6.7.2. USB tab
MODEX devices are able to extend two USB 1.1 and/or USB 2.0 devices from the
transmitter to the receiver that are compatible and in line with USB HID standard. Typical
supported USB devices are:
USB mouse and keyboard,
Smart Card (reader).
Typical application is when a computer located at the transmitter is contro
lled at receiver’s
side by the connected keyboard and mouse via USB. Certain touch monitors fulfill the USB
HID standard, which can also be connected.
Connected USB devices and the status are displayed on the panels:

Device states
Disconnected: No device is connected to the USB port and no device is emulated
to the computer.
Enumerated: USB device is connected and install is in progress.
Connected: USB device is connected to the receiver and emulated on the
computer.
Suspended: Keyboard and mouse functions are emulated by the extender and no
USB enumeration occurs while operator switching. A computer is not aware when
the device has been changed. When the state is Suspended, device is
disconnected from the extender however it is still emulated to the computer.
6.8. Event manager
The Event manager was developed because of user needs to display internal events (such
as signal present or HDCP active) on GPIO ports, and controlling the device with GPIO
inputs instead of front panel buttons. However the Event manager can be used without
GPIO module, too. The function is very comfortable when the device is built under the desk
and the front panel pushbuttons and LEDs are not accessible.
Basically the Event manager can be configured to detect LW3 CHANGE messages, and if
the condition (the given change message) appears, the event will be fired. The device will
perform an action (send out a preprogrammed LW3 SET or CALL message to itself). E.g.
the desired setup is that after the input signal has been present on the VGA port, the level
of GPIO1 pin is changed. The settings can be done via the LDC in the Control/Events tab,
or by LW3 protocol commands, see section
