SIS Configuration and Control

The SW USB can be remotely set up and controlled via a host computer or other device (such as a control system) that is attached to the rear panel RS-232 port. (See “Wiring for RS-232 Communication” in chapter 2, “Installation,” for information on connecting to this port.) You can issue Simple Instruction Set (SIS) commands to the switcher from your computer using using the RS-232 interface with a communication software program such as DataViewer or HyperTerminal.

Host-to-Switcher Communications

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. When the switcher determines that a command is valid, it executes the command and sends a response to the host device.

Most responses from the SW USB to the host computer end with a carriage return and a line feed (CR/LF = ]), which signals the end of the response character string. A string is one or more characters.

Switcher-initiated messages

When a local event such as a front panel selection takes place, the switcher responds by sending a message to the host, indicating what selection was entered. No response is required from the host.

The following SW USB-initiated message is displayed:

The switcher sends the copyright message when it first powers on. Vx.xx is the firmware version number.

NThis message is displayed only at power-up.

Error responses

If the switcher is unable to execute a command it receives because the command is invalid or contains invalid parameters, the SW USB returns an error response to the host. Error response codes and their descriptions are:

E01 – Invalid input channel number (out of range)

E10 – Invalid command

E13 – Invalid value (out of range)

Using the Command/Response Table

The command/response table on the following pages lists valid ASCII and hexadecimal command codes, the switcher’s responses to the host, and a description of the command’s function or the results of executing the command.

The ASCII to HEX conversion table below is for use with the command/response table.

ASCII to HEX Conversion Table

•

Symbol definitions

] = CR/LF (carriage return/line feed) (hex 0D 0A)

}= Soft carriage return (no line feed)

• = Space E= Escape key

X! = Input number: 0 through the maximum number of inputs (2 or 4)

0 = all inputs disconnected

X#	=	On/off and signal status
		0	= Off/signal not present
		1	= On/signal present
X$	=	X# X# X# X#
		Each X#corresponds to inputs 1, 2, 3, and 4 in
		sequence.
X%	=	Position of the mouse emulation DIP switch
		(SW4 USB Plus only)
		0	= Mouse emulation off (switch is down)
		1	= Mouse emulation on (switch is up)
X^	=	Position of the keyboard emulation DIP switch
		(SW4 USB Plus only)
		0	= Keyboard emulation off (DIP switch is down.)
		1	= Keyboard emulation on (DIP switch is up.)

NUnless otherwise indicated, commands are not case sensitive.
