d. Click the Add Driver button. The selected manufacturer and model names are displayed in the Selected MediaLink [Serial or IR] Driver field.

If you change your mind about the driver you selected, click Remove Driver, and repeat steps 4b through 4d to add a different driver.

e. Click Next. The Assign Commands To Buttons screen opens, displaying a diagram of the buttons on your MLC 52 and a list of commands that are available with the selected driver.

5. (Optional) On the Assign Commands To Buttons screen, you can assign up to four commands to any of the six MLC buttons reproduced in the diagram that do not already have commands assigned.

When the Assign Commands to Buttons screen opens via the wizard, some of the buttons may already be programmed with commands; for example, most drivers have power on and power off commands programmed on the two Display buttons, which are labeled On and Off on the wizard screen. On the standard MLC (not the VC model), many of the drivers also have commands programmed on the two Vol buttons to increase/decrease the display device’s volume. Because commands have been added to these buttons, red triangles appear in their upper-left corners. You cannot remove these preprogrammed commands from the volume and power buttons or add commands to them using the wizard. (You can add commands to them using the configuration software directly. See “Configuring using the Windows-based configuration program” on page 5-19.)

Buttons that are labeled PC, Video, DVD, VCR, or blank are left unprogrammed. You can add, remove, or change commands on these buttons.

Alternatively, you can click Skip to go to the next screen, and complete the wizard without adding any commands at this time. (You can add commands later from the Windows-based configuration software.)

The buttons are prelabeled. You may wish to change these labels if they no longer reflect the commands you added to the buttons. To change the button labels, you must access the Windows-based configuration software directly. (See “Assigning functions to buttons” on page 5-23, for more information.)
