Routing IP-Driven Control Signals via Built-in Control Gateway
Remote IP connected clients can send from the LAN, via the SWT3-41-H built-in control
gateway, CEC, RS-232 and I/O commands, and receive responses and notifications, to
control devices connected to SWT3-41-H HDMI-OUT, RS-232 and I/O 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 8
shows the SWT3-41-H 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 display connected to the HDMI output (CEC) and the RS-232 port.
• The Occupancy Detector & Select In Button connected to the switcher via the I/O ports.
Built-in control gateway activation, activation of the associated control ports and their
attributes (such as the CEC logical address of the control gateway), as well as manual
commands testing operation, is done via SWT3-41-H control gateway webpages (see
Control Gateway Properties on page 28).

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.
Configuring a Digital Output I/O Type
To configure a digital output I/O type:
1. On the GPIO page, select Digital Output next to I/O type.
A warning message appears.

Make sure that the current in this configuration does not exceed 100mA.
3. Click OK. The Digital Output options appear.
Kramer Electronics Ltd.
Figure 31: GPIO Settings Page – Digital Output I/O Type
4. Select one of the following for the Pull-up resistor setting:
Pullup resistor set to Enabled:
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.
Digital Output I/O type is configured.

Configuring an Analog Input I/O Type
When selectin the Analog Input I/O type, the port is triggered by an external analog device,
such as a volume control device. The trigger is activated once when the detected voltage is
within the 0 to 30V DC voltage range.
To configure an analog input I/O type:
1. On the GPIO page, select Analog Input next to I/O type.
2. Enter or use the arrows to scroll to a value (1–100) for the Maximum reported steps.
This value is the number of steps that the analog input signal is divided into. To calculate
the voltage of each step, use the following formula:
Voltage of one step = 30V / number of steps.
3. Click SAVE.
Analog input I/O type is configured.

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 SWT3-41-H. The following
figure displays how the # command is framed using terminal communication software (such
as Hercules):
