Q: 1. I always get error messages when the PC program starts
2. Any action (read, check, write, etc.) to the programmer fails
A: The PC software can only be used when the MCP-x51 USB interface has completely been detected and installed by the operating system. Therefor the start up sequence is as follows:
  • Connect the USB cable to the PC and the MCP-x51.
  • Connect the power supply to the MCP-x51.
  • Turn on the MCP-x51.
  • Wait until the USB detection is complete. This can take up to 15 seconds and differs per operating system and PC speed.
  • Start the PC application.
  • Q: I keep getting the message "Error 49 USB <any action> Command Fail"
    A: It is not needed to turn off the power of the programmer to change a component in the ZIF socket. When the Action LED is OFF, and the PC software is not communicating with the programmer, any IC in the ZIF socket can safely be removed or replaced.
