Always switch off the power to each device before connecting it to your KRAMER SWT3-41-H. After connecting, connect its power and then switch on the power to each device.

1. Connect HDMI sources: Connect your HDMI sources (e.g., laptop, desktop PC, document camera, set-top box) to the HDMI IN connectors.

2. Connect HDMI output: Connect the HDMI OUT to an HDMI acceptor, such as a display.

3. Connect audio output: Connect the AUDIO OUT to a balanced stereo audio acceptor, for example, Kramer Tavor 5-O active speakers.

4. Connect remote buttons: Connect remote contact-closure buttons to the I/O terminal block connectors and configure their function (e.g., to select an input).

5. Connect for serial control: To serially control the display, connect the RS-232 port to the display. You can then send serial commands from a LAN-connected Kramer controller (e.g., SL-240C) to the display via the control gateway.

You can connect to the KRAMER SWT3-41-H via its RS-232 3-pin terminal block connector. To connect from a standard RS-232 9-pin D-sub serial port on a PC/controller, follow these pin connections:

• Connect Pin 2 (Tx) from the D-sub port to the TX pin on the SWT3-41-H RS-232 terminal block.

• Connect Pin 3 (Rx) from the D-sub port to the RX pin on the SWT3-41-H RS-232 terminal block.

• Connect Pin 5 (Ground) from the D-sub port to the G pin on the SWT3-41-H RS-232 terminal block.

The KRAMER SWT3-41-H offers the following switching policies:

• Manual: Select an input manually. Switching occurs whether a live signal is present on the input or not.

• Auto: Auto Switching selection is performed according to one of two policies:

– Last Connected policy: If a new signal is plugged in, the SWT3-41-H will switch to it. If the signal on the current input is lost, the device automatically selects the last connected input. The auto-switching delay depends on the configurable signal-lost timeout.

– Priority policy: If a signal with a higher priority than the current one is plugged in, the SWT3-41-H will switch to it. When the input sync signal is lost, the input with a live signal and the next in priority is selected automatically. The default priority is HDMI 1 -> HDMI 2 -> HDMI 3 -> HDMI 4, but this is configurable.

In both Last Connected and Priority modes, manually selecting an input (using the front panel, remote, or web UI) overrides the automatic selection.

The KRAMER SWT3-41-H front and rear panel buttons enable the following actions:

• Selecting an INPUT.

• Using the VOL buttons to increase or decrease the volume.

• Using MUTE to mute/unmute the audio output.

• Turning the display on or off via the DISPLAY ON button or sending on/off commands that are configured via the UI.

• Resetting the device to its factory settings by pressing and holding the recessed RESET button on the rear panel while connecting power.

To connect the KRAMER SWT3-41-H directly to a PC, use a crossover cable with RJ-45 connectors. This type of connection is recommended for identifying the device with its factory configured default IP address.

After connecting the cable, configure your PC’s network settings as follows:

1. Click Start > Control Panel > Network and Sharing Center.
