ected to the receiver, the addresses are determined as follows:
▪
Address of the USB HUB: 100 (not visible)
▪
Address of the USB device connected to the first port of the USB HUB: 104
Above example shows a mouse that is connected to the USB port (Ch A1, Addr 2). The other device is a

However USB HUBs are supported by the receiver, only two devices are active at the same time in transparent
mode: the devices which are closest to the root address. If an active device is disconnected, the next valid
device (that is the closest to the root) will be active.
INFO:
Channel A1 and A2 are assigned to the devices automatically when a new device is connected.
Port Numbers
The port numbers of the USB HUB determines the priority of the devices. When more devices are connected
to an USB HUB, the USB port number determines the priority of the connected devices: the lower number, the
higher priority. This priority has an effect when the channels are assigned to the devices.
Blocked USB Devices
The USB blocking feature allows you to activate the desired devices when more than two USB HID devices
are connected to the receiver (two channels are available for USB extension). A typical example is shown in
