I have 10 Itech amplifiers all of them conected to the system architect 1.5. However, there´s an Itech6000 that I can´t conect because its firmware version is 184.108.40.206 and its IP address seems to be 0.0.0.0. Therefore, Everytime I attempt to update the firmware I get an error message that says it can´t work with and 0.0.0.0. IP adress. What should I do?
