4. Device Concept
Event Manager +
The AND Operator
DIFFERENCE:
This feature is available from FW package v1.5.0b4.
The practical experience has shown that there is a need to examine more conditions (up to four) as follows:
if one of the set conditions becomes true (while the other conditions are fulfilled), then the set Action is
launched. For example, in a meeting room we have the following situation:
Signal is present on an input port,
▪
▪ A GPIO pin state becomes 'low' (by an external device).
If the two Conditions are present at the same time, the Action is launched. Just create the two Conditions into
separate Events, then create a third Event, select the two Conditions and define the Action.
See the Combine Links section for the settings in LDC.
Event Manager Variables
DIFFERENCE:
This feature is available only in UMX-TPS-TX140K and TX140-Plus models from FW
package v1.5.0b4.
A brand new area is opened by implementing the variables. You can create custom variables in number
or text format which can be used in the Event Manager. The variables can have the following properties/
methods:
Numeric (integer) type with min/max value setting, or string-type (determined automatically)
▪
Increment/step the numeric value,
▪
▪ Value-dependent case operations,
▪ Reading and storing the value of an LW3 property into a string or a numeric variable.
The defined variables are stored in a non-volatile memory and the value is kept in case of a reboot. The
new opportunities allow creating a monitoring/controlling system without connecting an additional control
processor.
See the Variables section for the settings in LDC.
Condition Trigger
DIFFERENCE:
This feature is available only in UMX-TPS-TX140K and TX140-Plus models from FW
package v1.5.0b4.
This improvement in the Event Manager works as if a condition is detected. When a complex control system
is built, a Condition may trigger numerous Actions. A typical example is when a system is powered on and
the 'ready-to-use' state has to be loaded. In this case, there could be many actions which are based on the
same condition. In order to reduce the number of the commands, you can trigger one 'key' condition, which
could start the whole process.
See the Condition Triggering section for the settings in LDC.
Applied firmware packages: (UMX-TPS): v1.5.0b4 | (WP-UMX-TPS): v1.4.0b8 | (FP-UMX-TPS): v1.4.0b8 | LDC software: v2.5.6b2
UMX-TPS-TX100 series – User's Manual
4.14. USB Interface (KVM Function)
DIFFERENCE:
Only the UMX-TPS-TX140K model is supplied with USB port.
UMX-TPS-TX140K model supports HID-compliant (Human Interface Device) devices to transmit USB signal
between the source and sink devices. The UMX-TPS-TX140K transmitter connects to the controlled device
(e.g. PC) and the controlling devices (e.g. computer mouse, keyboard, touch panel) are connected to the
compatible receiver.
ATTENTION!
The compatible receiver for the USB KVM extension is HDMI-TPS-RX220AK.
The device can be controlled over front panel USB mini B-type connector. This interface only supports LW3
protocol. The interface can be also used to establish a connection to the LDC software.
ATTENTION!
Only HID-compliant devices are supported by the extenders. Non-HID devices (USB sticks,
webcams, etc.) will not be working with the UMX-TPS-TX140K.
ATTENTION!
USB HUB devices are not supported by the UMX-TPS-TX140K transmitter.
Technical background
The same USB data is transmitted on the RX side which is received on the TX side. The content of the
transmitted packets are unknown to the Lightware infrastructure so the data is not modified by any means
during transmission.
Key Features:
▪ Supports all HID-compliant devices.
Driver software for all connected USB devices has to be installed on the controlled computer. The
▪
connected mouse and keyboard will be detected as a new hardware in the operating system.
USB KVM Function - Example
The Concept
The PC is the sink device for the USB KVM function. The HDMI-TPS-RX220AK receiver is connected to the
TPS output of the transmitter via CATx cable. The keyboard and the mice are connected to the receiver at
the end user side.
There is no restriction on the USB-HID devices if the driver is installed on the connected computer the USB
KVM signal is transmitted to the receiver without any limitation.
