using a convenient graphical user interface (GUI) (see section 5).

3.2 Card-Edge Status LED
The status monitor LED is located on the front card-edge of the SME-1901/1911, and is visible through the front

flashing/steady illumination.
The chart shows how the various error conditions that can be flagged on the SME-1901/1911 affect the LED state.

means that the card is selected for
local control using the Densité frame’s
control panel. See Section 4 for
