I now have both version 1.84a and version 1.85 installed, 1.84a does communicate with the CC box but 1.85 as downloaded does not. I copied chipcom.dll from the version 1.84a folder to the version 1.85 folder as was suggested by Joel Jacobs and it does fix the problem, V1.85 now will communicate with the CC box. Now to see if it communicates with the chassis under test. -- ******************************** Since 1972 * Jim Myers * Telrad Electronics * Fort Wayne Indiana * ******************************** ----------------------------------------------------------------------------- This Email List is Public.
