Error responses
WhentheIPIreceivesavalidSIScommand,itexecutesthecommandandsendsa
response to the host device. If the IPI is unable to execute the command because
the command is invalid or it contains invalid parameters, it returns an error
response to the host.
The error response codes and their descriptions are as follows:
E12 – Invalid port number
E13–Invalidvalue(thenumberisoutofrange/toolarge)
E14–Notvalidforthisconguration
E17–Systemtimedout
E22–Busy
E24–Privilegeviolation
E26–Maximumnumberofconnectionshasbeenexceeded
