Kramer Electronics Ltd.
Coupled or Individual AV+USB Switching
SWT3-31-HU multi-signal switching of any of the inputs to the AV output and connected USB
devices, is configurable to use one of the following operation modes:
• USB follows AV coupled routing ( ) – Selecting an AV input, routes the AV signal to
the AV output and connects, in parallel, the input-associated USB host with the
connected USB devices.
• USB signal individual routing ( ) – Selecting an AV input, routes the AV signal to the
AV output only. The USB host can be independently selected to connect with the
connected USB devices (see Individual USB Host Routing.
See Routing AV and USB Host Signals on page 22
This is very useful in hybrid sessions, for convenient switching between multiple presenters
using either their BYOD laptops and/or connected space PC devices.
.
Flexible SWT3-31-HU Auto Switching Policy
Set the switching policy to:
• Manual – Select an input manually and switching occurs whether a live signal is present
on the input or not.
• Auto – Auto Switching selection is performed according to either the Last Connected or
the Priority policy.
In Last Connected policy:
If a signal is plugged in this mode, SWT3-31-HU will switch to it.

Routing IP-Driven Control Signals via Built-in Control Gateway
Remote IP connected clients can send from the LAN, via the SWT3-31-HU built-in control
gateway, CEC, RS-232, I/O and IR commands, and receive responses and notifications, to
control devices connected to SWT3-31-HU HDMI-CEC, RS-232, I/O and IR control ports. The
built-in control gateway sends the control commands (converted from the client received IP
messages) to the connected controlled devices, and distributes the responses received from
the connected controlled devices to all connected clients.
Figure 7
shows the SWT3-31-HU built-in control gateway connection. The Kramer Control
controller is connected to the switcher via LAN, sends IP commands to the switcher control
gateway over the LAN connection, to send control messages to, and receive control
responses from:
• The touch TV connected to the switcher via the IR and/or HDMI (CEC) ports.
• The PTZ Camera connected to the receiver via the RS-232 port.
• The Occupancy Detector & Select In Button connected to the receiver via the I/O ports.

Routing AV and USB Host Signals
SWT3-31-HU enables switching any of the inputs to the output in one of the following
operation modes:
• USB follows AV coupled routing ( ) – Selecting an input, routes the HDMI signal to the
output and associates the USB devices to that selected USB host.
• USB signal individual routing ( ) – Selecting an input, routes the HDMI signal to the
output. The USB host can be selected separately from any of the other inputs.
Kramer Electronics Ltd.
Individual USB Host Routing
In the following example, USB routing does not follow video, so you can individually select the
AV signal on input 3 and the USB signal on input 1. This means that the HDMI input 3 AV
signal is routed to the output and the USB devices are associated with the USB-C host (Input
1).

Configuring a Digital Input I/O Type
The Digital Input trigger mode reads the digital input of an external sensor device that is
connected to the I/O port. It detects High (upon passing Max threshold from Low state) or Low
(upon passing Min threshold from High state) port states according to the user defined voltage
threshold levels.
To configure a digital input I/O type:
1. On the GPIO page, select Digital Input next to I/O Type.
The Digital Input options appear (Figure 31
).
2. Select one of the following for the Pull-up resistor setting:
Disabled
Suitable, for example, for a high temperature alarm that exceeds the maximum voltage
threshold. When the pull-up resistor is disabled, the port state is low and to be triggered
it must be pulled high by the externally connected sensor.
Enabled – Detection of an open circuit as High, or a short to ground as Low.
This is suitable for example, for a pushbutton switch (connecting one terminal of the
switch to ground, and the other to the input) or for an alarm closing a circuit that
activates a series of actions. When the pull-up resistor is enabled, the port state is high,
and to be triggered it must be pulled low by the externally connected sensor.
3. Set the Threshold VDC Low and High Range (threshold voltage at which the port
changes state).
4. Click Read to refresh port status information.
5. Click SAVE.
Digital input I/O type is configured.

The port can be used for controlling devices that accept a TTL signal such as for
powering LEDs. The voltage output is TTL positive logic: high: >2.4V; low: < 0.5V.
When the pull-up resistor is enabled, the port state is high. For the state to be low, you
must select Low for the Current Status.
Pullup resistor Disabled:
The port is used for controlling external devices such as room or light switches. The
external source device determines the voltage output; the maximum voltage is 30V DC
and the maximum current is 100mA.
When the pull-up resistor is disabled, the port state is low. For the state to be high,
select High for the Current Status.
5. Click SAVE.

Protocol 3000
Kramer devices can be operated using Kramer Protocol 3000 commands sent via serial or
Ethernet ports.
Understanding Protocol 3000
Protocol 3000 commands are a sequence of ASCII letters, structured according to the
following.
• Command format:
• Feedback format:
• Command parameters – Multiple parameters must be separated by a comma (,). In
addition, multiple parameters can be grouped as a single parameter using brackets ([
and ]).
• Command chain separator character – Multiple commands can be chained in the
same string. Each command is delimited by a pipe character (|).
• Parameters attributes – Parameters may contain multiple attributes. Attributes are
indicated with pointy brackets (<…>) and must be separated by a period (.).
The command framing varies according to how you interface with SWT3-31-HU. The following
figure displays how the # command is framed using terminal communication software (such
as Hercules):
