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
Using the Command and Response Table
The command and response table begins on page 39. Symbols used in the table represent
variables in the command and response fields. Command and response examples are shown
throughout the table. The ASCII to HEX conversion table below is for use with the command
and response table.
