SGS 408 Switcher • Serial Communication
SGS 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 number (too large)
E10 — Invalid command
E11 — Invalid preset
E12 — Invalid output number (too large)
E13 — Invalid value (out of range)
E23 — Checksum error
Using the command/response table
The command/response table begins on the next page. Lower case letters are
acceptable in the command field only where indicated. Symbols are used
throughout the table to represent variables in the command/response fields.
Symbol definitions are shown at the beginning of the response table, as is an
ASCII-to-hexadecimal conversion table. Command and response examples are
shown throughout the table.
