arduino victor 884 and a cim

[Crawler]

pullup resistors and solenoids, I read its best to use servo coding even for a cim, but i just cant say i understand how these relate. Solenoid = victor? what would the pullup resistor do (im reading something about returning it to a state if no input is read, maybe to read that the joystick is let off?)? If this is what works for a victor and cim (i guess it doesnt matter what type of motor right?) then maybe it would be best just to look at your wireing diagram, or if you want i can create one for what i have if you would like.

Thanks,
Nick
