Each channel also has its own error bit indicators. The boxes that have a red background
color indicate an error that is currently detected and counted. A green background will
indicate that the particular error is set to be counted, but that the error is currently not
detected. Errors that are not to be counted (i.e. set to Ignore) will be presented as the error
bit name on a gray background color (no example shown here), regardless if the error is
currently detected or not. Error types that are not supported for that particular channel will
be shown as blank boxes with gray backgrounds. Most web browser will expand the boxes
that contain text at the expense of these blank ones, as the examples above show.
4.2 On front mounted LEDs
Table 2: LED states and what they mean
The LEDs on the board are not labeled in silk screen. Users familiar with the Flashlink
range will know that the upper LED (closest to the red handle) is the status LED. The order
of the rest of the LEDs corresponds to the order in the table above.
Note that the configuration of the Expected video format will influence the way
the LEDs behave.
The “Don’t care” condition mentioned in the table above
refers to the “Expected video format” settings, and only those channels
assigned a specific video format will affect the LEDs. Conversely, setting all
channels to “Don’t care” will result in LED 3 and LED 4 always being green,
even if all video signals are missing.
4.2.1 Exceptions/special conditions for the LEDS
The locate command will make all four LEDs blink on and off synchronously to quickly
identify the module in a larger installation. The condition of the card is not otherwise
affected by the command, only the appearance of the LEDs will change. The LEDs return to
their normal states and functions after the special locate condition has timed out.
