Host-to-Switcher Instructions
The switcher accepts SIS commands through the RS-232 ports and Ethernet port. 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 unit executes
the command and sends a response to the host device. All responses from the unit 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 an equipment power-up, occurs, the unit responds by sending a
message to the host. The unit-initiated messages are listed below:
(c) Copyright 2006, Extron Electronics, MPX 866 A, Vx.xx, 60-825-01
<date/time>]
The switcher issues the
Copyright message (above) when it first powers on. Vx.xx is the
firmware version number and <date/time> is the date and time of the connection.
NOTE: <Date/time> are reported only if the connection is via the LAN port.
]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.
]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.

The switcher initiates the
Qik message when a front panel switching operation has occurred.
Sprnn]
The switcher initiates the
Spr message when a global preset has been saved from the front
panel. nn is the preset number.
Rprnn]
The switcher initiates the
Rpr message when a global preset has been recalled from the
front panel. nn is the preset number.
InnnAudxx]
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.
Typnn•x]
The switcher initiates the Typ message when the video format for a video input is
changed from the front panel. nn is the input number, • is a space, and x is the format:
1 = composite video, 0 = S-video.
