4.9.6 Video and USB HID - Matrix Connection - Dual-Head Extender Modules
When extender modules are connected to a matrix, the LEDs behave differently depending on whether there is a link
connection between the CON Unit/CPU Unit and the matrix, whether the CON Unit is switched to 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, when the OSD is opened, only Video-only
Access is present, or Full Access is present in sharing operation without current USB HID control, or the CON Unit is
not switched to the CPU Unit.
