Switcher Error Responses
When the SMX receives an SIS command and determines that it is valid, it performs the
command and sends a response to the host device. If the command is invalid or contains
invalid parameters, the SMX 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/port number
E13 — Invalid parameter (out of range)
E14 — Command not available for this configuration
E17 — Timeout (only caused by direct write of global presets)
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/File not found
