Matrix Switcher Error Responses
When the matrix switcher receives an SIS command and determines that it is valid, it
performs the command and sends a response to the host device. If the matrix switcher
is unable to perform the command because the command is invalid or contains invalid
parameters, the matrix switcher returns an error response to the host. The error response
codes are:
E01
— Invalid input channel number (out of range)
E10
— Invalid command
E11
— Invalid preset number (out of range)
E12
— Invalid output number (out of range)
E13
— Invalid value (out of range)
E14
— Invalid command for this configuration
E17
— Timeout (caused only by direct write of global presets)
E22
— Busy
E24
— Privileges violation (Users have access to all view and read commands [other than
the administrator password], and can create ties, presets, and audio mutes
E25
— Device not present
E26
— Maximum number of connections exceeded
E27
— Invalid event number
E28
— Bad filename / file not found
Using the Command and Response Tables
begin on page 87. Symbols used in the tables
represent variables in the command and response fields. Command and response examples
are shown throughout the tables. With the exception of the audio input gain and attenuation
commands, the SIS commands are not case sensitive. The ASCII to HEX conversion table
below is for use with the command and response table.
