Host-to-Switcher Instructions
The switcher accepts SIS commands through the RS-232/RS-422 port and Ethernet
port. SIS commands consist of one or more characters per command fi eld. 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 2006, Extron Electronics CP 450 MAV Plus, Vx.xx, nn-nnn-nn,
date/time
]
The switcher initiates the copyright message when it is fi rst powered on or when
connection via Internet protocol (IP) is established. “Vx.xx“ is the fi rmware version
number. “nn-nnn-nn“ is the BME’s part number. “date/time“ is the date and time of
the connection and is only reported when the connection is made via the IP 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 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 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.
Rprnn ]
The switcher initiates the Rpr message when a memory preset has been recalled
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.
