SVS 100 error responses
When the SVS 100 receives an SIS command and determines that it is valid,
it performs the command and sends a response to the host device. If the SVS
100 is unable to perform the command because the command is invalid or
contains invalid parameters, the SVS 100 returns an error response to the
host. The error response codes are:
E01 — Invalid input number
E09 — Invalid function number (too large)
E10 — Invalid command
E11 — Invalid preset
E13 — Invalid value (out of range)
