My reason for asking this question was told "C-Series ex-link is on TTL-Level (0V to +5V) while your PC operates at RS232-Level (-12V to +12V) so your cable has to have at least some kind of Voltage-level shifter."

Hard for me to believe that Samsung would make Smart TV that could be damaged if someone used a standard VGA cable to connect it to a PC.

But you never can tell and would rather be safe and ask.

Thanks
