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:

(c)Copyright 2004, Extron Electronics MMX (42 or 62), Vx.xx, 60-nnn-nn]

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

Outy•Inn•All]

Outy•Inn•Vid]

Outy•Inn•Aud]

The switcher sends the Outy•Inn message whenever the selected input is changed using the front panel buttons. y is the output number and n is the input number. All, Vid, or Aud indicates both video and audio, video only, or audio only. The power-up default is video and audio input 1 tied to output 1 and output 2.

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

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.
