Operating and Controlling SWT3-41-H

Principles of Operation

This section covers the following topics:

Flexible SWT3-41-H Auto Switching Policy on page 9.

Routing IP-Driven Control Signals via Built-in Control Gateway on page 10.

Flexible SWT3-41-H 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, SWT3-41-H will switch to it.
• If the signal on the current input is lost, SWT3-41-H 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-H 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 HDMI 1→HDMI 2→HDMI 3→HDMI 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.

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.

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:

Prefix	Command Name	Constant (Space)	Parameter(s)	Suffix
#	Command	-	Parameter

- Feedback format:

Prefix	Device ID	Constant	Command Name	Parameter(s)	Suffix
~	nn	@	Command	Parameter

• 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 (I).
• 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):
