Understanding Error Messages

råÇÉêëí~åÇáåÖ=bêêçê=jÉëë~ÖÉë

Please note the following important rules regarding error messages.

LOS:

Slot 1

Input 3

Invalid:

Slot 1

Input 2

Note	For the input connectors on the NIC and UIC, the “red” error
	conditions only occur if the input has been mapped to the
	panel, and the signal was previously OK.

•LOS (loss of signal): On occasion, you can experience LOS (loss of signal) — typically due to a poor video connection or computer connection.

If this condition occurs:

~A red Error button appears in the upper left corner of the Touch Screen.

~The input’s BNC turns red in the rear I/O view.

~The input’s Programmable Display turns red.

During an LOS condition, if the user preference “Black on Invalid Video” is turned on, black will replace the lost output video. In Chapter 5, refer to the “User Preferences Menu” section on page 254 for details.

•Invalid Video: On occasion, this message can appear if the input format does not match the selected native resolution, or if the input signal is not locked to the system’s video reference input.

If this condition occurs:

~A red Error button appears in the upper left corner of the Touch Screen.

~The input’s BNC turns red in the rear I/O view.

~The input’s Programmable Display turns red.

Note	For both LOS and Invalid Video conditions, you can also
	navigate to the Input Menu, and check the color of the
	connector in question to verify the physical input’s condition.

Error

Reporting

On

If one of these types of error occurs, you have several options:

•Leave the Error button and red Programmable Display as is.

•Press the Error button to display a pop-up with options for more information. The pop-up also has a {View Error Info} button, which when pressed, takes you to the View Errors Menu.

•Navigate to the Input Menu, and note the red BNC that is experiencing the error. Press the {Error Reporting} button to toggle error reporting Off for the selected input. When Off, the red error message turns off, the Programmable Display returns to green, and the error is removed from the list in the View Errors Menu. In this mode, however, the connector remains red.

Note	The {Error Reporting} function works on a connector by
	connector basis. You can have reporting on for one
	connector, and off for another.
