Extron electronic Multi-Graphic Processor MGP 464 Manual De Usuario

When the MGP 464 receives a valid SIS command, it executes the command and 

sends a response to the host device.  If the processor is unable to execute the 

command because the command is invalid or contains invalid parameters, it 

returns an error response to the host.  The error response codes are:
E01 — Invalid input channel number (too large)
E09 — Invalid function number (too large) 
E10 — Invalid command
E11 — Invalid preset number
E12 — Invalid output number (applies for addressing windows)
E13 — Invalid value (out of range)
E14 — Invalid for this configuration
E17 — Invalid command for signal type
E24 — Privilege violation
E26 — Maximum number of users connected has been exceeded
E27 — Invalid event number
E28 — Bad filename/File not found

The MGP 464 can also be controlled via an IP connection using either Telnet 

(port 23) or a Web browser (port 80).  The ASCII and URL commands listed in 

the tables later in this chapter perform the same functions, but they are encoded 

differently to accommodate the requirements of each port (Telnet or browser).  
The ASCII to hexadecimal (hex) character conversion table below is for use with the 

Command/response table for SIS commands, beginning on page 4-9.

•

The command/response tables list valid ASCII (for Telnet) command codes, the 

corresponding URL encoded (for Web browsers) command codes, the processor’s 

responses to the host, and a description of the command’s function or results from 

executing the command.  

  •   Upper- and lowercase letters may be used interchangeably in the command 

field unless otherwise specified.

  •   Commands may be sent back-to-back without spaces; for example, 2*2!2*0B.
  •   Numbers can be entered as 1 digit, or as 2 or 3 digits with leading zeros; for 

example, 8V = 08V = 008V.
