hi,

is it possible to directly link (with or without a max 232) the Parallax Servo Controller (Serial) to a pc?

and how should i wire this connection?

thanks?

    The older Parallax servo controller used USB

    There is an RS-232 interface schematic for the PSC on the following froum page. Take care.

    and how would i connect this directly to a another (non parallax) microcontroller?

    I'm not sure I follow you. Your original question was how to connect the PSC Serial to a PC serial port. What are you trying to connect to what in the second question?

    well i was thinking of connecting it directly to a simple serial port of a microcontroller

    so a ttl serial port and not a real serial line, how can i do this?

    Theoretically, you could directly connect the PSC to any TTL serial port on a microcontroller. Practically, it's safer to include a 220 Ohm resistor in series with each signal line. This will limit the "fault" current in case there's a programming error that accidentally makes a receive line into a transmit line.
