Switcher Error Responses

When the 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 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 (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
