SIS™ Programming and Control, cont’d

Host-to-Switcher Instructions

The switcher accepts SIS (Simple Instruction Set) commands through the RS-232/RS-422 port and Ethernet port. SIS commands consist of one or more characters per command field. They do not require any special characters to begin or end the command character sequence. Each switcher response to an SIS command ends 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 occurs, the switcher responds by sending a message to the host. The switcher-initiated messages are listed below (underlined).

(C) Copyright 2004, Extron Electronics CP 300 450 MAV IP, Vx.xx]

The switcher initiates the copyright message when it is first powered on or when connection via Internet protocol (IP) is established. Vx.xx is the firmware version number.

]Password:

The switcher initiates the password message immediately after the copyright message when the controlling system is connected using TCP/IP or Telnet and the switcher is password protected. This message means that the switcher requires an administrator or user level password before it will perform the commands entered via this link. The switcher repeats the password message response for every entry other than a valid password until a valid password is entered.

]Login Administrator]

]Login User]

The switcher initiates the login message when a correct administrator or user password has been entered. If the user and administrator passwords are the same, the switcher defaults to administrator privileges.

Qik]

The switcher initiates the Qik message when a front panel switching or preset recall operation has occurred.

Sprnn]

The switcher initiates the Spr message when a memory preset has been saved from the front panel. “nn” is the preset number.

Innn Audxx]

The switcher initiates the Aud message when a front panel input audio level change has occurred. “nn” is the input number and “xx” is the dB level.

Outnn Volxx]

The switcher initiates the Vol message when a front panel output audio volume change has occurred. “nn” is the output number and “xx” is the volume level.

Vmtnn*x]

The switcher initiates the Vmt message when a video output mute is toggled on or off from the front panel. “nn” is the output number and “x” is the mute status: 1 = on, 0 = off.
