I got an SPI fiber laser (50W, GEN4, SP 050 A-RM-Z)) but manual is missing...

Trumpf, which is the new owner of SPI, doesn't seem to be really aware of those lasers. The SPI website keeps asking for a password but never send a link to register ... I can't fire it up !
Does anyone know these lasers or have a manual so I can power on (I don't know the signals required by the interface board) ?
Thanks a lot !

Greatings,
Fabrice
