Qik 2s12v10 error trying to communicate

I have set up my “Qik 2s12v10” controller according to the user manual and as shown in the photo here:
I am running Ubuntu 10.04 on a desktop computer and have the motor controller hooked up to the /dev/ttyS0 serial port on this machine. I am trying to send individual commands to the motor controller (such as the simple “0x8D” command). The problem is as follows:
I am able to successfully open a terminal (“Terminal Ready”) in picocom, however, when I start typing (literally any key I press), the error light comes on and no text is printed in the terminal.
Is my setup bad? Or perhaps is there some configuration step that I am missing?

Thank you for your help.


Most terminal programs send ASCII encoded strings, so you are probably sending ASCII strings to the qik rather than serial command bytes. ASCII is not supported by the qik; it only accepts raw, binary bytes. You might try using this bash script for sending serial commands to our Maestro as a starting point for sending serial bytes to the qik.
