What voltages can I use on the Tau2 and Quark2 serial port?

Tau2 and Quark2 cameras can accept 5V logic levels on the serial port input interface without any problems. Full RS-232 voltage levels can also be used directly. The cameras will only transmit with 3.3V CMOS logic levels. The Tau2 cameras will automatically detect and use the correct "sense" between digital serial signals and (logically inverted) true RS-232 signals.
