4-5 CrossPoint 450 Plus and MAV Plus Switchers • Programmer’s Guide
Host-to-Switcher Instructions
The switcher accepts SIS (Simple Instruction Set) commands through the
serial ports 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 2007, Extron Electronics CP 300 450 MAV IP, Vx.xx, 60-nnn-nn{day,
date, time}
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 and 60-nnn-nn is the switcher part number.
{Day, date, time} are only reported 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 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.
