Processor-Initiated Messages
When a local event such as a front panel operation occurs, the processor responds by
sending a message to the host. The processor-initiated messages are listed below.
With an Internet connection:
(c) Copyright 2014, Extron Electronics, ANNOTATOR 300, Vx.xx,
60-1316-01]
Ddd, DD MMM YYYY HH:MM:SS (day, date time. Tue, 14 Jun 2014 14:43:17)
The processor initiates the copyright message when powered on or when connection via
Internet protocol (IP) is established. Vx.xx is the firmware version number.
]Password:
The processor initiates the password message immediately after the copyright message
when the controlling system is connected using TCP/IP or Telnet and the processor is
password protected. The processor requires an administrator or user level password
before performing the commands entered.
NOTE: Password prompt is re-displayed if an incorrect password is entered.
]Login Administrator] and ]Login User]
The processor initiates the login message when a correct administrator or user password
has been entered. If the user and administrator passwords are the same, the processor
defaults to administrator privileges.
Reconfig]
The processor sends the Reconfig message whenever any change of the input frequency,
video format, or audio format; on the currently selected input is detected.
NOTE: Response is seen via verbose connections only.
Exen]
The processor initiates the Exe message when executive mode is toggled on or off from
the front panel. “n” is the executive mode status: 1 = on, 0 = off.
HplgOx]
The processor initiates the SIS response that is broadcast upon detection of a Hot Plug
event on output x.
Processor Error Responses
When the Annotator 300 receives an SIS command and determines that it is valid, it
performs the command and sends a response to the host device. If the processor is
unable to perform the command because the command is invalid or contains invalid
parameters, the processor returns an error response to the host. The error response
codes are:
E01 — Invalid input channel number (out of range) E22 — Busy
E10 — Invalid command E24 — Privilege violation
E11 — Invalid preset number E25 — Device not present
E12 — Invalid port number E26 — Maximum number of
E13 — Invalid parameter (out of range) connections exceeded
E14 — Command not available for this configuration E27 — Invalid event number
E17 — Invalid command for this signal type E28 — Bad filename/file not
found
