Does anyone know the maximum reach of a serial cable and usb cables?
I have a pc across my bedroom and between my serial dongle and radio I would like to start getting digital modes going. Sorry for the basic questions.
In general, the max spec for a USB cable is 16 feet. I don't remember the RS232 spec length, but it would certainly depend on the driver chip. full +-12v will certainly go farther than +5-0 TTL shortcuts.
