Error Messages
When the MLA receives a valid SIS command, it executes the command and sends a
response to the host device. If the MLA is unable to execute the command because the
command contains invalid parameters, it returns the following error response to the host:
E10 = Invalid command E14 = Not valid for this config.
E13 = Invalid parameter
If the MLA VC10 Plus does not support or recognize the entered commands, nothing will
happen and no response is issued.
