also an additional
checkbox so that when you have an OPS or OPPS head (and possibly ICOM) you select the
“OPS/OPPS/ICOM” checkbox. This will ensure the MOST connection functions as expected.

NOTE: This ONLY configures the EDIABAS. The host computer built in LAN card settings MUST be configured to communicate on the same IP Address range as that of your OPS. If you do not do this, the LAN card will automatically assign a default address (typically in the range of 169.254.xxx.xxx) and will NOT communicate with the head.
This is due to the fact that there is no DHCP server between the OPS and the computer. In the earlier workshop image you will note that the heads are all connected to the LAN and computers through a router (or switch). This device normally (such as in the typical home network) uses what is known as DHCP (Dynamic Host Configuration Protocol) and automatically assigns and IP address to each device that does not have one pre-defined. And if the pre-defined address (such as we displayed in the VMware configuration manual IP address setting section) is on a different range than the main shop address, the system will still not connect.
For the following, our example OPS head has an IP address of “192.168.68.85” and has MOST support so that is what is entered in the following image. You MUST use the actual address of your OEM diagnostic head.

NOTE! This requires some manual configuration on your part however. The BMW heads use a real physical LAN port to communicate with the computer. This means that your physical COM Port must be manually changed to a complimentary IP address. We cannot
automatically perform this, as each BMW head can have its own unique IP address.
Configure XP for OEM Head
(BMW DK1 (Yellow Head)/ OPS/OPPS cont.)When using a real (or clone) diagnostic head you will need to manually configure your physical network IP address. Note that this will only affect the hardware LAN connection, not the wireless connection (assuming you are using a laptop with Wi-Fi).
Open your Network settings (we are using a Windows XP, which is different from Vista/Windows 7).

Using the mouse, right click on the “Local Area Connection” and from the menu that appears select
“Properties” then scroll down to “Internet Protocol (TCP/IP)” and select “Properties.
Figure 107 Configure IP address of LAN - steps. Windows XP
Enter something that is appropriate for your LAN and Diagnostic head. Here we chose “192.168.68.2” for the IP address and it automatically entered “255.255.255.0” We chose this so as not to interfere with our VMware VMnet1 network connection. Press the “OK” button on each dialog box to close. You must choose based on YOUR ACTUAL DIAGNOSTIC HEAD SETTINGS.
Configure Windows Vista/Win 7 for OEM Head
(BMW DK1 (Yellow Head)/ OPS/OPPS cont.) Configuring Vista or Windows 7 is similar, but getting to the dialog box is more difficult. Open your control panel, choose “Network and Sharing Center” (there a several ways to get here, if you know a faster way, use it).Figure 108Configure IP address of LAN. Windows Vista/7 From the left column, select “Manage network connections”.
Figure 109 Configure IP address of LAN - select LAN Connection. Windows Vista/7
Double click the left mouse button on the “Local Area Connection” (note that this is the standard name assigned by Windows to the LAN connection. However, it can be renamed, and could be on your system!) Select “Properties” then, find “Internet Protocol Version 4 (TCP/IP) and select properties. Then enter
something that is appropriate for your physical LAN configuration. You must choose based on YOUR ACTUAL DIAGNOSTIC HEAD NETWORK SETTINGS.
