I am considering the AX3500 for a project, but I have a question about the interface.
I understand the unit can use a RS232, but does the RS232 stop there?, let me explain, need a dual motor speed controller , but also some other things like a RS232 relay board for other functions, does the AX3500 have pass through RS232?

<P style="MARGIN: 0px">I am not quite sure what you mean about pass through rs232 but I don't believe you will be able to share a serial port with another device.

Thanks for the reply Cosma, I think I figured out how to accomplish my requirements without the rs232. I looked at the Roboteq/Via rover project, then looked further into the VIA part, the computer has additional USB ports and I found a source for USB relay boards, not to pricey either.
