[1000mp] MAX232 replacement.... not a big deal.

[PA5CA Frans]

Dear Guido,

Thanks for the excellent input for the CAT users however I need to make one
little remark on the schematics.

In your drawing you are feeding the OPTO"s from the RS232 port. we know from
experience that some RS232 ports do not deliver enough current, so I
designed an interface which ccan handle that phenomenon.

It is a pitty that I can not up-load schematics so I 'll  place modified
schematics on the PA6Z home page.



Please note that you may read the text at
http://www.pa6z.nl/PROJECTS/INTERFACE_v2/interface_v2.html first.

After reading this part go to the following link with the modified
schematics for the FT1000mp.xx

The URL will be www.pa6z.nl/ft1000mp.html



Good luck... and have fun.
