According to the R&D team in France, support for the CCA634 adaptor was added to the Sepam 20 and 40 platforms in June 2006.

If the serial number of your Sepam 20 or 40 relay is older than this, then you may not be able to use the CCA634 adaptor, as some new hardware changes were introduced in 2006.
