Bad Software Message

Please help… My Fargo Maestro 100 sends “Bad Software” message everytime i power it up. The LED indicator is continously Blinking. I try to send an AT command but no response from the modem instead it echoes back what i type. What should i do?

Thanks in advance.


Did you update the core firmware? Or did you import the module from another country which might require a different software?

Best Regards,
