2 Status LED 2 USB-HID and video
1 Status LED 1 USB-HID and video
2 Status LED 2USB-HID and video
When extender modules are connected directly, the LEDs behave differently depending on whether there is
a link connection between the CON Unit and the CPU Unit, whether a video signal is present, at which
resolution a video signal is transmitted, or whether a USB connection exists.
The following tables show the respective LED states/colors (upper LED (2) and the lower LED (1) of the
CPU Unit (column 2) and the CON Unit (column 3) for the respective situation.
