9.4. The Tree Structure of the UBEX Matrix
When the UBEX matrix builds up and starts to operate, the individual endpoints and the MMU cease to be
individual devices, but the whole system becomes one big tree structure including all UBEX devices which
are the part of the matrix.
When you connect one of endpoints you always will reach the LW3 tree of the MMU. The endpoints can be
controlled over the MMU only.

9.4.2. Endpoint ID Calculation
The endpoint devices of the matrix are listed under the /SYS/ENDPOINTS node by the MAC address. The
formula is the following:
MAC address of the endpoint
The last 6 characters of the MAC
address
Endpoint node under /SYS
A8:D2:36:00:39:A1
0039A1
UBEX0039A1
Where the path of a LW3 command/method/etc contains a UBEX endpoint, the following parameter refers
to it:

9.4.3. Stream ID Calculation
All endpoint devices which are connected to the UBEX matrix got a logical device ID generated by the MMU.
DEFINITION:
Logical device ID
means the MMU assigns a number to the endpoints ordered by the discovery.
For example the first endpoint gets the 1 (appears as X1 under the DEVICEMAP), the second one the 2
(appears as X2).
The stream ID is based on the logical device ID. The registered endpoint can be transmitter, receiver, or
transceiver. All transmitters have two inputs, all receivers have two outputs, and all transceivers have one
input and one output. The first discovered endpoint gets the X1 logical device ID, the HDMI port 1 of the
endpoint is always the 01 number, the HDMI port 2 is always the 02 number. If the endpoint has input port
(TX / TRX), it is signed with
S as Source
, if it has output port (RX / TRX), it is signed with
D as Destination
. The
formula is the following:
<Port_type><Logical_device_ID><Port_number>
Two endpoint devices cannot be assigned to the same logical device ID. The number is always calculated
for the endpoints independently from the operation mode.
INFO:
The logical device ID (and the order of the endpoints) can be changed by the LDC software (see
the details in the
section) or by LW3 protocol command (see the details in the
Endpoint to a Logical Device ID
section).
INFO:
The operation mode (TX, RX, or TRX) can be changed for any endpoint. See the related LW3 protocol
section.
