Problem with the SMCI35 motor controller

Former Member

Recently, I purchased a few Nanotec's components from Farnell. I'm having a problem on detecting the controller.

 

I've got the SMCI35 controller, ZK-RS232-USB-3.3V cable converter, charging capacitor z-k4700/63, and a linear actuator L4118S1404-T5X5. After I connected all components to the power supply, I tried to run the linear actuator, however, the NanoPro v1.70 couldn't detect the controller. I've checked all the wiring, and I can't find any error in it. I can't find any answer on the troubleshooting page nor the controller manual.

 

So, I was wondering am I missing any component? Or I made a mistake in components selection? is there a missing driver for the connecting cable?

 

Please help me to solve this problem.

 

Thank you very much.

    Hi Jamie,

     

    I am trying to connect the motor controller together with the NanoPro software that comes with it, and also the linear actuator. The end result is that I will be able to control the speed of linear actuator from the NanoPro interface. I've used the cable to connect my laptop to the controller, then the controller is connected to the power supply by placing a charging capacitor in between, finally I connected the linear actuator according to the pin order in the manual.

     

    I followed every single steps in the manual, but my laptop still unable to detect the controller.

     

    What are the possibilities that cause the problem?

     

    Thank you

    No idea why Jamie has put this in Linear Technology Group (it doesn' admit to using any of their parts).

     

    @Alex - do you have a scope ?

     

    In your place I would check that there is activity on the SMCI35 serial RX pin when the PC software is trying to find the board.

    Did you spot the dire warning about blowing the serial interface if the PC is plugged in when you make the USB connection ?

    Did you check the firmware download document (loss of firmware is listed as  a reason for the board not to talk to the PC.)
