<P style="MARGIN: 0px">Hello,
<P style="MARGIN: 0px">I'm using the AX1500 in RS232. Is there any way that when you power on the board, the motor does not try to find the last position (0 posistion?) I do not want the motor to move on power on. I'm trying to use the Digital Inputs to turn off the Mosfets. I was trying to use the Output D as the input of Input F, so that when I activate the Output D, Input F sees 5V and turns on the mosfets. This is not working, I only get 2.5V on Output D no matter what command I send.
<P style="MARGIN: 0px">
<P style="MARGIN: 0px">What I need is a way so that the board does not move the motor on start up and only when I activate an specific Output or send a command. I prefer not to use any external relays or any other device. Can the output of Ouput C/D be combined with the input of Input E/F?
<P style="MARGIN: 0px">Thanks,

This feature is planned in the next version of the firmware. In this version, you can define a start position that is different than 0 that is reached at power up or upon signal loss. If you wish to try a beta version, please send us a note using the contact form <A href=" dev.roboteq.com/dev1/contactus.html " target=_blank> www.roboteq.com/contactus.html .
<P style="MARGIN: 0px">In the meantime, you should be able to achieve what you describe by connecting output c to one of the input and activate the Deadman function (MOSFETs are off while Input is floating high). Note that this will affect both channels at once.

<P style="MARGIN: 0px">Do you know when you plan to release the next firmware?
<P style="MARGIN: 0px">I've tried doing what you recommended me, but with no luck. I beleive my Output C is not working because it seems to be always open. No matter if it is open or close, it permits current to go through. The Input E also does not work. When I ground it, it stays as high. Input F and EStop work fine, but with them alone I cannot do anything. My Output D is stuck at 2.5V.
<P style="MARGIN: 0px">Is there any way of verifying if there is something bad with my board or what might it be?
