Example (video input ports on a UMX-TPS-TX140)
The priority values have to be assigned to each input port which are desired to use. The
followings priority settings will be used during the explanation of this mode:
Priority
0
1
2
3
4
Input port
P3
DP
P2
HDMI
P4
DVI-D
P1
VGA
P5
DVI-A
After an event the device always checks the port with the highest priority, P3 (DP). If there
is a valid signal on it, P3 will be selected. If there is no valid signal on DP input port the
device checks the following port with priority 1, P2 (HDMI). If there is a valid signal on it,
P2 will be selected. If there is no valid signal on HDMI input port the device checks the
following port with priority 2, P4 (DVI-D). If there is a valid signal on it, P4 will be selected.
If there is no valid signal on DVI-D input port the device checks the following port with
priority 3, P1 (VGA). If there is a valid signal on it, P1 will be selected. If there is no valid
signal on any of the checked input ports, the No sync-screen state will be checked. if the
state is Off, there will be no Audio/Video transmission, otherwise No Sync-screen will be
displayed.
Port priority settings
Autoselect priority settings can be changed via the LDC surface, see section
, or by protocol commands.
Special features
The same priority number can be set to different ports. In this case the input port with the
lowest port number will have the highest priority among them. E.g. setting the priority of P2
(HDMI) and P3 (DP) to “0”, the HDMI input port will have higher priority since P2 is lower
than P3. Ports can be skipped from the priority list by giving the lowest value: priority 31.
5.4. IR interface
IR receiver can sense IR light (e.g. emitted by a remote controller) and send electrical
signals to the IR transmitter. The IR transmitter unit processes the electrical signals and
emits IR light toward the controlled device (e.g. projector). IR OUT receptacle accepts only
the IR transmitter and IR IN receptacle accepts only the IR receiver. IR accessories are not
interchangeable.
IR signal from the IR input is transmitted to the receiver or input board and vica versa.
Info: Direct line of sight is required between IR transmitter and the controlled device (e.g. Blu-
Ray or DVD player) and the same is valid for the IR receiver and the controller device (e.g.
remote controller).
5.5. General purpose input/output ports (UMX-TPS-TX130 and TX140)
Certain models have 7 GPIO pins, which operate at TTL digital signal levels and can be
controlled by both LDC and LW2 / LW3 protocol commands.
Output pin state can be set with specific command.
Input pin state can be queried, and a notification is sent from the device, if the state
is changed.
As a special function, the GPIO pins would act the same way as video select, audio select
and show me buttons. Using the GPIO pins in conjunction with the Event manager gives
many functions. See more details in section
Info: GPIO control is available in Firmware v1.0.1 and above.
