No, I'm talking about whatever is sent between the flash and the body to control TTL flash operation. I've been lead to believe that prior to the advent of P-TTL, Pentax had two ways of doing this, and that one involved simple analog signalling, while the other was some sort of digital protocol. I was wondering which the Vivitar 6000 (which is a "dedicated" TTL flash) might be using.
