Operating and Controlling SWT3-41-U-T
Principles of Operation
This section covers the following topics: · Flexible SWT3-41-U-T Auto Switching Policy on page 19. · Online Meeting Systems Integration on page 20. · Routing IP-Driven Control Signals via Built-in Control Gateway on page 20. · Muting Extended Audio Signals on page 21. · Flexible Remote Buttons Control on page 21.
Flexible SWT3-41-U-T Auto Switching Policy
Set the USB host switching to connected USB devices policy to: · Manual Select a USB host manually and switching occurs whether a USB host live signal is present or not. · Auto Auto Switching selection is performed in either Last Connected or Priority policy.
In Last Connected policy: If a signal is plugged in this mode, SWT3-41-U-T will switch to it. If the signal on the current input is lost, SWT3-41-U-T automatically selects the last connected input.
The auto-switching delay depends on the configurable signal-lost timeout
In Priority policy: If a signal with a higher priority than the current one is plugged in this mode, SWT3-41-U-T will switch to it. When the input sync signal is lost for any reason, the input with a live signal and next in priority is selected automatically.
The auto-switching delay depends on the configurable signal-lost timeout. Inputs priority is configurable; the default setting is USB-C 1 USB C 2 USB 3 USB 4.
In both Last Connected and Priority modes, manually selecting an input (using the front panel, remote or web UI input select button) overrides automatic selection
See Setting the USB Auto-Switching Policy on page 30.

Routing IP-Driven Control Signals via Built-in Control Gateway
Remote IP connected clients can communicate and control (send commands, and receive responses and notifications) via the LAN:
· IP commands/responses via the LAN-connected SWT3-41-U-T and CAT-connected EXT3-UE-R LAN extension, to/from the EXT3-UE-R LAN-connected devices.
· Via the SWT3-41-U-T built-in and I/O control gateway: RS-232 commands, to control devices connected to SWT3-41-U-T, EXT3-UE-R and EXT3-U-R RS-232 control ports. The built-in control gateway sends the serial control commands (converted from the client received IP messages) to the locally and/or remotely connected serially controlled devices and distributes their received responses to all connected clients. Send or receive I/O digital triggers or detected triggers, to I/O control devices connected to SWT3-41-U-T and EXT3-UE-R I/O control ports. The built-in control gateway sends the I/O control commands (converted from the client received IP messages) to the locally and/or remotely connected I/O controlled devices and distributes their received detected triggers to all connected clients.
EXT3-UE-R I/O ports control and management via LAN is done via SWT3-41-U-T LAN connection and web-UI only.

Muting Extended Audio Signals
Sterio audio signal is extended from the switcher transmitter to both receivers, to allow easy audio and music distribution within the same space or separate rooms. Each extended audio signal can be independently muted, to enable a simple end-user control on the distributed audio signals.
See Muting the Extended Audio Signal on page 29.
Flexible Remote Buttons Control
Remote contact-closure buttons can be connected to the I/O ports, for easy end user control of device functions by button press and release operation.

Description
Set protocol permission.
The permission system works only if security is enabled with the “SECUR” command.
LOGIN allows the user to run commands with an End User or Administrator permission level. When the permission system is enabled, LOGIN enables running commands with the User or Administrator permission level When set, login must be performed upon each connection
It is not mandatory to enable the permission system in order to use the device
In each device, some connections allow logging in to different levels. Some do not work with security at all.
Connection may logout after timeout. Get protocol permission state.
