[Paragrouper]

Warning; Before anyone responds to this gentlemans specific technical questions, please review the Department of State's regulations regarding the export of technical data outside the United States.

While the OP asserts he is a US citizen, he is physically located outside the United States and any information sent to him may constitute an export. I work for a British owned company and we have an extensive interaction with both the Department of State and the Department of Commerce in order to conduct business with a parent company. Thus, we are very careful to stay within the laws and regulations governing export of material and technical data. If a query similar to this came into our office, we would decline to answer. The questions may seem to be innocent, but your responses may include US technology and know how the US Government may control.

To the OP; I strongly suggest you stop, regroup, and carefully consider the rules of our house before you post further.
