DOA AnOut1

DOA_AnOut1

Features:

• 16 channels
• 8 bit resolution
• uses DOA protocol
• primarily for d'Arsonval type of instruments
• other light loads can also be controlled with the built-in transistor outputs, eg to control cooling fan speed or dimmable lamps.
• open collector outputs, max 45V (or more, depending on transistor)
• software controllable refresh rate (usually called "PWM period")

Changes between Revisions:

Rev.0C	No functional changes. The outputs now feature a connector with more pins. The pinout on this connector thus changed. The odd-numbered pins all carry +5V, while the signals are on the even-numbered pins. Also added one capacitor, C2. Capacitor numbering changed as well.
Rev.0B	First public release.
