Required devices: Remote controller to be checked, HDcom to be checked, PC, and serial cables.
Connect the devices following the DIAG check procedures, and then, start the DIAG mode.

Command: TEST_REMOCON
Press the buttons on the remote controller and confirm that the device receives the Data Code that correspond to each key num-
bers.

Key numbers for each remote controller IDs are shown in the Data Code table.

Example: Select 1 as the remote controller ID, and then, press the Video Out On/Off key.
"01" appears on the PC screen.
Please push # key when the measurement ends.
