Extron electronic MTPX Plus Series Host-to-Switcher Instructions, Switcher-Initiated Messages

Programmer’s Guide, cont’d

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 = ]), 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 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.

]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.
