Switcher Error Responses
When the DXP receives an SIS command and determines that it is valid, it performs the
command and sends a response to the host device. If the switcher is unable to perform
the command because the command is invalid or contains invalid parameters, the 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
E12 — Invalid output number or port number
E13 — Invalid parameter (out of range)
E14 — Command not available for matrix configuration
E17 — System timed out (caused by direct write of global presets)
E21 — Invalid room number
E22 — Busy
E24 — Privilege violation (Ethernet and Extron software only)
E25 — Device not present
E26 — Maximum number of connections exceeded
E27 — Invalid event number
E28 — Bad lename or le not found
E30 — Hardware failure (followed by a colon [:] and a descriptor number)
E31 — Attempt to break port pass-through when it has not been set
NOTE: User privileges extend to all view and read commands except reading the
administrator password. Users can also perform the following functions:
• Creating ties
• Recalling presets
• Muting outputs
Using the Command and Response Tables for SIS Commands
The Command and Response Tables begin on page 55. Upper- and lowercase letters
