Maho 650 - CNC 532 Philips

Does anybody know how the BTR Module from this series of CNC's working or were is located beaucause i have some communication problems and i can't locate this module .

I think that is somwhere in the Philips cnc 532, kic-532 module may be but nothing sure.

Can somebody tell me exactly where to search for it.

The interesting part is that when i load the entire program in to the machine all works fine, but if i try to use BTR function i'm reciveing an Baud Rate Error.

I've already verified all the machine constants, PC setings, and V24 transfer program settings all is like it should be, anything works fine even using transfer but with BTR it seems something is not right
