Switcher-initiated messages
When a local event such as a front panel operation or an IR 501 command string occurs, the switcher responds by sending a message to the host. The switcher- initiated messages are listed below (underlined).
The switcher does not expect a response from the host, but, for example, the host program might request a new status.
(C) Copyright 2004, Extron Electronics “MVX nn VGA/A Series”, Vx.xx
The copyright message is initiated by the switcher when it is first powered on. Vx.xx is the firmware version number. “nn” is the matrix size (such as 88, eight inputs by eight outputs).
Qik
The switcher initiates the Qik message when a front panel or IR 501 tie creation has occurred.
Sprnn
The switcher initiates the Spr message when a memory preset has been saved from the front panel or under IR 501 control. “nn” is the preset number.
Rprnn
The switcher initiates the Rpr message when a memory preset has been recalled from the front panel or under IR 501 control. “nn” is the preset number.
Inn Audxx
The switcher initiates the Aud message when a front panel input audio level change has occurred. “n” is the input number and “xx” is the dB level.
Zpa
The switcher initiates the Zpa message when a reset of all audio input levels to 0 dB has been initiated from the front panel.
Exen
The switcher initiates the Exe message when the front panel security lockout (executive mode) is toggled on or off from the front panel. “n” is the executive mode status: 1 = on, 0 = off.
Vmtn 1
The switcher initiates the Vmt message when an IR 501 remote control output video mute command has occurred. “n” is the output number and “1” indicates the mute function is turned on (the output is muted).
Amtn 1
The switcher initiates the Amt message when an IR 501 remote control output audio mute command has occurred. “n” is the output number and “1” indicates the mute function is turned on (the output is muted).
Mutn 1
The switcher initiates the Mut message when an IR 501 remote control output video and audio mute command has occurred. “n” is the output number and “1” indicates the mute function is turned on (the output is muted).
Zpz
The switcher initiates the Zpz message when an IR 501 remote control output unmute command has occurred. All video and audio outputs are unmuted.
