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 (too large)
E10 — Invalid command
E11 — Invalid preset number
E12 — Invalid output number (too large)
E13 — Invalid value (out of range)
E14 — Illegal command for this configuration
E17 — Timeout (caused only by direct write of global presets)
E22 — Busy
E25 — Device not present
E28 — Bad filename/File not found
Using the Command/Response Table
The command/response tables begin on page 4-7. Lower case letters are acceptable
in the command field except where indicated for the gain and attenuation
commands. The table below shows the hexadecimal equivalent of each ASCII
character used in the command/response table.
Symbols are used throughout the table to represent variables. Command and
response examples are shown throughout the table.
