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)
