4.9.3 Video and USB HID - Point-to-Point Connection - Single-Head Extender Modules
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 transmission rate
(RBR/HBR) a video signal is transmitted, or whether a USB HID connection exists.
The following tables show the respective LED states/colors (upper LED (6) and the lower LED (5)) of the CPU Unit
and CON Unit for the respective situation.
For information about the transmission rates, see chapter 13.1.1, page 67 and chapter 13.1.2, page 68.
The USB connection is missing, when the command mode is started, or when the CON Unit currently has no
USB HID control with shared operation of a redundant CPU Unit.
