AMX 8400 was unable to connect with the wireless router. customer dismantled and installed system from one site to another. after that they were unable to connect the AMX 8400 with the wireless router.
As the AMX touch panel was unable to connect with the wireless router i wanted to open the protected setup by pressing the 4 key on the left side and menu key downward at the same time. as mentioned in the document it should enter into protected setup after 3 settings but it did not. so i was not able to reconfigure it as setup menu was not opening. i aslo try to restart the system by removing the batteries but still the same problem exists.
AMX 8400 was unable to connect to the wireless router as some configuration settings meant to be changed but we were not able to get into the protected setup menu as no button on the touch panel was working.
if this case occurs touch panel is already connected to the wireless router then try to telnet and reset the touch panel. and if the still problem exists replace the AMX as its faulty. and if not connected to the wireless router then try to restart and then check. if not ok replace the AMX.
