Hi, I've just rewired the messy cables. After powering up the Controller (Green LED steady, Red LED blinking) then I noticed the KP04 displaying "Updating text..." while I can hear buzzing sound on the speaker. After it completed, when I tried to press the key, KP04 displayed "Keypad not polled"! Can you pls advice how to solve this problem? Best Regards,
