DC coder cable (lik-sang) and Dreamcast problem

[jang1080]

hi,
my problem is -> after connecting the coders cable from lik-sang to my DC theres a black screen while booting the console (with CD and without one), theres no difference if its connected to a PC or not. after removing the Cable from DC, the serial upload slave boots normal and i see blue borders. i use an RGB Cable for DC->TV.
the coders cable has the 47uf and the MAX3232.

thanks for your help
bye jang1080

I hope you use the serial slave and not the upload slave, i think you have a very messed up cable... isn't the rgb cable the one that goes into the serial port?
