I have a problem with my Kelly KLS7250D (http://kellycontroller.com/kls7250d24v- ... -1337.html). I think I briked it by changing the motor spin direction via the PC interface while the motor was running. Now no RS232 communication is possible and the controller does not move the motor. After having a conversation with Fany from Kelly the can't help me because my controller ran out of warranty and I told them that I opened the controller. When I opened the controller I saw two JTAG interface headers.
I think by reprogramming the firmware the controller can be unbricked.
- So what programming hardware do I need to flash a new firmware via the JTAG interface?
- Can someone provide me the firmware or read it from their controller?
- Is there an other possibility to unbrick the controller?
