Using Verbose Mode
Telnet connections to an MTPX Plus switcher can be used to monitor for changes
that occur on the switcher, such as front panel operations and SIS commands from
other telnet sockets or a serial port. For a telnet session to receive change notices
from the switcher, the telnet session must be in verbose mode 3. See the Verbose
Mode SIS command on page 4-26. In verbose mode 3, the telnet socket reports
changes in messages that resemble SIS command responses.
Host-to-Switcher Instructions
The switcher accepts SIS (Simple Instruction Set) commands through either serial
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 =
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 2008, Extron Electronics MTPX, Vx.xx, 60-nnn-01 {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-01 is the switcher part number.
N {Day, date, time} are only reported if the connection is via the LAN port.
]
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.
]
]
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.
