When you open the "SIPLACE OIB Connector" (in the 'Machine Export' menu) the first time, you have to first enter your OIB server settings by clicking on the gear button (1): 

Following dialog will open:

In this server manager, you can organize multiple OIB servers. To create a new one, please press on the little green "+" button and enter a name.
Afterwards you'll have to specify the OIB server adress by entering an IP/Hostname + Port, or directly enter the 'net.tcp://...' adress (1).

When this is done, you'll have to specify two server directories by clicking on the small browse button (2):

• "Component Main Path": This is the OIB directory, where your part library is located. Parts in this directory are only read, but never written or changed.
• "Component User Path": This is the OIB directory, where parts, that do not exist in the main path yet, are created by PCB-Investigator. The user has to complete the information of those parts in the SIPLACE Software and can then move them to the main path later.

Click "Save" and close the dialog to preceeed.
