Extron electronic DXP DVI PRO manual Switcher Error Responses, Special Characters

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 filename or file 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
