FAQs
When connecting locally through the iBridge app or IBR-ITAB tablet, why is the keypad displaying "NULL"?
Check two items:
(1) Ensure the IBR-ZREMOTE jumper J4 is installed (J4 is located at the top right of the top PC board, next to the larger jumper J3).
(2) Check that the second CAT5 network cable is connected to the socket located on the right side of the IBR-ZREMOTE module.
