Re: FT-857 RTS/DTR CW Sending

 

Yes right , in DB9 case there is plenty of place for components ¡­. after that use an USB/ RS232 convertor having all command pins for RS232 ( not only RX and TX )

Good luck

?Dan-san,

I¡¯ll try the schematic.

One NPN TR and one resistor can be set in the DB9 connector case, I guess.

Thanks a lot.
