version number. Outy Inn All identifies the currently selected ties, where y is the output number, n is the input number, and All is both video and audio (the power-up default is video and audio output 1 tied to input 1 and video and audio output 2 tied to input 2). The switcher also sends the Outy Inn message whenever the selected input is changed using the front panel

The switcher initiates this message when there is a change in the audio gain setting for any input.

Error responses

When the switcher receives a valid SIS command, it executes the

command and sends a response to the host device. If the switcher is unable to execute the command because the command is invalid or it contains invalid parameters, the switcher returns an error response to the host. The error response codes are:

E01 - Invalid input channel number (out of range)

E10 - Invalid command

The RS-232 protocol of the rear panel RS-232/Remote connector is 9600 baud, 1 stop bit, no parity, and no flow control.

Simple Instruction Set Control

Host-to-interface communications

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command character sequence. When a command is valid, the switcher executes the command and sends a response to the host device. All responses from the switcher to the host 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 operation or error condition, occurs, the switcher responds by sending a message to the host. The switcher-initiated messages are listed below:

The switcher issues the copyright message and the input selected message when it first powers on. Vx.xx is the firmware

E12 Invalid output number (out of range)

E13 - Invalid parameter

Timeout

Pauses of 10 seconds or longer between command ASCII characters result in a timeout. The command operation is aborted with no other indication.

Using the command/response table

The command/response table is on the next page. Lower case letters are allowed in the command field only as indicated. Symbols are used throughout the table to represent variables in the command/response fields. Command and response examples are shown throughout the table. The ASCII to HEX conversion table is for use with the command/response table.
